Can I still upgrade to windows 8 when I have the anti-theft service installed from intel? Or will it lock down the computer?
According to What is Intel Anti-Theft Service? it does support Windows 8.
However according to here: Operating system and browsers
It only supports windows 7. Note: This article was updated more recently than the first.
This article, updated several months ago seems to indicate it will work:
It's probably the case that Intel haven't gotten around to updating all their articles but as they are contradictory your mileage may vary and you may want to get direct confirmation from them, or another user of their product.
I just spent quite a bit of time on the phone with intel at support. There is actually two different versions of the at service. 1.5 and 2.0. Only the 2.0 version works with windows 8. That's really nice because I just bought a 3 years of service that only works on windows 7. Don't get this service people. If you buy it ask spesifically for windows 8 support.
