windows 10 updates are defenitly a mess, here is my observations from test rig.
You can say that again, again and again...
I woke up this morning to find a trashed disk on my backup terminal. I got it back after a boot sector repair and discovered....
During the night Windows 10 had tried to install itself without being asked And failed miserably all through the night as it tried and tried and tried again and again and again according to the events log and failed every time.
I NEVER asked it to do so, I haven't even selected the icon since it told me the update was ready a few days ago. Certainly not scheduled.
Really mad
I've restored a backup (it's the only Win 7 terminal I have) from a couple of weeks back and declined the Win 10 update reservation for now. I think Win 10 updates are a long way in the future here.
