On sept 9 this year I got 9 patches to be installed in Windows Update - as usual most were security patches, so I accepted download and installation. This required a reboot.
At reboot I got BSOD c000021a, but at the next start I could start Startup Repair. Eventually it found the root cause "A patch is preventing the system from starting".
I found advice how to get rid of the failing update(s) (only topic 6 in this forum
gave a sufficient answer) and hence could work again.
Later in my session Windows Update again offered these updates and I tried it once more. This time Windows Update set a restore point which allowed me at the - again I got a BSOD at reboot - to use the Restore point.
The patches offered were KB3069114, KB3086255, KB3084135, KB3087038, KB3092627, KB3087039, KB3074543 and KB3083324. Even after hiding the last one (some sources considered it harmful) I get this darn BSOD.
But after restoring again and running now the third session, Windows Update claims "Windows is up to date" with the details:
Most recent check for updates: Yesterday at 17:37
Updates were installed: 2015-09-10 at 12.58 (failed) - the history shows all my attempts to install 3 times.
So the question is: Have the patches from sept 8, 2015 been withdrawn?
Or does this darn BSOD come back?
