How to Fix Windows Error Code 0xc0000221

Fixing the Windows error code 0xc0000221 involves several steps. Here’s a detailed guide to help you through the process:

1. Restart Your Computer: Sometimes, a simple restart can fix the issue. If the error was caused by a temporary glitch, rebooting might resolve it.
2. Check for Hardware Issues: Run hardware diagnostics to ensure that your hard drive and RAM are functioning properly. Many manufacturers offer built-in diagnostics tools for this purpose.
3. Use System File Checker (SFC): The SFC tool can scan and repair corrupted system files. To use it:

• Open Command Prompt as an administrator.
• Type sfc /scannow and press Enter.
• Wait for the scan to complete and follow any on-screen instructions to fix detected issues.

2. Update or Reinstall Drivers: Check for driver updates through Device Manager or the manufacturer’s website. If updating doesn’t work, consider uninstalling and reinstalling the problematic drivers.
3. Perform a System Restore: If you’ve recently installed new software or updates, performing a system restore to a previous point when your system was functioning correctly can help. Access System Restore from the Control Panel or through the recovery options in Windows.
4. Reinstall Windows: As a last resort, if none of the above solutions work, you might need to perform a clean installation of Windows. Back up your data before proceeding with this option, as it will erase all your files and applications.
