Reboot and press F8 right after the Bios Screen.
Select Windows Recovery Environment [this should be the top option].
Select keyboard option and login for your account.
=> Open the "Command Prompt"
=> find your Windows directory (my PC was on D:)
=> cd to Windows\WinSxS folder
=> type in this command move pending.xml pending.old
=> exit command prompt
=> run "System Restore"
=> select the option for Service Pack 1
=> exit and reboot
That fixed my system...
