Had a series of power off failures and failure to boot on one of my Win 7
PCs - and in an elimination exercise exchanged hard drives with another less
important one. Both legitimate licenced copies. Fault actually seems to have
been a power supply on the original machine (but fault has 'gone away') So I
left the drives swapped 'just in case' and altered their network names to
suit. Now several days later the first to be swapped is coming up claiming
it has a non genuine windows copy (as the mother board details don't match)
No doubt the other one will do the same thing tomorrow as they were
re-instated a day apart.

So now my tomorrows schedule is put awry as presumably I'll need to
re-configure the machines as they were to get them working again before I
can do the work I intended.

Thanks a bunch Microsoft - love you to bits !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
