A few weeks back you may recall I had issues when I exchanged hard disks between two pretty well identical legally licenced Win7 machines as a diagnostic aid. (Compaq / HP SFF DC7600's) They then reported illegal operating systems. That was sorted by reverting them to whence they came. However I have a third Win 7 machine that recently flashed up a message that the copy of Win7 wasn't legal and to follow a link. That took me to a Microsoft page that emblazoned across the top told me that as my software WAS legitimate, I was entitled to buy certain upgrades !!!!!!!
Now all these three machines are running Win7 loaded from the same disk and having the same licence number that has been verified by Microsoft as being legal. With Win7 professional you can use it on three machines.
I can sort of understand that if my licence number had been thought odd when I swapped the hdds in the first two, then just maybe the third machine flagged up as it had the same number. But the cynic in my says that actually this is just crude advertising to sell more product. Anyone else had this? All three machines are now running fine and do regular 'update' checks.
