Oh, somehow missed vlite reading the post. I'm sure that author well have a W7 version out soon, though it would be cool. We could make one and simply update it so it supports multiple versions of Windows along the way.
Vlite partially works with windows 7, there are other projects going on like Rt7lite and 7customizer at the msfn.org forums but are not as goog as nlite or vlite now,I am sure Guru can make a nice one.
