How to install Windows 7/8.1 updates on Kaby Lake and Ryzen PCs

2 minute read

One of Microsoft’s latest decisions involved the company’s announcement that owners of Windows 7 and Windows 8.1 CPUs couldn’t use the newest processors, such as Intel’s Kaby Lake or AMD’s Ryzen, unless they run Windows 10.

No more updates for Windows 7 and 8.1

A computer upgraded to the newest chips but still running Windows 7 or Windows 8.1 is not going to get updates anymore. Microsoft explained in a note that the “PC uses a processor that is designed for the latest version of Windows”, suggesting that users should upgrade to Windows 10.

The patch to bypass the OS limitation

GitHub user zeffy seems to have found a solution to this restriction by analyzing the KB4012218 patch shipped by Microsoft a couple of days ago and found that it was responsible for implementing the limitations blocking Windows Update on CPUs running on the latest chipsets.

After investigating the files, zeffy found out that the dynamic link library wuaueng.dll has to be patched in order to remove the limitation. He has since then developed a script that can be used on Windows 7 and Windows 8.1 running 32-bit and 64-bit installations of the OS. Zeffy made the files available on his GitHub page. The script works by patching a system file that you’re strongly recommended to back up before proceeding.

This is only a temporary solution as Microsoft can and probably will introduce the restriction again anytime the company pleases. In other words, users might have to re-apply the patch later on though more modifications might be necessary if Microsoft chooses to block the method presented above.
