I had an update from my Windows 7 computer labelled as KB971033. After this update, it slows down my computer system. And I started to get a notification that my Windows is not genuine.
This operating system was pre-installed when I bought my computer. So I really don’t know if this is genuine or not. But beforehand, I saw on my System that my Windows is already activated. How can I remove this update from windows? Help please.
