Fixes for Error 0xd000a002

This error can occur due to various reasons including system updates, software glitches, or corrupted Windows security files. Here’s how to address it:

1. Restart Your Device: Sometimes, a simple restart can fix temporary glitches affecting the system’s operations.
2. Update Windows: Ensure your device is up-to-date with the latest Windows updates. Go to Settings > Update & Security > Windows Update and click on ‘Check for updates’.
3. Reset Your PIN: Since you’ve already tried resetting your PIN without lasting success, try removing it entirely and then adding it again:
   • Go to Settings > Accounts > Sign-in options.
   • Click on ‘Windows Hello PIN’ and select ‘I forgot my PIN’.
   • Follow the prompts to reset your PIN and then restart your computer to test if the issue persists.
4. Enable TPM in BIOS: If your laptop supports TPM 2.0 but it’s disabled, enabling it may resolve the issue. Access your BIOS settings during boot-up (usually by pressing a key such as F2, F12, Del, or Esc, depending on your device manufacturer):
   • Navigate to the security tab or similar in your BIOS menu.
   • Find the TPM option and ensure it is enabled. If it’s disabled, enable it, save the changes, and exit the BIOS.

   Note: The exact steps can vary depending on your laptop’s model and manufacturer, so refer to your laptop’s user manual for specific instructions.

5. Scan for Malware with Gridinsoft Anti-Malware: Malware can sometimes cause system errors and disrupt normal functions. Run a full system scan using Gridinsoft Anti-Malware to detect and remove any malicious software that could be causing the PIN error:

Navigate to Settings > Update & Security > Troubleshoot > Additional troubleshooters and select ‘Windows Hello’ to start the troubleshooter.
7. Check for System File Corruption: Corrupted system files can cause unexpected issues with user logins. Open Command Prompt as an administrator and run sfc /scannow to scan for and restore corrupted system files.
8. Restore System Health: If the SFC scan does not resolve the problem, you can try using the Deployment Imaging and Servicing Management (DISM) tool to repair the Windows system image. Run the following command in an elevated Command Prompt: DISM /Online /Cleanup-Image /RestoreHealth.
