Vlite Vista SP1 Integration

According to Vlite and Winbeta Microsoft has confirmed that there will be no way to directly slipstream SP1 into Vista.

Of course, that doesn't mean it can't be done and the guys over at WinBeta have been working hard on the problem. They've released a Vista SP1 Reverse Integration Guide which will walk users through an involved process of reverse integration.

After looking over the guide I'll say this is for more advanced users and is probably not for the average user. This of course is not official nor an easy method. However it does look possible, and I'm sure they'll be researching a way to come up with a less complicated method.
