Download Windows Vista SP2 Pre-Beta Via Windows Update
Here’s something all Vista fans are going to like. The next security update, Service Pack 2, that is still in pre-beta can now be downloaded from Windows Update with just a small registry hack.
A couple of weeks ago, few Microsoft beta testers were given Windows VIsta SP2 to download and try. You can now also download Vista SP2 directly from Windows update using the trick given below. This registry trick makes a small change in your registry so that Windows Update thinks you are one of the beta testers.
