Upgrading your Windows computer may not always go as expected as you could end up getting some error messages along the way. One of the error messages you can encounter is the “STOP 0XC000021A or STATUS_SYSTEM_PROCESS_TERMINATED” error. This error indicates that is some security issue within the Windows operating system. It could be that the system files have an issue and they have been modified incorrectly. Although this does not necessarily mean that malware is behind the modification, one of the applications you installed recently might have something to do with the problem. The application might have modified or corrupted some of the core system files. When you encounter this error, you will see a blue screen along with the following error message:

“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you. (0% complete) If you’d like to know more, you can search online later for this error: 0xc000021a”

This error pops up when a user-mode subsystem like the WinLogon or the Client Server Run-Time Subsystem or CSRSS has been compromised fatally and security can no longer be guaranteed in the system. Thus, the operating system switches to kernel mode, and Windows won’t be able to run without the WinLogon or the Client Server Run-Time Subsystem. This is why it’s one of the few cases where the failure of a user-mode service can shut down the system. To resolve the issue, here are some fixes that might help.

Option 1 – Uninstall programs you installed lately

• In the search box, type in “control” and then click on Control Panel (desktop app) among the search results.
• After that, select Programs and Features from the list which will give you a list of all the programs installed on your computer.
• From there, look for the concerned program and select it and then uninstall it.

Note: If you have downloaded the app from the Windows Store, you can simply right-click on it from the application list and then uninstall it.

Option 2 – Perform System Restore

Installing a Windows 10 upgrade is definitely not an easy task since the process is not always smooth sailing and you could encounter some errors when doing so. This isn’t unusual since there are various software configurations and hardware configurations as well as services it depends on in order to properly work. So if any of them malfunctions or becomes corrupted, it will affect the process which will result in errors like the error code 0x80300002. When you encounter this kind of Windows Update error, you will see the following error message on your screen:

“We couldn’t install Windows in the location you choose. Please check your media drive. Here’s more info about what happened: 0x80300002”

You can encounter this kind of error if there is corruption in the partition table of the drive where the installation is in progress. In addition, corruption on the Media device could also cause this problem. So if you encounter this error when running Windows Setup, read on as this post will guide you in fixing it. There are several ways to resolve this issue. The first thing you can do is to verify the compatibility between the BIOS and the installation media. You could also try recreating all the partitions as well as recreating the bootable USB drive. For more detailed information, follow the given options below.

Option 1 – Check if the BIOS is compatible with the installation media

The first thing you can do to fix the error is to check if there are any compatibility issues between the BIOS and the installation media you’re using. This is actually one of the most likely reasons why you’re getting the error since this is a complicated point for the Windows installation process. If the installation media is based on GPT, then your BIOS must be based on UEFI. So if you have your bootable media with the MBR partitioning, you need to set your BIOS to Legacy.

• In the Windows Search box, type “command prompt” and from the search results that appear, right-click on Command Prompt and select the “Run as administrator” option.
• After that, execute this command: exe /convert /allowfullOS
• Now, wait until the process is completed since you can track its process on your screen.
• Once it’s done, go to Settings > Update & Security > Advanced Startup options and from there, click on Restart Now. This will restart your computer and give you advanced options.
• Next, select Troubleshoot > Advanced Options where you will see further options including System Restore, Startup Repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Now select the “Legacy” option. This will take you to the BIOS. Boot Mode is typically available under Boot > Boot Configuration. Once you’re there, set it to Legacy and then save the changes you’ve made. After that, your computer will restart.

Option 2 – Try recreating a new bootable drive

• Insert your USB drive into your PC.
• Tap the Win + R keys to open the Run dialog box and type in “cmd” and tap Enter to open the Command Prompt. Alternatively, you can also search for “cmd” in the Cortana search box to open Command Prompt.
• Once you’ve opened CMD, type in this command to open the DISPART utility – diskpart
• After that, you should see a new black and white window that would say, “DISKPART>”.
• Next, type in “list disk” in the command line and tap Enter to see the list of all the Storage devices as well as your hard disk connected to your PC. Here, you have to identify your disk’s number.
• Type in this command where “X” is the disk number you have identified and then tap Enter – disk X
• Type in this command and hit Enter to clear the table records and all the visible data on the drive – clean
• Now you have to recreate a new primary partition of the drive so you’ll have to type in this command and tap Enter right after – create part pri
• A new primary partition has been created so you have to select it by typing this command and tapping Enter – select part 1
• Now you have to format it to make it visible to normal users by typing – format fs=ntfs quick

Note: If your platform supports the Unified Extensible Firmware Interface or UEFI, replace the “NTFS” with “FAT32” in the command on Step 10.

• After that, type in this command and tap Enter after – active
• Finally, type this command and hit Enter to exit the utility – exit
• After you prepare the image for the operating system, save it to the root of your USB Storage device.

Option 3 – Try to recreate all the partitions

If none of the first two options given above worked, then you can try to recreate all the partitions instead. All you have to do is restart the Windows installation process and wait until you get to the part that says, “Where do you want to install Windows?”. From there, you will see options like delete, format, extend, create new partitions, and many more. Now you have to select the Delete all the partitions options and then use the “New” button to create new partitions. Just make sure that you have one primary partition at least where you can install Windows 10. After that, continue the installation of Windows on the new partition. Keep in mind that when you create a new partition, it also recreates the partition table configuration which means that the chances of getting an error are very unlikely.

Since Windows 10 introduced the concept of notifications, almost any application installed on your computer sends you one. However, there are times when too many notifications can be quite annoying. Although some of them are important, most of them are not and are only getting in the way of your tasks. So if you don’t like to be flooded with tons of notifications on your Windows 10 computer, say no more as this post will help you out in disabling notifications for any apps installed. And now with the new feature in Windows 10 called Focus Assist, you will be able to manage the level of notifications that you receive. This new feature also allows you to disable all notifications except for the ones from important or priority apps. You will just have to maintain a list of priority applications or you could also disable all the notifications except for the important ones like alarms. In addition, you could also set up some automatic rules such as the Focus Assist timings which means that you can make Focus Assist enabled for a certain period of time during the day or when you are duplicating your display or playing a game and whatnot. So if there is an application that keeps on spamming you with notifications, you can just disable the notifications for that application.

To get started on disabling notifications, refer to the steps given below.

• Step 1: Go to Settings > System.
• Step 2: From there, open Notifications and actions and then scroll down to the “Get notifications from these apps” section.
• Step 3: After that, look for the application that you want to disable notifications for and click on the toggle button that corresponds to disabling notifications for that application. You could also click open to explore additional settings for that particular application.

Note: You can disable notifications or just the notification banners, your choice. Aside from that, you can also control the notification sound as well as its behavior when the computer screen is locked. What’s more, is that you can also adjust the number of notifications displayed in the Action Center or select the priority applications. As stated earlier, Windows 10 gives you control that allows you to customize every nook and cranny of the notification on your Windows 10 computer. Apart from applications, there are also other notifications-related settings that you can control including disabling notifications about tips, tricks, and suggestions as well as summary notifications from Windows Defender that you get every time you use or scan your computer.

Both the DISKPART utility and the Disk Management are useful tools in Windows 10 that manage the disk space allocation, and so on. But these tools are not without errors as you could also encounter some when you run them. Recently, some users reported getting an error that says, “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility”. Here’s the exact message of the error:

“The selected disk is not a fixed MBR disk. The ACTIVE command can only be used on fixed MBR disks.”

This kind of error only occurs when you try to activate a disk partition on a UEFI system partition. However, the command works only if your computer is based on BIOS/MBR. The UEFI method has no concept of the active partition and since you have a UEFI system, the disk type is GPT instead of MBR. To simply put it, your BIOS needs the MBR disk type while the UEFI needs the GPT disk type. To fix the “The selected disk is not a fixed MBR disk when trying to use the DISKPART utility” error, there are various potential fixes you can try. You might have to disable Secure Boot, convert the disk to MBR or fix the Boot Manager. For more instructions, follow the options provided below.

Option 1 – Disable the Secure Boot in the BIOS

Disabling the Secure Boot in the BIOS settings is definitely recommended to resolve the issue. To disable Secure Boot, here’s what you have to do:

• First, boot your computer into Windows 10.
• Next, go to Settings > Windows Update. From there, check if there is anything that you have to download and install if you see any available updates. Usually, OEMs send and update the list of trusted hardware, drivers, and operating systems for your computer.
• After that, go to the BIOS of your computer.
• Then go to Settings > Update & Security > Advanced Startup options. If you click on Restart Now, it will restart your computer and give you all the advanced options.
• Next, select Troubleshoot > Advanced Options. As you can see, this screen offers you further options including System restore, Startup repair, Go back to the previous version, Command Prompt, System Image Recovery, and UEFI Firmware Settings.
• Select the UEFI Firmware Settings which will take you to the BIOS.
• From there, go to the Security > Boot > Authentication tab where you should see Secure Boot. Note that every OEM has its own way of implementing the options so it varies.
• Next, set Secure Boot to Disabled and set Legacy Support to On or Enabled.
• Save the changes made and exit. Afterward, your computer will reboot.

Option 2 – Try converting the disk to MBR

You can try to change the File System of the drive from GPT to MBR but before you do so, make sure that you create a backup copy of your data to an external drive. Once you have that covered, follow the steps below.

• Create a bootable Windows 10 media and boot your computer from it.
• Next, click on the “Repair your computer” option on the first Windows 10 installation setup window.
• Afterward, select the operating system partition from the given options and click on Next.
• Now select Command Prompt within the System Recovery options box and execute this command to initiate the Diskpart utility: diskpart
• Then type either one of these commands to view the list of all the Disk connects or the partitions on those disks formed: list disk or list volume
• After that, execute another one of these commands depending on the command you previously entered to select the disk or partition you want to select: select disk # or select volume #
• Now execute this command to clean your drive: clean
• Finally, execute this last command to convert the selected disk or partition as MBR: Convert MBR
• Restart your computer and check if the error is fixed.

Option 3 – Try to fix the Boot Manager

• You can start by booting into the installation environment for Windows 10 from an installation media.
• After that, click on Repair your computer and on the blue screen, select Troubleshoot and then select the Advanced options menu.
• From there, select Command Prompt and once you open it, enter each one of the commands given below by sequence.
