Microsoft As it is known has blocked the availability of updates to systems with Windows 7 and 8.1 devices running a new generation processor.
The company announced the change in January 2017, adding support for all processors will be available for Windows 10, not earlier versions of Windows.
The company then released the updates, KB4012218 and KB4012219 which for the first time were able to locate the hardware on Window 7 and 8,1 systems and stop updating by displaying the following image:
Let's see what we can do with it…
The zeffy user from GitHub has decided to look at how Microsoft manages to lock up installation updates. With a closer look he noticed that locking is at the level of the operating system.
What he did then was:
Download Patch KB4012218 from Microsoft.
It extracted the contents of the MSU file using expand command line tool. What it essentially did was extract all of the update files so that it could analyze them individually.
The files were too many and then used PowerShell to filter the files with anything starting with "wu" to find the ones related to Windows Update.
While reading the code and searching for the calls he discovered wuaueng.dll, both of its functions: sCPUSupported (void) and IsDeviceServiceable (void).
Having found the cause, he should develop a solution to bypass the Windows Update block.
Teasing IsDeviceServiceable (void) a bit, Windows Update was not notified about what CPU the machine is using.
So the solution is a crack that "fixes" the dll. Zeffy uploaded patched files (32-bit and 64-bit) for Windows 7 and Windows 8.1 on his GitHub page. The source code is also available and you can check it.
The patches they work like scripts that you just have to run to make the necessary changes. Windows Update will continue to work exactly as before.
Caution: before applying crack keep a backup of the Wuaueng.dll file.
Of course, the above method may last until the next Wuaueng.dll is released by Microsoft.
