If you're part of the Windows Insider program and have encountered the error "This PC can't be upgraded to this version of Windows" while trying to install a Windows 11 update, you're not alone. This issue is particularly common among users with MSI motherboards, preventing them from installing new updates. Many users have reported being stuck at 35% during installation. The root cause often lies in an outdated cFosSpeed driver, which interferes with the update process. Fortunately, there is a straightforward solution to this problem.

In this guide, we'll walk you through the steps to resolve this error and successfully install the Windows 11 update.

Resolve "This PC can't be upgraded to this version of Windows" from the settings

Here’s how you can fix the issue quickly and efficiently:

  1. First, open the Settings app from your Windows 11 Start Menu.
  1. Next, navigate to the Windows Update section from the left-hand panel in the Settings window.
  1. Click on the Fix Issues button on the right side of the screen. This will open a new window with more details.
  1. In the new window, select the Learn More option. This will redirect you to the cFosSpeed download page in your default browser.
  1. On the cFosSpeed page, locate the latest version of the driver (currently Ver. 12.00) and click on the Download cFosSpeed button.
  1. Once downloaded, find the cfosspeed.exe file in your default downloads folder and double-click it to start the installation.

Note: If you haven’t set a custom downloads directory, the file will be in the default Downloads folder.
