As I mentioned earlier this morning, Microsoft has pulled the botched patch KB 3004394. That's the Windows Root Cert patch causing endless problems -- Windows Defender wouldn't start, installing KB 3004394 blocked installing other Windows Updates, UAC prompts appeared in the weirdest places, MSE wouldn't install, VirtualBox stopped working, and on and on.

KB 3024777, specifically designed to take out this week's Black Tuesday fiasco, KB 3004394, on Windows 7 SP1 and Windows Server 2008 R2 SP1 machines.

If you had a "Windows not genuine error", this is probably why:

Step 1. Download and install KB 3024777.

Step 2. Reboot. Then, just for the heck of it, reboot again.

Step 3. Click Start, right-click Computer, choose Properties, and look at the bottom to see if you've been activated. If you haven't, click the link to Activate Windows Now. Reboot again.
