What worked for me:
Could not get into safe mode or any other mode so:
1) Boot off Windows 7 64 bit recovery disk
2) cd to windows root, in this case D:\
3) mkdir x:\temp
4) then enter this code:
Code:
dism /image:d:\ /remove-package /packagename:package_for_KB3097877~31bf3856ad364e35~amd64~~6.1.1.1 /scratchdir:X:\temp
where the "image" is the windows installed drive letter, in this case D: when booting from the recovery disk
5) after a minute or two it said it was complete then I rebooted.
6) After windows came up it immediately started some windows update, then got different login profiles to
use as expected. Picked the main one, logged in and everything looked normal.
7) about 3 minutes later windows said updates were done and it wanted to reboot so I did.
8) Windows booted up normal and everything looks fine.
Such a quick fix, I hope I get more of these.
