Microsoft is enforcing an update that will update your WGA (Windows Genuine Advantage) tool. It will scan different points in your registry to see if your copy is legit or not. If it's not, you will be notified and within a week, you will not be able to boot into Windows.
Here's the MSKBA. You may have noticed that a lot of MS links on their downloads page have a new icon beside them that symbolize WGA.
