Could not start Diagnostic Policy Service

One of the most useful utilities for advanced users in Windows is the Windows command line or Command Prompt. It is efficient in fixing system files, checking the disk for errors as well as other intensive tasks that are made convenient using this. One of the tasks you can carry out using Command Prompt is repairing the Windows bootup process if it encounters any issues. However, if you tried running the “bootrec/fixboot” command and you receive an error message saying, “Element not found”, read on as this post will guide you in fixing this error. This kind of error in the command line could be due to a damaged BCD or MBE, inactive system partition, or it could also be that there is no drive letter being assigned to the EFI partition. Whichever the case is, here are some possible fixes that should help you resolve the problem.

Option 1 – Try to repair BCD

As mentioned the error could be caused by a damaged BCD and so to fix the problem, you need to repair BCD by following these steps:

• First, make sure that you have a bootable Windows 10 USB drive with you and use it to boot your computer.
• Once you’re on the Welcome Screen, click on Next.
• After that, click on Repair your computer located at the bottom-left portion of the window.
• Then select Troubleshoot > Advanced Options > Command Prompt.
• After you open the Command Prompt window, execute the following command:

bootrec /fixboot

• Afterward, enter the next command below to rename the BCD file:

ren BCD BCD.bak

• Next, type the following command and make sure to replace “b:” with the letter of your bootable drive attached to your computer.

bcdboot c:Windows /l en-us /s b: /f ALL

• Now, wait until the process is completed and restart your computer to successfully apply the changes made.

Option 2 – Try assigning the drive letter to the EFI partition

• Tap the Win + X keys or right-click on the Start button and click on Command Prompt (Admin) to open Command Prompt with admin privileges.
• Then type the following command to start the Diskpart utility:

diskpart

• After that, if you receive a UAC prompt, just click on Yes to proceed.
• Next, type the following command to list all the volumes created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files:

list volume

• Now type the following command to select the desired volume:

select volume number

• Then type the following command to assign a letter to the selected volume:

assign letter=<LETTER>

Note: Make sure to replace “<LETTER>” with the letter you want to allocate to that partition. Afterward, it will assign a letter to the selected volume.

• Reboot your PC to apply the changes made.

Option 3 – Try setting the System Partition to Active

Like the first given option, you also have to make sure that you have a bootable Windows 10 USB drive before you proceed to set the System Partition to Active. Once you have it covered, refer to these steps:

• Boot your computer using the bootable Windows 10 USB drive.
• Next, click Next when you get to the Welcome Screen.
• Then click on Repair your computer located at the bottom left part of the window and select Troubleshoot > Advanced Options > Command Prompt.
• After opening Command Prompt, type the following command and hit Enter to start the Diskpart utility. It is a command line-based utility just like Command Prompt but has a UAC prompt once you provoke it. So if you encounter a UAC prompt, just click on Yes to proceed.

diskpart

• Now type the following command:

list disk

• From there, select your primary disk by typing the following command:

select disk number

• After that, list all the partitions on the selected disk by entering the following command:

list partition

• The command you just entered will list all the partitions created on your PC including both types of partitions that are visible to a normal user in the File Explorer as well as the ones created by Windows 10 by default which helps it in storing the boot files and other important system files.
• Now type the following command to select the partition that is usually around 100 MB in size:

select partition number

• Finally, type the following command to mark the partition active:

active

• Then type the “exit” command to exit the disk part utility.

If there are any third-party add-ons or proxy settings that interfere with your Windows 10 computer’s internet connection, then you will most likely encounter a problem where you see an error message saying, “Website is online but isn’t responding to connection attempts” when you try to run the Network Adapter troubleshooter. Like pointed out, this kind of error can be caused by some proxy settings that prevent the connection. On the other hand, it could also be caused by some third-party add-ons. To fix this error, read on as this post will guide you on what you can do to fix it. You can try to turn off the proxy settings or disable the add-ons on your browser. You can also try resetting both the TCP/IP and DNS as well as reset the network. For more details, refer to the options provided below.

Option 1 – Try to turn off the proxy settings

There are some users who reported that they’ve fixed the problem after they’ve disabled the use of a proxy server using the built-in way. Follow the steps below to disable the proxy server.

• Tap the Win + R keys to open the Run dialog box.
• Then type “inetcpl.cpl” in the field and hit Enter to pull up the Internet Properties.
• After that, go to the Connections tab and select the LAN settings.
• From there. Uncheck the “Use a Proxy Server” option for your LAN and then make sure that the “Automatically detect settings” option is checked.
• Now click the OK and the Apply buttons.
• Restart your PC.

Note: If you are using a third-party proxy service, you have to disable it.

Option 2 – Try disabling the add-ons or browser extensions

The next thing you can do to fix the problem is to disable any extensions or add-ons on your browser. For instance, if you are using Chrome, here’s what you have to do:

• Open Chrome and press Alt + F keys.
• Go to More tools and click Extensions to look for any suspicious browser extensions or toolbars.
• Click the Recycle bin and select Remove.
• Restart Chrome and press Alt + F keys again.
• Proceed to On Startup and mark Open a specific page or set of pages.
• To check if the browser hijacker is still active, click Set pages, if it is active, overwrite the URL.

Option 3 – Try to update the Network Adapter Driver

Follow the steps below to update your Network Adapter Driver:

• Tap the Win + R keys to launch the Run window and then type in the “MSC” command and hit Enter to open the Device Manager window.
• From there, expand the list of all the network drives and update each one of them.

Note: If updating the network drivers didn’t help in fixing the problem, you can also try to uninstall the very same drivers and restart your Windows 10 PC. After that, the system itself will reinstall the drivers you just uninstalled. Alternatively, you can also download and install the drivers from the manufacturer’s website directly.

Option 4 – Try to reset the TCP/IP and the DNS cache

As you know, the TCP/IP or the Internet Protocol is the most important thing if you want to use the internet on your computer. That’s why if it ends up getting corrupted, you need to reset the TCP/IP to fix the problem. To reset TCP/IP, refer to these steps:

• In the Windows start to search, type “command prompt” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, execute this command: netsh int ip reset resettcpip.txt
• Next, execute this second command: ipconfig /flushdns
• Once it’s done, exit Command Prompt and restart your computer and then check if the error is now fixed.

Option 5 – Try to reset the Network

You can also try to perform a Network Reset to resolve the problem. This will reset the entire network configuration including your IP address. To perform Network Reset, follow these steps:

• Tap the Win + I keys to open Settings.
• From there, go to the Network and Internet section.
• Next, scroll down and look for “Network Reset” under the status pane.
• After that, click on Network Reset and then on Reset now to start resetting the network configuration. Once done, check if it is able to fix the error or not.

There are times when you might notice that the Drive letter from the File Explorer is missing, right after you install an update in your Windows 10 computer. So if you are facing this issue right now, then you’ve come to the right place as this post will guide you on what to do to fix it. In case you don’t know, a drive letter represents a single alphabetic character which is through A-Z typically. This could be assigned to a physical disk partition, floppy disk drive or the removal device/ CD-ROM/ mapping network drive in your PC. In most cases, the drive letter “C:” is assigned to the first disk partition where the running Windows is installed. Thus, if the assigned letter is missing from either the Disk Management or the Windows File Explorer, it could result in inconveniences or will leave the partition inaccessible. To fix this problem, you can try to show the missing drive letters manually or make sure that the drive has a drive letter assigned in the Disk Management as well as assign the letter using a tweak in the Windows Registry. For more details, refer to the options provided below.

Option 1 – Try to show the missing drive letters manually

• Open the Folder Options from the Start Search and go to the View tab,
• Next, scroll down on the list of given options until you see the “Show drive letters” option and then check the box that’s marked against this option.
• After that, click on the Apply and OK buttons and then go back to the “This PC” window. You should now see the drive letters

Option 2 – Make sure that the drive has a drive letter assigned in Disk Management

As you know, every drive is assigned a drive letter in Disk Management. However, if it goes missing, you can still get it back through Disk Management. To do so, follow the steps below.

• Open Disk Management and from there, right-click on the menu of a partition or volume and you should see a function named “Change Drive Letter and Paths”.

Note: This function allows you to add the drive letter, remove the drive letter and change the drive letter. If the last option, namely, “Remove”, is selected and applied, the letter of the drive will be removed and won’t appear in Disk Management. Thus, this could be one of the reasons why a drive letter is missing.

• You need to click on “Add” to assign a letter to the selected drive in order to reverse the change. Note that you must assign the drive with the original letter because if not, the programs that rely on the original letter might not work as expected.
• If the original letter is already taken by a new drive, you need to change the letter of that new drive to another available letter.
• Then allocate the released letter of the targeted drive.

Option 3 – Try assigning the letter using a Registry tweak

The next thing you can do to fix the problem is to assign the letter using a tweak in the Windows Registry but before you do that, make sure that you create a System Restore point first, after that, follow these steps:

• Tap the Win + R keys to open Run and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to this registry path: HKEY_LOCAL_MACHINESYSTEMMountedDevices
• From there, check if a device is shown as being mounted at the specific drive letter and then right-click on that drive letter.
• Select the “Rename” option from the right-click menu to change the letter to any other available letter.
• Exit the Registry Editor and restart your computer.

Option 4 – Try to format the destination drive

Formatting the drive can also help you resolve the error. To format it, follow these steps:

• To get started formatting your drive, tap the Win + E keys and then go to the access page of the drive.
• Next, right-click on the drive and select Format.
• After that, uncheck the “Quick Format” option and then format your drive properly.
• Now once the formatting process is finished, unplug the drive and plug it back in afterward.
• Check if the error is already fixed. If the drive is not initialized, tap the Win + R keys and hit Enter.
• After opening the Run dialog box, type “diskmgmt.msc” and hit Enter to open Disk Management.
• From there, right-click on the drive volume and select initialize disk.
• Next, select the correct partition type and proceed.

What is Solimba?

Solimba is a bundled executable program. It was created to be launched as a promotional tool to get advertisements loaded on a user’s system, upon installation. As a bundle, Solimba offers installation of various programs, with the objective of promoting various products and services. It utilizes unethical techniques, as in the case with adware tactics to influence or for want of a better word, hijack an Internet Browser to affect a website’s result on a search results page. In this assessment, Solimba distributed ads on Internet Explorer, Chrome, and Mozilla browsers, by hijacking various Internet Browsers to change the user's experience. (Images are shown below) Technical details about Solimba PUP include:

Digital Signature:  POPELER SYSTEM, S.L. Entry Point:   0x0000C1DC

Assessment of Solimba Potentially Unwanted Program

Solimba PUP is all about the ads. Once this executable is installed, it penetrates your computer system and sends ads all over your Internet Browser – Chrome, Internet Explorer, Mozilla Firefox, and the likes. For this assessment of Solimba.exe PUP, two installations were carried through. In layman's terms, I actually installed Solimba on two occasions to decipher the true nature of the PUP. It was shocking to find that both installations revealed different bundled programs and advertisements. In the first instance (as shown below), Solimba proved more aggressive in featuring ads for revenue advancements.

 Solimba employed aggressive advertising techniques

It’s important to note that hijacked results resulting from the installation of Solimba. This affected the results of the website on the Internet browser to boost its ranking, even without the use of a search engine. The advertisement displayed on the Internet Explorer search page routes the user to a software installation website. The utility tool in question was a “Windows 8.1 PC Repair” tool used to identify threats present on the Windows 8.1 OS. The advertisement displayed on the Chrome Browser search page routes the user to a health and beauty magazine website. This site advocates health and beauty, especially issues concerning weight loss. Several ads were visible on-site, displaying products to assist people in losing weight. During my installation of Solimba, the installation wizard underscored that four programs would be downloaded. These programs included N8Fanclub.com_KinoniRemoteDesktop, Lolliscan, PaceItUp, and SearchProtect. Interestingly, only two programs from the list were apparent or obvious. An N8Fanclub.com_KinoniRemoteDesktop file was made on the Desktop and SearchProtect was seen in “All Programs”, along with files stored on the computer’s Local Drive. The other programs that were “supposedly” installed remained concealed. A test was done to determine whether these were counted as extensions or add-ons to the varying web browsers but nothing was found on any of the tested browsers – Google Chrome, Internet Explorer, and Mozilla Firefox.

Description of 4 Installed Files

N8Fanclub.com_KinoniRemoteDesktop

When this file was initially found on the Desktop, a rootkit came to mind. A rootkit was used as a means to an end. Whoever was on the receiving end of this unwanted file would be able to connect to an infiltrated system without the knowledge of the user. After running the file to determine its behavior, nothing much happened. A message appeared indicating that the software couldn’t execute on the computer. That was pretty tricky since, to begin with, I didn’t place that specific file on the desktop but it came along with the territory and so I had to accept it. Further research online into N8Fanclub.com_KinoniRemoteDesktop proved very rewarding. A search of the entire file name was not able to do the trick so I had to do research on both terms separately. After landing on N8Fanclub.com, I was nicely asked to disable my adblocker. There seemed nothing harmful about the site. However, due to the fact that it was not what I initially installed, the program was an unwanted program. That’s exactly what Solimba does. It installs several other programs that were not requested by the user in an attempt to make money from advertising. The mere fact that this program got installed meant that it was to promote an online service.

KinoniRemoteDesktop

was a separate program. It was combined with N8Fanclub as a way to allow users to use their PC computer “as if they were sitting in front of it.” A user would be able to make use of a full web browser, watch Flash videos, play games, and even use office applications. This would be done from the user’s Nokia device. This is an advertisement at its best.

Lolliscan

This program did not allow me to see much since it didn’t leave a physical trace behind. However, during the installation, Lolliscan was listed as one of the four programs that would be installed. Overall, Lolliscan supposedly should be able to save people money since this form of the ad focuses on showing coupons when visiting sites such as Amazon. While this seems like a good deal, this ad will invade your personal space and distribute pop-ups at the most inopportune times.

PaceItUp

As the name states, PaceItUp is software added to a browser with the intent to speed your computer. Quite the contrary, PaceItUp does the total opposite since it installs bundled programs that slow down a computer system. PaceItUp is also known for displaying ads and tracking what the user does on his/her computer system.

SearchProtect

It’s known for hijacking your computer’s homepage. In fact, this addition is very stubborn and often possesses a challenge when a request to uninstall is made.

Further Information on Solimba

The second installation of Solimba also had its own dose of bundles to display. In comparison to the first installation, two programs from the bundle were different while two remained the same. two additional programs were installed along with the second installation of this bundle. These were dubbed Optimizer Pro and GamesDesktop. SearchProtect and N8Fanclub.com_KinoniRemoteDesktop remained triumphant and unbeatable. They were repeated within the installation. To completely remove Solimba from your computer, click here to download and install Spyhunter.

Windows comes with a built-in backup solution. However, if it failed because of an internal error, you will encounter an error message saying, “The backup application could not start due to an internal error, Server execution failed (0x80080005)”. When you get this kind of error, it means that it did not start and the process failed with a Server execution error. If you got this kind of error worries not for this post will guide you in fixing the problem in your Windows 10 computer. The Windows Backup service is an excellent feature in Windows that only works on the NTFS file system and if you want to use this make sure that you have formatted your files system to NTFS. It is performed by the Volume Shadow Copy, all you have to do is right-click on any folder and if you see the “Previous versions” option, this means that a backup process runs from time to time and can bring back old files when needed. To resolve the “The backup application could not start due to an internal error”, here are two suggestions you can check out.

Option 1 – Check if the Volume Shadow Copy service is running and restart it

The first thing you need to do is check if the Volume Shadow Copy service. To do that, refer to the following steps:

• Click on Start and type “cmd” and right-click on Command Prompt from the search results.
• Then select the “Run as administrator” option to open Command Prompt with admin privileges.
• After that, type “net stop sdrsvc” and hit Enter to execute the command in stopping the Volume Shadow Copy service.
• Next, type the “net start sdrsvc” command and hit Enter to start the service again.

Note: You can also restart the service using the Windows Services Manager.

• In the Cortana search box, type “services” and click on the Services icon to open the Services Manager. Alternatively, you can also tap the Win + R keys to launch the Run prompt and then type “services.msc” in the field and hit Enter to open the Services Manager.
• From there, look for the Volume Shadow Service (sdrsv) from the list of services. Its Startup type should be set to Manual by default.
• Restart the service and if you don’t encounter any error while you turn it on, re-run the backup service and see if the backup process runs successfully.

Option 2 – Try to run the Volume Shadow Copy Service in a Clean Boot State

If the first option didn’t work and the service still keeps on failing even though the service is running, you can try putting your computer in a Clean Boot State and then try to run Windows Backup again.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Now try to run the Volume Shadow Copy service again and see if the process goes smoothly.

Note: You might also want to delete all the files in the backup solution if you want to start fresh with the backup solution. Just go to C:/System/Volume/Information/Windows Backup and take ownership of the folder. After that, make sure to stop the Volume Shadow Copy service and then delete all the files inside it.

When performing a Windows Backup to the NAS device (backup to a network share) that is running Samba, fails with an error message The backup failed, The version does not support this version of the file format (0xC03A0005). The problem occurs because of a conflict with the VHD file that is created by Windows Backup and is mounted during the process. There are three types of VHD files:

1. Fixed,
2. Expandable
3. Differencing

If the VHD file is a sparse file that is not supported by the native VHD driver, the mounting will fail, and you will get this error. An example VHD file is one that keeps expanding depending on the backup size. The problem occurs only in the case of  File Level backup (file/folders in a volume) but not on the block level backup as the vhd file is never mounted. However, in the case of File Level Backup, the vhd is mounted, created by Windows Backup, which does not support the mounting of sparse files.

The solution is to use Strict Allocate: option in the smb.conf file

Login to SMB using SSH. Open the configuration file using the VI editor located at /etc/samba/smb.conf. If the option is not there, you can manually add strict allocate = yes which will make sure there are no sparse file that is created.

As you probably know, Windows 10 does not offer lots of choices for its Regional settings depending on where you are and what locale you work with or belong to. The standard region settings for Windows 10 allow users to select one set of formats for the calendar and more. However, this has somewhat changed in the Windows 10 v1809. If you don’t want such a change, you can just override the default regional format settings in the Windows 10 Improved local experience. So in this post, you will be guided on how you can do such a thing. Follow the given instructions below to override the default Regional Format settings in Windows 10. Step 1: Go to Settings > Time and Language > Region. Step 2: From there, the default region is what Windows and apps might use to provide you with local content. However, this won’t be much of use if you work for a different locale and need to have different format settings like Calendar, Dates, Times, Currency, and First day of the week, all of which you can modify under the Regional format. Step 3: You need not reboot your Windows 10 computer after changing. On the other hand, some of the apps will have to close and launch again in order to apply the new format. Thus, if you need to use apps that are of different locales, you will only see the changes after you re-launch the app. Note: You can also select a different language that makes more sense to you. In other words, if you prefer more common words to standard words for your Windows 10 computer, then this is definitely the way to do it. This local format will be used for messages, menus, navigation, settings, and other topics. Step 4: Look for a link that says “Add a Windows display language with local experience packs” under Languages. In case you don’t know, Local Experience Packs are Microsoft Store apps that deliver Windows display language quality improvements. So once you click the link, it will download the packs from the Microsoft Store. In addition, Windows has already begun using AI or Artificial Intelligence as well as neural network-based Machine Learning for Windows localization. And as the number increase, the Machine language improvements and feedback from users will help in making the translations a lot better and make them available to even more languages. All in all, it’s pretty much an interesting and a good move for Microsoft as the demands for topics and machines to be available in local languages have been increasing for the past couple of years.

The Makecab.exe process that’s running on your Windows 10 computer is a program that compresses the Component-Based Servicing log or CBS log files and they can get really huge if they’re not compressed. As a result, it would utilize important space on your operating system although makecab.exe does not consume high CPU resources in doing so. However, there are times when it recreates thousands of instances of itself and could cause overconsumption of system resources which slows down your computer. So when the makecab.exe process causes high CPU usage in your system, this could mean that there is a failed Windows Update. In addition, the high CPU usage of the makecab.exe process could also mean that your computer is infected with a virus or malware. Whichever the case is, you can check out several possible solutions that are given in this post to resolve the problem.

Option 1 – Try to delete log file using File Explorer

The CBS log files could reach up to 20GB size and so if you delete them, it would help in saving space in your computer and since they’re not much of use, deleting them won’t negatively affect the system at all. To delete the CBS log files, all you have to do is open the File Explorer and then go to C:/Windows/Logs/CBS and from there, open the CBS log files and delete them all. Doing so should ease the load in the makecab.exe process since it no longer has to compress the CBS log files. As a result, the process would be more relaxed. After that, you can restart your computer and check if the problem’s now fixed.

Option 2 – Try deleting the log file via Command Prompt

You can also try to delete the log files using an elevated Command Prompt. Refer to these steps to do so:

• Type “command prompt” in the Windows Search bar and then right-click on the related search result and select the “Run as administrator” option.
• Next, type the following command and hit Enter to execute it:

del /f %windir%logscbs*.log

• Restart your computer afterward once the command has been executed. This should end the high disk usage by makecab.exe, if not, proceed to the next given options below.

Option 3 – Uninstall any suspicious programs you’ve installed recently

If you have recently installed some programs on your Windows 10 computer, and since then you’ve experienced high CPU usage brought on by makecab.exe, then you might want to uninstall those programs.

• Tap the Win + R keys to open the Run dialog box
• Then type “appwiz.cpl” in the field and hit Enter to open the Programs and Features in Control Panel.
• From there, look for the suspicious programs you’ve installed, select them and then click on Uninstall to remove them.
• After that, restart your computer and try to install the latest version of the program again. It should work now. If not, proceed to the next available option below.

Option 4 – Try running Disk Cleanup

You might want to run the Disk Cleanup utility as it is a useful tool that could delete temporary and useless files on your computer.

• Tap the Win + R keys to open the Run dialog box and then type “cleanmgr” in the field and hit Enter to open the Disk Cleanup window.
• After that, select the drive you want to clean.
• Now click OK to clean the disk and restart your computer.

Option 5 – Try to run System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files and missing files. It replaces bad and corrupted system files to good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your PC.

Option 6 – Try scanning your computer using Windows Defender

As mentioned, the high CPU usage of makecab.exe might be caused by some malware or virus in the system and so to eliminate it, you have to scan your computer using security programs like Windows Defender.

• Tap the Win + I keys to open Update & Security.
• Then click on the Windows Security option and open Windows Defender Security Center.
• Next, click on Virus & threat protection > Run a new advanced scan.
• Now make sure that Full Scan is selected from the menu and then click the Scan Now button to get started.

As you know, one of the basic apps in the Windows 10 operating system is the calculator and it can even be extended to a scientific calculator which makes it really useful for users. However, there are instances when you might encounter some issues while using this app. One of the issues about the Calculator app that’s been reported recently is that the Calculator app is not working. If you encounter the same problem, then you’ve come to the right place as this post will guide you on what you can do to fix the problem. Based on the reports, users claimed that the issue with the Calculator app occurred right after they’ve installed a feature update, while other users claimed that the Calculator app never really worked on their computers and there are also cases where the app opens but it either freezes or crashes. According to researchers, the main causes of the problem include a feature update that could’ve altered the settings. It could also be due to problems with the login account or corrupted and missing files, or the problem could also with the calculate app itself. To resolve this problem, here are some suggestions you can follow.

Option 1 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the reason why the calculator app is not working properly. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Reboot your computer.

Option 2 – Run the DISM tool

You can also run the DISM Tool as it helps in repairing the Windows System Image as well as the Windows Component Store in Windows 10. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth” that could help in fixing the Calculator app.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • Dism (.)exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish.

Option 3 – Try logging into your computer using a different User Account

You might want to try logging into a different User Account since it is possible that the issue could have something to do with your log-in account. Thus, you can isolate this possibility by logging into a different user account. If you don’t have any other user account, simply create a new one by clicking on the Start icon and then go to Settings > Account > Family & other users. From there, go to the Other user's section and click on the Add someone else to this PC option, and then inputs all the needed information and restarts your computer. Once your computer has restarted, log into your computer using the newly created user account.

Option 4 – Try to reset or reinstall the Calculator app

If the first three given options didn’t work, you might want to reset or reinstall the Calculator app. To do that, follow these steps:

• Click on the Start button and go to Settings > Apps > Apps and features.
• Next, look for the Calculator app from the app list and click on it to see its other options.

If you are using File Explorer but suddenly encountered an error saying, “No such interface supported”, read on as this post will guide you on how to fix the problem. This kind of error occurs due to the corruption in the system files which supports several tasks in the system that works with the Windows File Explorer process or File Explorer. This kind of error can give you a hard time in browsing the files on your computer, or when you open important utilities like the Control Panel, or when you copy files and other inconveniences. Needless to say, it won’t bring you any productivity at all and can only leave you frustrated. To fix this problem, there are several options you can try. You can try to run the System File Checker scan or the DISM tool. You could also try to re-register the potentially corrupted DLL files or fix the User Profile. For more details, refer to each one of the given options below.

Option 1 – Try to run System File Checker

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files to good system files that might be the cause why you’re getting the errors 0x8024a11a and 0x8024a112. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer and see if the problem is fixed or not.

Option 2 – Try to fix the User Profile

The next thing you can do to fix the problem is to fix the User Profile. All you have to do is migrate to a new User Profile in Windows 10 by creating a new User Account and migrating all your personal files from the current user profile folder in the C:/Users location to the new user profile folder which is also located in the same folder.

Option 3 – Run the DISM tool

You can try running the Deployment Imaging and Servicing Management or DISM tool to fix the “No such interface supported” error. Using this built-in tool, you have various options such as the “/ScanHealth”, “/CheckHealth”, and “/RestoreHealth”.

• Open the Command Prompt with admin privileges.
• Then type in the following commands and make sure to hit Enter right after you type each one of them:
  • Dism /Online /Cleanup-Image /CheckHealth
  • Dism /Online /Cleanup-Image /ScanHealth
  • exe /Online /Cleanup-image /Restorehealth
• Do not close the window if the process takes a while as it will probably take a few minutes to finish. Once it’s done, restart your computer.

Option 4 – Try to re-register the problematic DLL file

You may have to re-register the ntdll.dll file using the regsvr32.exe before you can successfully install the program and fix the error. The Regsvr32 tool is a command-line utility that can be used to register and unregister OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. Follow the steps below to use it.

• Open Command Prompt as admin from the WinX menu.
• Next, type the following command in the elevated Command Prompt and hit Enter to execute it. This will re-register the affected DLL file using the Windows operating system tool, regsvr32.exe.

regsvr32 c:windowssystem32actxprxy.dll

• After you execute the given command, you should see a message saying, “DllRegisterServer in vbscript.dll succeeded” if the Regsvr32 tool was able to run successfully. If it didn’t work, you can try to execute this command instead: FOR /R C: %G IN (*.dll) DO "%systemroot%system32regsvr32.exe" /s "%G"
• Once it’s done, restart your computer.
