Error code 0xc000021a occurs when the system is unable to start or there’s a failure in critical system processes. Normally, it would take about several seconds for the system to boot and while on the startup process, error code 0xc000021a may take place to block the system to boot up. Users will get a blue screen of death (BOSD) when this error occurs. When upgrading to Windows 10, be careful; you might encounter other error messages such as error code 8007002c.
Error CausesThere are several reasons why error code 0xc000021a occurs. It is important to have a full understanding of what caused the blue screen of death before attempting to fix the error by yourself. See below for a few common causes:
• Computer malware has infiltrated your device.
• Important files such as Winlogon.exe and Csrss.exe are damaged. Winlogon.exe file is responsible for handling the login and logout processes while Csrss.exe is a vital part of Microsoft Client or Server ‘Runtime Server Subsystem’. Once one of these files is damaged or deleted, a stop error will occur.
• When there are mismatched system files installed or system upgrading process failed or still incomplete.
• Premature unloading of Wbemprox.dll
• Newly installed third-party software is not compatible with the operating system.
• There are corrupted, outdated, or incorrectly configured device drivers.
• There’s insufficient space in the system partition. Once the system partition is full, certain errors such as error code 0xc000021a will manifest.
• Windows registry is corrupted or damaged due to a software or system change. This means there are registry entries that are not cleared after uninstalling an application.
In fixing error code 0xc000021a, you might want to try and manually do so. Manual repair methods can give users effective and efficient solutions, addressing the root problems in relation to Windows error codes. Once the manual repair method is correctly implemented, users will be able to resolve issues immediately. However, there might be instances when a Windows professional is needed. In such cases, seek help from a certified Windows expert or you might want to consider using an automated tool whenever necessary.

“Windows could not configure one or more system components. To install Windows restart the computer with error code 0xc1900101-0x30018.”When you check on the Windows 10 rollback log, you will see a part with the “iisetup.exe” that’s related to the abort. Usually, the upgrade process completes over 50% and gets stuck and then rolls back later on and generates the error logs. This kind of error, in most cases, appears during the upgrade of Windows 10 and is related to the Internet Information Services or IIS in Windows 10. For some unknown reason, it restricts the installation or the upgrade which causes the error to appear. To fix the “Windows could not configure one or more system components” error, you can try to remove the IIS from the Windows Features or rename the “inetsrv” folder. You could also move all the folders related to IIS to another drive. For more details, refer to the options provided below.
“SYSTEM [DRIVER] USB AUDIO DEVICE An audio stream is currently in use [DRIVER] Legacy Kernel Caller.”Step 2: The next thing you have to do is remove all the external hardware connected to your computer. In this step, you have to disconnect external hardware from your computer. Based on reports from users who experienced the same issue, the “TV card” is the culprit so make sure you remove that one. Once you’ve removed it, open Command Prompt and run the “powercfg –requests” command again and you’ll see that the “Legacy Kernel Caller” will no longer be on the list. In addition, your computer will get into its regular sleep mode once the hardware is removed. Once you do that, the driver gets hung and won’t release the power request despite being used. Step 3: Try using the request override option The powercfg command also offers a request override option which allows users to disable the requests from applications and services to wake the computer from sleep mode. To run this command, simply open Command Prompt with admin privileges. After you open Command Prompt, type the following command and hit Enter to disable requests from applications and services that causes the computer to wake from sleep state.
Powercfg -requestsoverride Driver "Legacy Kernel Caller" SystemStep 4: Check the streaming and media applications You also have to check if your computer is running an audio or video service in the background. In such cases, your computer won’t be able to go to sleep mode if these services are running in the background. You might have noticed that when you play a video or audio, your computer never goes to sleep. And if you have put it to sleep in between watching the video, then it’s probably why your computer is waking up. Thus, you have to stop these services. Step 5: Check the devices that can wake your computer If you didn’t see the Legacy Kernel Caller in the result after you execute the ”powercfg –requests” command, then you can try to execute the following command instead.
powercfg –devicequery wake_armedAfter you enter this command, it will give you a list of all the devices that can wake your computer. So if there is anything other than the mouse, keyboard, touchpad, you have to check the power configuration of that device. To do that, go to the Device Manager and disable the device’s “Allow this device to wake the computer” option in its Properties Step 6: Check the Sleep Advanced Settings
