Error code 0xc0000221 typically indicates a problem with a device driver or a system file. It often occurs during the Windows startup process and can prevent your computer from booting up properly.
Here are some steps you can try to troubleshoot this error:
Boot into Safe Mode: Try to boot your computer into Safe Mode by pressing the F8 key during startup. This will start your computer with only the basic drivers and services, which can help you identify and fix the issue.
Check for hardware issues: If you recently added new hardware to your computer, such as a printer or scanner, try removing it and see if that resolves the issue. You can also run a diagnostic test on your hardware components to check for any failures.
Use System Restore: If the error occurred after making changes to your computer, such as installing software or updates, you can try using System Restore to revert your computer back to a previous state.
Repair system files: Try running the System File Checker (SFC) tool, which scans for and repairs corrupted system files. To do this, open Command Prompt as an administrator and type "sfc /scannow" without quotes and hit enter.
Reinstall Windows: If all else fails, you may need to reinstall Windows to fix the error. Be sure to backup important data before doing so.
If none of these steps work, you may want to seek assistance from a professional technician or contact Microsoft support for further help.
