Using the Registry Edit Method to upgrade Windows 10 to Windows 11 for free involves modifying certain registry keys to bypass the standard hardware checks that Windows 11 setup performs.
If you still want to proceed, here are the general steps about upgrading Windows 10 to 11 for free:
1. Open Registry Editor:
- Press Win + R, type regedit, and press Enter.
2. Navigate to the Key:
HKEY_LOCAL_MACHINE\SYSTEM\Setup
3. Create or Modify the Key:
- Create a new key named MoSetup if it doesn't exist.
- Inside MoSetup, create a new DWORD (32-bit) value named AllowUpgradesWithUnsupportedTPMOrCPU.
- Set its value to 1.
4. Proceed with the Upgrade:
- Run the Windows 11 installation media or upgrade process. The setup should now bypass the TPM and CPU checks.
