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 of 2017, completing support for all processors will be available for Windows 10, and not earlier versions of Window.
The company then released the updates, KB4012218 and KB4012219 which for the first time had the ability to detect the hardware in systems with Windows 7 and 8,1 and stop the update by displaying the following picture:
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 he did basically was to extract all the files of the update so he could analyze them separately.
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.
By tinkering with IsDeviceServiceable(void) managed to not notify Windows Update about what CPU the machine.
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.
Patches act like scripts that you just have to run to make the necessary changes. Windows Update will continue to work just like you did before.
Caution: before applying the crack keep a copy security of the Wuaueng.dll file.
Of course, the above method may last until the next Wuaueng.dll is released by Microsoft.
