How to upgrade Windows 8.1 to Windows 11? This is the original "best" method and is useful if you are already inside the Windows 11 installer and see the "This PC can't run Windows 11" error.
How it works: During the initial setup screens, you can open a command prompt and add a registry key that tells the installer to skip the compatibility checks.
Steps of Upgrading Windows 8.1 to Windows 11:
- Create a Standard Windows 11 USB: Use the official Microsoft Media Creation Tool to create a normal Windows 11 installation USB.
- Boot from the USB and Start Installation: Get to the screen where you select your language and click "Install Now".
- Trigger the Bypass: When you see the screen that says "This PC can't run Windows 11", press Shift + F10 on your keyboard. This will open a Command Prompt window.
- Type the Bypass Command: In the command prompt, type the following command and press Enter: regedit
- Navigate and Create the Key:
* In the left pane, navigate to: HKEY_LOCAL_MACHINE\SYSTEM\Setup
* Right-click on the Setup folder and select New > Key. Name the new key LabConfig.
* Right-click on the new LabConfig key in the left pane, and select New > DWORD (32-bit) Value. Create two new values with the following names and values:
Name: BypassTPMCheck | Value: 1
Name: BypassSecureBootCheck | Value: 1
Name: BypassRAMCheck | Value: 1
Name: BypassStorageCheck | Value: 1
Name: BypassCPUCheck | Value: 1 - Close and Continue: Close the Registry Editor and the Command Prompt windows. You can now click the back arrow and proceed with the installation as if your PC were fully compatible.
