Had 360IS on a couple of XP PCs for over a year. Followed the 360TS beta saga here as it seemed to be being morphed into something useable 22.214.171.1245 released at Christmas - took the plunge on an old Vista laptop. To say that it is really impressive would be an understatement. Wow! And 'icing on the cake' is the built-in Windows patching feature! 'Windows Update' stopped working on his PC about 2 years ago after some system files got corrupted. (see first 2 images) Tried re-installing Windows Update service - didn't fix it. Tried recovering from back-up - didn't fix it. Tried "in-place install" from a Vista CD - didn't fix it. Microsoft recommended a reset to factory settings... that would be 2006 factory settings wouldn't it dear MS tech support guy, wouldn't it? - didn't even bother. But 360TS has got me up to date without 'Windows Update'. Woohoo!
