After installing KB320145 I cannot open the Start menu anymore. It appears that all standard Windows apps like OneNote, Edge, System settings, that I had pinned at the taskbar will not launch too. Fortunately all other apps and programs still work fine.
I already restored my system two times and then installed KB3201845 again with the same result.
As far as I understand KB3201845 was aimed to repair a WIFI issue. Ironically my desktop PC does not have WIFI. So, this update, that my PC did not need, broke it.
