An unauthorized change was made to Windows

I was trying to uninstall Microsoft Office 2010, I ran the Microsoft Fix It program because I was having trouble uninstalling it from the Control Panel, it restarted the computer and when it came back on I got the "An unauthorized change was made to Windows. Windows has discovered a change that will result in limited Windows functionality. Use the link below to find out how to fix Windows" message.

The "Learn more online" option led me to a genuine validation site which was trying to validate for over an hour with no results.
The "Close" option just sends me in a loop back to the "An unauthorized change was made to Windows" message. There is nothing but a black screen behind it.

I now have it in Safe Mode and am backing up everything in case of the worst case scenario. Please help, thank you!

Once everything is backed up, do a System Restore to before this happened. That should fix the problem.
