Once the repair process completes, try logging in to your account and gain access to the desktop and your other apps and data.

Check Your Disk for Errors

Bad hard disk sectors can cause an error code 0xc0000001 and prevent you from logging in. To resolve the problem, you can run the ChkDsk utility to scan for and fix bad disk sectors.

Clean Boot Windows 11

Another potential cause of the BSOD error is a corrupt app or service running during startup. To narrow down the problematic app or service, you can perform a clean boot of Windows 11.

Once you do a clean boot, if the issue is no longer there, you’ll have a good point of reference for where to start troubleshooting.

The troubleshooting can be tedious, but if the clean boot works, you can start enabling one app or service at a time until you come across the one causing the problem.

Use System Restore

If the options above don’t resolve the error, your next best bet is to recover with a Restore Point using System Restore. This will allow you to revert your system to an earlier working state when the error wasn’t affecting your PC.

If you are unable to get to your desktop, you can boot into Safe Mode and use System Restore from there.

Reset Your PC

If you are unable to use System Restore or don’t have a restore point to revert to, you’ll need to reset your Windows 11 PC. Resetting your PC allows you to keep your personal files but removes apps and reinstalls Windows.
