December 12th updates killed my win 8 install
I had a windows automatic update session on December 12th 2012.
After the install the start screen was completely unresponsive.
I tried to boot into safe mode I could not.
I could only access the task manager screen, and could only log off switch users or
shutdown or restart.
I booted using a win 8 Pro install disc I tried several of the advanced repairs none would work so I opted for a refresh, this did little or nothing, other than blowing out all of my office files...
I was able to log in using my domain admin credentials, reset the machine admin password (which no longer worked) once logged on I has access to a new profile tried to do a system restore, it was greyed out (as it had been when I tried from the win8 boot
I looked for my documents which seemed to be all there I copied them to a flash drive so most of what was lost I could retrieve ( my outlook.pst file was no where to be found..
I was able to get a small amount of functionality back to the start screen with my original profile enough to get to the desktop and check for updates there were still 19 there and at least 4 more cumulative after that.
That did little to fix the problem.
I've moved back into my win7 box, and I'm ready to give up on the win8 pro install.
With backups and the like I've only lost 11 days worth of e-mails, any changes made to my contacts, so all in all not a disaster.
This was a huge disappointment.
I am a domain admin and was evaluation win 8 for a possible replacement for win 7.
My suggestion for what it's worth, wait for SP1, and I am loosing faith in the automatic update process.
