What to do if Windows 10 Disk Management is not working
The Disk Management tool in Windows 10 is a built-in tool that contains a user interface used to manage disk partitions to administrators of the computer. There are lots of instances when you have to change the size of the hard disk partition or reduce the size and so on. This is where the Disk Management tool comes in. It’s useful as the command line interface can be quite confusing and risky for some users. However, there are cases when this tool stops working. A proof of this the reports submitted recently by some Windows 10 users. Based on the reports, the Disk Management does not load or respond. If you are having the same problem, read on as this post will give you some suggestions on what you can do to resolve the problem.

Option 1 – Try restarting the Disk Management Service

  • Tap the Win + R key combination to open the Run dialog box.
  • Then type “services.msc” in the field and hit Enter or click OK to open the Windows Services Manager.
  • Next, scroll down in the service list until you see the Virtual Disk Service. Double click on it to open and then select Automatic.
  • Click on Apply and OK to save the changes made.
  • If it hasn’t started yet, you can just click on the Start button to start the Service. The Virtual Disk service provides management services for disk, volumes, file systems as well as storage arrays.
  • Now save all the changes you’ve made and restart your computer. Then check if you can now use the Disk Management tool without any problem.

Option 2 – Try using 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 with good system files that might be causing some issues with the Disk Management tool. To run the SFC command, follow the steps given below.
  • Boot your PC into Safe Mode.
  • 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 using the DISM tool

Aside from the System File Checker, the DISM tool can also help you resolve the issue with the Disk Management tool. It helps in restoring the health of your computer.
  • Open the Command Prompt as admin.
  • Then type in this command: Dism /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 4 – Try using Diskpart and Fsutil

If both the System File Checker and DISM tool didn’t work, you can use command-line tools like diskpart and fsutil. These command-line tools are powerful but you need to be careful especially if you’re not that familiar with using them. However, it’s recommended that you have somebody who knows if you’re really inexperienced with this kind of stuff.

Hard drive shows wrong free space
If you are using your computer and you notice that Hard drive shows high space utilization even if you only have a few applications installed on your computer, then you’ve come to the right place as this post will guide you on what you can do to sort this problem. Upon noticing the odd state of your hard drive and you check the actual volume that’s occupied by the apps in your drive and you see that they are not really occupying a lot of space. This kind of issue could indicate that your hard drive is not showing the correct value for the free storage space of the drive-in your Windows 10 computer. This kind of problem could be passed off as a system bug, however, it could also be a serious problem. In fact, as you are aware, there are hidden folders and files in your computer that could be occupying space and since most of them are associated with system applications, you might not realize it unless you thoroughly check the folders.

The most common causes of the issue are as follows:

  1. The system information folder might be utilizing a lot of space. If you wonder where the information for the system restore points is stored, they are stored in the system information folder which in turn is stored in the drive as a hidden file.
  2. An issue with system maintenance could cause the problem.
  3. Malware or some other software might have created an undetectable hidden file.
  4. Space could be occupied by the trashbin folder.
  5. These hidden files could occupy significant space in the folder, thus slowing down the system and impacting its performance. If you face this issue, try our suggestions and see if they help you.
  6. Run ChkDsk
  7. Clear all Junk files
  8. Reduce the space occupied by the system restore points
  9. Run the System Maintenance troubleshooter

Option 1 – Run CHKDSK utility to check the drive for errors

When it comes to some issues concerning the hard drive or removable devices, there is a utility in Windows that might help which is called “chkdsk”. To use it, follow the steps below.
  • Tap the Win + S keys to open the Search box.
  • Then type “command prompt” in the field and from the search results that appear, right-click on Command Prompt and select “Run as administrator”.
  • After opening an elevated command prompt, copy and paste the following command and hit Enter:
CHKDSK [volume [[path] filename]] [/F] [/V] [/R] [/X] [/C] [: size]]
Note: In the command given above, “[/F]” will try to fix the system errors while “[/R]” will be the one to fix the bad sectors.
  • Now if you are prompted to run CHKDSK after your reboot your PC, just tap Y and reboot your PC.
  • If CHKDSK is not able to find any errors, tap the Win + E keys and navigate the access window. From there, right-click on the concerned drive and click on Properties.
  • After opening Properties, click on the tab Tools and then click on the “Check” button under the Error-checking section.
  • Wait until the process is completed and then restart your computer.

Option 2 – Try to delete the temporary files

The error could be caused by some temporary or junk files in your computer and so you need to clear them up to fix the problem. You can achieve that using the Storage Sense feature.
  • Open Setting > System > Storage from the WinX Menu.
  • From there, you will see a list of all the local and connected storage devices along with the details on the free space. Make sure that Storage Sense is on.
  • Next, find a link that says “Free Up Space” and click it to open.
  • After that, a screen which is the built-in program in Windows 10 will appear and will scan your computer for the following junk files so you can free up disk space: 
    • Windows Upgrade Log Files
    • The system created Windows Error Reporting Files
    • Thumbnails
    • Temporary Internet Files
    • Previous Windows Installation Files
    • Delivery Optimisation Files
    • DirectX Shader Cache
  • Choose the files you want to get rid of and then click on the remove files option. Note that you’ll have an idea of the total size as you select any of the junk files listed above.
  • Now go to the “Free Up Space Now” section and click the Clean Now button. This will get rid of all the temporary or junk files in your computer and should hopefully fix the error.

Option 3 – Try to reduce the space occupied by the system restore points

In case you don’t know, system restore points actually occupy a significant space in your computer which is stored in the System Information folder. Thus, you need to check the size of this folder and unhide the folders and files and then click on the folder. The size of the folder should be displayed in the right pane of the window. To fix the storage space problem, you could delete all the old System Restore Points as well as Previous versions of files or you could also restrict the disk usage of the System Restore points.

Option 4 – Try to run the System Maintenance troubleshooter

The problem could also be caused by the System Maintenance and to fix it, you have to run the System Maintenance troubleshooter by following these steps:
  • In the Windows Search bar, type “control panel” and double click on Control Panel from the search results.
  • Next, go to this path: Control PanelAll Control Panel ItemsTroubleshootingSystem and Security.
  • After that, click on the System Maintenance troubleshooter to run it.
  • Once the process is completed, restart your computer.

Different types of computer viruses
Computer viruses are malicious applications that have the ability to self replicate and spread over the system and various devices, just like viruses in organisms. We all know that computer viruses are bad and that you should avoid them however you can. So in this spirit, we are taking a deeper dive into what kind of viruses exist and how they function.

viruses types1. File-infecting Virus

A virus that attached itself to an executable program. It is also called a parasitic virus which typically infects files with .exe or .com extensions. Some file infectors can overwrite host files and others can damage your hard drive’s formatting.

2. Macro Virus

This type of virus is commonly found in programs such as Microsoft Word or Excel. These viruses are usually stored as part of a document and can spread when the files are transmitted to other computers, often through email attachments.

3. Browser Hijacker

This virus targets and alters your browser setting. It is often called a browser redirect virus because it redirects your browser to other malicious websites that you don’t have any intention of visiting. This virus can pose other threats such as changing the default home page of your browser.

4. Web Scripting Virus

A very sneaky virus that targets popular websites. What this virus does is overwrite code on a website and insert links that can install malicious software on your device. Web scripting viruses can steal your cookies and use the information to post on your behalf on the infected website.

5. Boot Sector Virus

These viruses are once common back when computers are booted from floppy disks. Today, these viruses are found distributed in forms of physical media such as external hard drives or USB. If the computer is infected with a boot sector virus, it automatically loads into the memory enabling control of your computer.

6. Polymorphic Virus

This virus has the capability to evade anti-virus programs since it can change codes every time an infected file is performed.

7. Resident Virus

A resident virus stores itself on your computer’s memory which allows it to infect files on your computer. This virus can interfere with your operating system leading to file and program corruption.

8. Multipartite Virus

A type of virus that is very infectious and can easily spread on your computer system. It can infect multiple parts of a system including memory, files, and boot sector which makes it difficult to contain.

Can’t drag and drop files or folders
Why Can’t drag and drop files or folders happens? In case you don’t know, there is a feature in Windows 10 called drag and drop that can help you move or copy files or even folders from one location to another. This feature is useful and can help you move or copy folders and files easier and quicker. However, if you encounter some problem while using this feature, worry not for this post will guide you on what you can do to resolve the problem. There are several suggestions you can check out to fix the problem. You can try to simply tap the Esc key or you could also troubleshoot the problem in a Clean Boot State. Aside from that, changing the drag height and width or disabling the User Account Control via Registry Editor might also help. For more details, refer to the instructions laid out below.

Option 1 – Try to tap the Esc key

According to some users who experienced the same dilemma, by simply tapping the Esc key, they were able to resolve the problem. All they did was tap the Esc key before they drag and drop the folder or files. Thus, you can try doing the same thing as it might also work for you. After you tap the Esc key, you have to check all the background applications and if you see some that could be related to the hotkeys or keyboard, you might have to disable or remove them. Once done, check if the problem is fixed or not.

Option 2 – Try troubleshooting the problem in a Clean Boot State

There are some instances that some conflicting programs installed in your computer might be the reason why you’re having trouble using the drag and drop feature in Windows 10. To identify which program is causing the problem, you need to put your computer in a Clean Boot State. To do so, follow the steps below.
  • 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” checkbox 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 to configure Windows to use the usual startup, just simply undo the changes.)
  • From there, start to isolate the problem by checking which one of the programs you installed recently is the root cause of the problem.

Option 3 – Try changing the drag height and width

The next thing you can do to resolve the issue is to try changing drag height and width by following these steps:
  • Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
  • Next, navigate to this registry key: HKEY_CURRENT_USERControl PanelDesktop
  • From there, choose to modify both the “DragHeight” and “DragWidth” located on the right pane.
  • After that, change the value to a very high number. Note that these values are nothing but pixel size to drag and drop folders or files.

Option 4 – Try disabling the User Account Control or UAC via Registry Editor

  • Tap the Win + R keys to launch the Run utility and type “Regedit” in the field and then tap Enter to open the Registry Editor.
  • After that, navigate to this registry key: HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesSystem
  • From this path, modify the value of “EnableLUA” from 1 to 0. This should disable the UAC in your Windows 10 computer.

Microsoft project Volterra

Microsoft will soon offer 4 CPU computer specifically aimed at developers and its name is Volterra. The machine as stated will come with 4 processors but the strange thing is that they will be ARM-based instead of x86.

CEO of Microsoft, mister Satya Nadella has introduced the product and Microsoft has released a youtube video promoting it.

https://youtu.be/yICVNta8jMU

The computer system will have Qualcomm's NPU or built-in neural processing unit to use AI's power to help developers write and produce better and faster code. The sad news is that besides processors used there is no other information on other components that will go into this system.

As seen in the video, the computer reminds me a lot of the apple MAC mini with its size and design, and as stated it is made from recycled plastic which in our opinion will bring the price under $1000.

Microsoft has not provided an official price tag for Volterra, but our hope is that it will be more affordable than building your own development PC. Also, there was nothing said about computer availability, we suspect that the selling model will be typical Microsoft one with first models available only in the USA and moving forward slowly opening it to other markets.

Volterra specifications

As previously said nothing except the number of CPUs and their type has been officially said but we managed to get some information about some other specific things not including its inside components.

microsoft volterra

The unit will have a fan inside of it for cooling purposes and better performance and that is what was officially stated by Microsoft. On the outside, it is known that the computer will have three USB-A ports, a mini DisplayPort, and an ethernet input. All of these will be positioned on the back of the device, on its left side there will be two USB-C ports.

The unit itself will be running on Windows 11 but it was not disclosed anything about the version, we presume since this is a model aimed for professional use that it will come with Windows 11 PRO version.

Currently available tools for ARM

Since this product is aimed at developers logically support for developing software is a must-have and at the time of this writing software that will come and that will run on Volterra is:

  • Visual Studio 2022
  • Visual Studio Code
  • Visual C++
  • Modern .NET 6 & JAVA
  • Classic .NET
  • Windows Terminal
  • Windows Subsystem for Android
  • Windows Subsystem for Linux

Conclusion

Once MAC studio has been released it showed that specific builds have their audience and can be sold for less of a price than full-fledged custom-made workstations. There is no doubt that Microsoft Volterra will find its audience but will that be enough to have more versions of this compact computer only time will tell.

  • 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 2 – Try disabling the Proxy server

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 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 3 – Use the Google Public DNS

You might want to change your DNS to Google Public DNS as it could also help you in fixing the ERR_CERT_COMMON_NAME_INVALID error in Chrome. To do so, follow the steps below.
  • The first thing you have to do is right-click on the network icon in the Taskbar and select Network and Sharing Center.
  • Next, click on the “Change Adapter Settings” option.
  • After that, search for the network connection that you are using to connect to the internet. Note that the option might be “Wireless Connection” or “Local Area Connection”.
  • Right-click on your network connection and click on Properties.
  • Then select the new window to choose the “Internet Protocol 4 (TCP/IPv4)” option.
  • After that, click on the Properties button and click the checkbox in the new window for the option “Use the following DNS server addresses”.
  • Type in “8.8.8.8” and “8.8.4.4” and click OK and exit.

Option 4 – Try contacting the website administrator

If the first three given options didn’t work, you might want to consider contacting the website administrator especially if you’ve already determined that the issue does not occur due to a VPN or proxy server that you’re using. This option can be quite tricky since you won’t be able to submit a contact form since you’re banned from accessing the website but you can contact the admin via the form section if available.

To resolve the 0x8007002C-0x4001E, The installation failed in the SECOND_BOOT phase error, here are some suggestions that might help.

Option 1 – Try flushing 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 flushing 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.

Option 2 – Select the Keep your files option

You can also select the option to perform an in-place upgrade and opt for the “Keep my files” option during an installation as it might make the process a lot smoother and if you need to perform a clean install, you can do so once the setup is completed.

Option 3 – Try to run the Windows Update Troubleshooter

Running the built-in Windows Update troubleshooter could also help you resolve the 0x8007002C-0x4001E, The installation failed in the SECOND_BOOT phase error. 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.

Option 4 – Try to run Microsoft’s online troubleshooter

Aside from the Windows Update Troubleshooter, you can also run the online troubleshooter of Microsoft as it can help you with Windows 10 upgrade errors.

Option 5 – Perform a clean install

If none of the options worked, you can try to clean install Windows 10. Just make sure that you have the ISO from the official Microsoft Website and then a bootable USB drive to install Windows 10 again. Take note that this will delete all the data from your drive where Windows 10 was installed previously.
