Windows Sandbox item is greyed out

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.
• After that, select the Advanced options and go to the Reset section and then click on the Reset button to reset the Calculator app.

Note: You also have the option to reinstall the Calculator app. All you have the option to visit Microsoft Store and from there, uninstall the Calculator app.

As you know, Diskpart is a useful utility that helps in managing the disks in a computer. It is a very useful tool that even when the GUI-based disk management tools in Windows 10 operating system fails, the Diskpart utility still tends to work. However, it also does not mean that this utility does not experience issues as it still does, from time to time. One of the issues you may encounter when using the Diskpart utility is when you encounter an error message that says, “DiskPart has encountered an error, Access is denied”. This kind of error in the Diskpart utility could be caused by a number of factors. For one, it could be that the Write-Protection is enabled on the drive where the operating is being performed or it could also be that the Command Prompt terminal does not have administrator-level permissions to carry out the command. Thus, you can try to run the Diskpart utility again but this time with admin privileges or you could also remote the Write-Protection from the concerned drive. For more details, refer to the instructions given below.

Option 1 – Try running Command Prompt with Administrator-level permissions

• In the Start Search, type “command prompt” and from the search results that appear, look for Command Prompt.
• Once you found it, right-click on it and select the “Run as administrator” option.
• After that, try to execute the Diskpart operation once again and see if you still encounter the same error.

Option 2 – Try to remove the Write Protection from the drive

As mentioned, removing the Write-Protection on the concerned drive could also help you fix the problem and there are two ways to get rid of the write protection – you can either use the Diskpart utility or the Registry Editor. How? Refer to the following steps.

Via Diskpart utility:

• Open Command Prompt with admin privileges and then type the “diskpart” command and tap Enter to execute it.
• Next, type “list disk” and tap Enter to get the list of all the Disk connects or all the partitions that are formed on those disks.
• After that, you need to choose one command depending on the list of commands you entered. Type “select disk #” and tap Enter to select the disk or partition you want to select.
• Then type “attribute disk clear readonly” and tap Enter to Disable the Write Protection on the selected disk or partition.

Via Registry Editor:

• Tap the Win + R keys to open the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
• Next, navigate to the following registry key:

ComputerHKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlStorageDevicePolicies

• After that, look for the DWORD named “WriteProtect” and double click on it, and then set its Value Data to “0”.
• Now restart your computer and see if the problem is now fixed or not.

If you encounter an error message saying, “ERR SSL VERSION OR CIPHER MISMATCH” while visiting a website, then it is not primarily your fault as an end-user. In fact, it can happen on any website like Chrome, Edge, Firefox, and even Internet Explorer. Getting this error means that the website you are visiting is using an SSL certificate which your browser seems to be rejected because there is some issue with the certificate. It is also possible that the certificate that’s downloaded on your computer is corrupted or that your computer configuration for TSL/SSL is misconfigured. Here are the complete details of the error message:

“A secure connection cannot be established because this site uses an unsupported protocol, Error code ERR_SSL_VERSION_OR_CIPHER_MISMATCH”

To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error, refer to the options given below and see which one works for you.

Option 1 – Try to access the website with the only HTTP

The first thing you can do is to try accessing the website using HTTP instead of HTTPS. If you can open the website using HTTP then it means that the problem is in the website itself. And if you are the website owner, you can check the following:

• Check if your website’s SSL certificate name is mismatched. Here you need to ensure that the name and alias of the websites match with the actual website URL where the certificate is installed.
• Second, check if your server is using the RC4 Cipher. If it is, then you need to fix that.

On the other hand, you may also check if your CDN also supports SSL since most of the CDN nowadays supports SSL. All you have to do is configure it correctly and it should be good to go.

Option 2 – Try enabling SSL 3 / TLS and disable QUIC Protocol

If you were using Google Chrome when you got the ERR SSL VERSION OR CIPHER MISMATCH error, then you need to follow the protocol fixes for SSL3/TLS and QUIC which are usually some of the reasons that cause the SSL version / Cipher Mismatch. It also has a few fixes for Windows 10 computer where you can clear the certificates and make sure that your computer date and time is in sync with your time zone and so on. If you were using Edge or Internet Explorer when you got the error, then you have to follow the steps below.

• Type “Internet” in the search box of your browser. After that, you should see the Internet Options from the search results.
• Next, open the Internet Properties window and switch to the Advanced tab and then scroll down to the Security section.
• From there, check the “Use TLS 1.1” checkbox as well as the “Use TLS 1.2” checkbox and then click OK to save the changes made.
• Restart the browser.

On the other hand, if you were using Firefox when you go the error, here’s what you have to do.

• Open Firefox and in the address bar, type “about:config” and hit Enter.
• If a warning appears, just click on the “I accept the risk!” button to proceed.
• Next, type in “TLS” in the search field and hit Enter.
• Then look for “security.tls.version.min” and double click on it and set its integer value to 3 to force the protocol of TLS 1.3.
• Now click OK and restart Firefox and do the same thing with SSL.

If you would like your computer to be discoverable on your network and use print and file sharing you will have to change your network profile on your computer from public to private.

Switch to private profile in Windows 10

Locate the Wi-Fi icon in your system tray and click on it. Click on properties on your WI-FI network to open the network menu. Inside the menu in the Network profile section enable the Private option.

Your changes will be automatically saved.

Switch profile to private in Windows 11

Find the WI-FI icon in the system tray and right-click on it, then choose Network and Internet Settings. Network & Internet page with open, find your network name at the top and select properties.

On the WI-FI page, in the Network Profile Type section choose Private. As in Windows 10, your changes will be automatically charged, and you can start using them immediately.

Another way around

If you want to switch back to a public profile follow provided steps but disable the private option.

One of the most interesting innovations that were released by Microsoft is the Surface Dial. This only goes to show that Microsoft is very competent not just in hardware but in overall innovation. Although it’s quite a piece of technology and as far as the consensus is concerned, it works pretty well, there are still some issues encountered by users. One of the particular issues experienced by users is that the Surface Dial fails to pair with every Windows 10 PC. At a time of writing, it is still not clear what the cause of the problem really is. However, their possible solutions are provided in this post that might help you resolve the problem. Before you get started troubleshooting the problem, make sure that there are two AAA batteries fitted inside properly.

Option 1 – Check if your PC supports Bluetooth 4.0 LE

In case you don’t know, the Surface Dial only works with the Windows 10 Anniversary Update and later PCs that support Bluetooth 4.0 LE. Thus, you have to check if this is supported or not before you troubleshoot further.

• Tap the Win + R keys on your keyboard to open the Run dialog box.
• Next, type “devmgmt.msc” in the field and hit Enter to open the Device Manager.
• From there, click on Bluetooth and select “Microsoft Bluetooth LE Enumerator” from the drop-down menu. However, if it is not there, then it simply means that your computer does not support this standard which is most likely why you were unable to pair with other Windows 10 PCs. On the other hand, if you were able to see it, then proceed to the next troubleshooting steps below.

Option 2 – Check if Bluetooth is on

The next thing you have to do is to check if Bluetooth is turned on. As you know, the Surface Dial connects to your computer using Bluetooth and so you need to check if it’s really on or not. Aside from that, you also have to verify pairing.

• Tap the Win + I keys to open Windows Settings.
• Next, select Devices from the menu and click on Bluetooth.
• After that, make sure that the toggle switch for Bluetooth is turned on.
• Now all you have to do is to verify pairing by pressing and holding the pairing button located beside the batteries and then wait for a few seconds until the Bluetooth light begins to flash.
• Then go back to the Bluetooth section and click on Bluetooth or other devices.
• From there, click on Add Bluetooth and select Surface Dial.
• Follow the next instructions on the screen and click on Done once everything is completed. That should fix the problem.

Option 3 – Check if Surface Dial is connected to another PC

If you think that connecting a Bluetooth device to two different PCs at the same time is wise, then think again as it does not really bode well for the overall user experience. Thus, you need to disconnect the Surface Dial from the system that you are currently using. On the other hand, if everything fails, then it’s most likely that the Bluetooth adapter is the one at fault. So you may have to get a third-party device that connects to your system via USB and then see if it works or not.

The error 0x0000001 also known as APC_INDEX_MISMATCH is one of the fatal errors that users encounter upon starting their computers. This error appears when there is a sequence mismatch in the driver or system file when it is disabling or re-enabling Asynchronous procedure calls. The mismatch happens maybe because of a virus or malware attack, not shutting down your computer properly and incomplete installation of the system files. There are many ways to fix this error. The easiest way is to download a repair utility program. The use of these programs perfectly fits those that are not so technical. All you have to do is download the program and install it on your computer. As soon as it is installed, the program will now scan and diagnose your computer for any errors. After it identifies the errors, it will then repair your PC through either manual or automatic tools. To those who are techie and enjoy the manual resolution, you may take advantage of Microsoft’s analyze debug extension which tells you the cause of the error. After determining the cause then you can now start fixing the error. Check if Hardware is functioning properly. If the cause is due to a hardware malfunction, you will have to make sure that all the pieces you are using are working. All the wires should be attached to their respective ports. Not only that, but you also must make sure that before installing the hardware, it is compatible with the Windows version that is installed into your computer. Use Compatible software. If the problem was caused by software or a driver, you can uninstall and reinstall it. Always make it a rule that whenever you install a program or new software to your computer, make sure it is compatible with your operating system and never skip a step during the installation process. You also have to see to it that the program you are installing does not contain any viruses, malware, or spyware that can be harmful to your computer. Update your Drivers Regularly. In most cases though, the cause of the APC_INDEX_MISMATCH error are outdated device drivers. To resolve this, you will have to go to your Control Panel then look for Device Manager. As soon as you are in the Device Manager window, you can now see the different devices running on your computer. You right-click on each device and check the Properties.  In the Properties window, click on the Driver Tab and look for the date when it was last updated. You can then go to the manufacturer’s website and compare the dates. For a new Windows operating system, you no longer have to go to the manufacturer's website though. All you have to do is click on Update Driver and it will automatically search for updates online. Use a Genuine Operating System. There are also cases where the 0x0000001 error won’t allow you to access your computer. In this case, we have to suspect that the problem could be in your Operating system. To resolve this, you can reinstall your Operating System or update your current operating system. Only use a genuine licensed Windows Operating System because this will not only protect you from Malware and Viruses but it allows you to get all the recent update available from Microsoft. Update your Windows 10 regularly by going to Settings > Windows Update > Check for Updates. You may also turn on the Automatic Update by going to the Advanced options is found on the Windows Update Page. You can always get help online but it really helps to know the basics and determining the root cause of the error.

What is Active History? A new feature has been introduced in Windows 10 that allows users to stay connected to their tasks across their devices. This new feature is called “Windows Timeline” and using this feature, users could continue their tasks all over their Windows 10 computers as well as on devices that run Android and iOS as well. This new feature was included in Microsoft Launcher and Microsoft Edge on Android devices as well as in Microsoft Edge for iOS devices. In order for the feature to work, you have to send either Basic or Full data and diagnostics of your computer to Microsoft which would sync it all over your devices with the help of the cloud. And now since all your data is stored on your Windows 10 computer and with Microsoft under your account, it is easier for you to access the back and start where you left off. This kind of option is called Active History. In this post, you will be guided on how you can permanently disable Active History using either the Windows Registry or Group Policy. Before you go on further, it is recommended that you create a System Restore Point first in case anything goes wrong. This is a precautionary measure you must take so that you can easily undo the changes you’ve made. After creating a System Restore Point, proceed to the given instructions below.

Option 1 – Disable Active History via Registry Editor

• Tap the Win + R keys to open the Run dialog box and type in “Regedit” in the field and hit Enter to open the Registry Editor.
• Next, navigate to this registry key: ComputerHKEY_LOCAL_MACHINESOFTWAREPoliciesMicrosoftWindowsSystem
• From there, check if you can find a DWORD named “PublishUserActivities”. If you can’t find this DWORD, just create one with the same name and make sure that the base is selected to Hexadecimal.
• After that, double-click on the DWORD and change its value from 1 to 0 to disable Active History.
• Restart your computer to apply the changes you’ve made successfully.

Option 2 – Disable Active History via Group Policy Editor

Note that this second option won’t work if you are using the Home edition of Windows 10. This is because the Group Policy Editor does not come with Windows 10 Home. So if you are not using Windows 10 Home, follow the given steps below.

• Tap the Win + R keys to open the Run box.
• Then type in “gpedit.msc” in the field and hit Enter to open the Group Policy Editor.
• Next, navigate to this path: Computer ConfigurationAdministrative TemplatesSystemOS Policies
• After that, double click on the configuration listing named “Allow publishing of User Activities” to open the configuration page which has the following description:

“This policy setting determines whether User Activities can be published. If you enable this policy setting, activities of type User Activity are allowed to be published. If you disable this policy setting, activities of type User Activity are not allowed to be published. Policy change takes effect immediately.”

• Now you have to select Disabled or Not Configured if you want to disable Publishing of User Activities or Enabled to Enable Publishing of User Activities depending on your preferences.
• Next, click OK and exit the Group Policy Editor and then restart your computer to successfully apply the changes made.

Microsoft’s initial Windows 11 hardware requirements were not really well received by users and they were not really clearly represented from the start making a lot of potential customers slowly drift away from the hype. It seems that Microsoft has acknowledged this since they have changed their tune about system hardware requirements for the upcoming Windows 11. It seems that Windows 11 will be able to be officially installed on unsupported computers but with a little inconvenience.

What is a catch?

Windows 11 will still have the same hardware requirements and if the PC meets them, that computer will be officially supported, other ones (any that can run Windows 10) that do not meet system requirements can still run Windows 11 but the system will have to be clean installed. So no upgrade option for old computer users, just a clean install. This means of course that you will need to download the ISO image and make a bootable USB in order to install it. Also since you will be doing a clean install do a backup of the hard drive since it will need to be formatted. Also, Microsoft has stated that with unofficially supported PC some driver updates might not be delivered leaving you with either older driver versions or relying on your hardware manufacturer on them. This is still not confirmed by Microsoft, just stated as an option. We will see how it goes.

Conclusion

It is very good that Microsoft has reconsidered its system requirements and will not stubbornly push its initiatives over the top requirements allowing even older computers to install new OS. I am sure over time lot of users will upgrade their hardware and drive into officially supported waters, but it is good that they will be able to use new OS on their current hardware.

If you are trying to update or upgrade your Windows 10 computer using the Windows Update and suddenly an “Error 0x800f0900” appears, then you’ve come to the right place as this post will help you resolve this Windows Update issue. When you encounter this error, you will see the following error message on your screen:

“There were problems installing some updates, but we’ll try again later. If you keep seeing this and you want to search the web or contact support for information, this may help: 2018-03 Cumulative Update for Windows 10 Version 1709 for x64-based Systems (KB4088776) – Error 0X800F0900”

This kind of Windows Update error is most likely caused by some corrupted files in the system. It is also possible that the Windows Database might have become corrupted as well. So if you are currently experiencing this problem, refer to the options given below and see which one of them works best for you.

Option 1 – Try running the DISM Tool

Running the DISM Tool 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”.

• Open the Command Prompt as admin.
• Then type in this command: 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.

After you run this tool, a log file is created at C:WindowsLogsCBSCBS.log. On the other hand, if the Windows Update client is already broken, you will be prompted to use a running Windows installation as the repair source or use a Windows side-by-side folder from a network share, as the source of the files. Although the chances of this happening are less, if it turns out to be the case, you need to run an advanced command in the DISM tool to repair a broken Windows Update. Just repeat the process above but use the following command instead:

DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:RepairSourceWindows /LimitAccess

Option 2 – Try running the System File Checker or SFC scan

The SFC scan or System File Checker is a built-in command utility in Windows that helps in restoring corrupted files as well as missing files that cause several issues in the computer like the Windows Update Error 0x800f0900. It replaces bad and corrupted system files with 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.

Option 3 – Try running the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the Windows Update error 0x80073712. To run it, go to Settings and then select Troubleshoot from the options. From there, click on Windows Update and then click the “Run the troubleshooter” button. After that, follow the next on-screen instructions and you should be good to go.

Option 4 – Perform a System Restore

You can also try to perform a System Restore as it can also help you fix the Windows Update Error 0x800f0900. You can do this option either by booting into Safe Mode or in System Restore. If you are already in the Advanced Startup Options, just directly select System Restore and proceed with the next steps. And if you have just booted your PC into Safe Mode, refer to the steps below.

• Tap the Win + R keys to open the Run dialog box.
• After that, type in “sysdm.cpl” in the field and tap Enter.
• Next, go to the System Protection tab then click the System Restore button. This will open a new window where you have to select your preferred System Restore point.
• After that, follow the on-screen instructions to finish the process and then restart your computer and check if the problem is fixed or not.

Option 5 – Reset both the SoftwareDistribution and Catroot2 folders

You have to stop a couple of services such as BITS, Cryptographic, MSI Installer, and Windows Update Services. And to do that, you need to flush the contents in the SoftwareDistribution folder. The Software Distribution folder in the Windows operating system is a folder that can be found in the Windows directory and is used to store files temporarily which might be required to install the Windows Update on your PC. Thus, it is required by the Windows Update and maintained by WUAgent. Aside from that, it also contains all the Windows Update History files and once you delete them, you will most likely lose the Update history. As a result, the next time you run the Windows Update, it may result in a longer detection time.

• Open the WinX Menu.
• From there, open Command Prompt as admin.
• Then type in the following command – don’t forget to hit Enter right after typing each one of them.

net stop wuauserv net start cryptSvc net start bits net start msiserver

• After entering these commands, it will stop the Windows Update Service, Background Intelligent Transfer Service (BITS), Cryptographic, and the MSI Installer
• Next, go to the C:/Windows/SoftwareDistribution folder and get rid of all the folders and files thereby tapping the Ctrl + A keys to select them all and then click on Delete. Note that if the files are in use, you won’t be able to delete them.

After resetting the SoftwareDistribution folder, you need to reset the Catroot2 folder to restart the services you just stopped. To do that, follow these steps:

• Type each one of the following commands.

net start wuauserv net start cryptSvc net start bits net start msiserver

• After that, exit Command Prompt and restart your computer, and then try to run Windows Update once more.
