5 Ways to Fix Windows 10 Activation Key Not Working

Verify Your Product Key

Before diving into complex troubleshooting, start by double-checking your product key. Ensure that you have entered it correctly without any typos. The product key should match the version of Windows 10 you are using.

1. Open Settings > Update & Security > Activation.
2. Click on Troubleshoot.
3. Follow the prompts to let Windows diagnose and fix the issue.

Reactivate Windows 10 After Hardware Changes

If you’ve recently made significant hardware changes, like replacing the motherboard, you might need to reactivate Windows 10. Microsoft provides an easy way to do this, especially if your license is linked to your Microsoft account.

Steps to check and retry activation:

1. Ensure your internet connection is stable and working correctly.
2. Restart your PC to refresh the network settings.
3. Go to Settings > Update & Security > Activation and try activating again.
