Using System Restore To Fix Error Code 0xC000021A
System Restore is a built-in feature in Windows that allows users to create restore points – snapshots of the computer’s settings and system files. These restore points can be used to revert the system back to a previous, functioning state. When encountering Error Code 0xC000021A, utilizing System Restore can be an effective solution.
To begin, access the Advanced Startup Options by restarting the computer and repeatedly pressing the F8 key. From there, select “Repair Your Computer” and choose “Troubleshoot” > “Advanced options” > “System Restore”.
Next, select the restore point that was created prior to the occurrence of the error and follow the on-screen instructions to initiate the restoration process. This process may take some time and will result in the computer restarting multiple times.
System Restore is a reliable method for resolving Error Code 0xC000021A, as it reverts any system changes that may have contributed to the error. However, it is important to note that any data or programs installed after the selected restore point will be lost, so it is essential to back up any important files before proceeding with System Restore.
Repairing Corrupted System Files To Resolve Error Code 0xC000021A
When encountering error code 0xC000021A, corrupted system files can often be the culprit. These files are essential for the smooth operation of your computer, and any damage or corruption can lead to various issues, including the mentioned error code.
To fix this problem, there are a few steps you can take. First, you can use the System File Checker (SFC) tool, which is a built-in Windows utility that scans for corrupted system files and replaces them with healthy copies from the Windows cache. To run the SFC tool, open Command Prompt as an administrator and type ‘sfc /scannow’ before pressing Enter.
If the SFC tool doesn’t resolve the issue, you can try running the Deployment Image Servicing and Management (DISM) tool. This tool helps repair Windows images and enables the SFC tool to do its job more effectively. Open Command Prompt as an administrator and enter ‘DISM /Online /Cleanup-Image /RestoreHealth,’ then press Enter.
If both these methods fail, you may need to consider reinstalling Windows or seeking professional help to assist you in resolving the issue with your computer’s corrupted system files.
Updating Drivers As A Solution For Error Code 0xC000021A
