Sorry I'm late, I just ran across this. For future reference, this is how you fix this problem:
Enter Bios. Either DEL or F2 should do it.
Disable all DVD, CD, CDR, DVD-RW drives.
Reboot.
F8 for Boot Options, then choose "Safe Mode with Networking".
Control Panel then Add/Remove Software.
Upper-right Check "Display Updates".
Remove Hotfix #890859
Go to Windows Update website and tell it to hide that Hotfix so it never installs again.
Shut Down.
Turn back on then enter BIOS, enable your drives and boot normally.
That should do it... oh unless you want to go to Microsoft's HQ and throw a hammer through the biggest window you can find. They still don't take full responsibility for this conundrum.
