I'm running this on a Vista RC2 machine but not my xp machines. Sure it eliminates the needs for third party apps, but Im not 100% sure I like that!
Please note - the beta is FREE but once Live OneCare goes 'live' - most likely with the release of Vista in early 2007,it will involve some type of paid subsription for it's full features
