Re: I recently noticed
Don't be too quick to celebrate, I was in the same state, until recently, with Windows 10 repeatedly failing to do any full "feature" updates - always failing after a reboot complaining it couldn't find an EFI component that was definitely installed in the path it was searching. However, when I upgraded my graphics card I found that I couldn't install the required drivers from nVidia because my Windows was too old.
I have ended up doing a fresh install on top of my old windows and losing all my programs and settings as a result. Oh and I'm no longer activated - Thanks Microsoft, what a way to win more custom!
