I have been surviving quite happily without Windows for many years now 
but recently I have HAD to use it for only a couple of programs and I 
resent having to reboot for sometimes only 5mins a day - it would be 
excellent if I could get at the Win7 partition via a virtual arrangement 
but still have the dual boot option working OK if I need it . . the 
reactivation nonsense pisses me off . .

Thanks to all who posted! - it was much appreciated.
