Wow, loads of excellent posts on this since I last checked hehe,
I respect and understand exactly where all you 'pay for it' guys are coming from, and the same to the 'get away with it if you can' guys, but i have to say solely because of my monetary situation I am still the latter.
I have one question for you, i need to know, with regards to my installing this OEM version of Vista on a second PC whilst the first one is still running, if they both run at the same time and connect to the net and update etc does anything happen? or do both PCs with the same OEM OS run just fine, without a hint as to them running off the same product key?
And also, if i do cheat and install this OEM Vista on my second PC, will I be able to use the windows 7 upgrade version? Do upgrades install ok on OEM versions, and could it 'know' that the OEM has been used on 2 different PCs?
Putting the whole legality and copyright stuff aside, do you know if it will technically work or not?
My friend works in a PC factory of some sort so he is looking into getting me 64bit 7 Pro full retail version for a bit of discount, if he can i will go for that, im sure that will please you 'pay for it guys'

understandably.
Cheers
