A Spanish website named Muywindows today released a couple of screenshots purported to be the first preview of Service Pack 1 for Windows 7. Muywindows got the screenshots from a Russian individual who wishes to remain anonymous. The screenshots were taken from a demo copy of a Pre SP1 Build of Windows 7 which will be made available to a selected group of testers.

The total number of updates released to date for Windows 7 is around 150, many of which are integrated into the various stages of service packs. The Service Pack is expected to hit the shelves in late 2010.
