I remember years ago my son bought a laptop from Best Buy; it was a Windows 7 Computer that was upgraded to Windows 8. About 6 months afterward, he got a message saying his copy of Windows was illegitimate and he needed to purchase a retail version. When I took the laptop back to Best Buy they first tried to say they were not responsible. After working my way up the latter I finally found a manger who agreed to install a new retail version for free. It turned out when upgrading their computers they violated their MS licensing by installing OEM versions of Windows 8 they had for new computers that were not supposed to be used to upgrade PCs.
BB/GeekSquad == shady.
Similar with my son's laptop.
Original Win Vista. HDD died within a couple of months.
Took it to BB for a warranty replacement.
"Sir, did you create the OS backup DVD?"
(me) 'No.'
"well, we're going to have to charge you $250 for a new OS and the installation."
(this, on a $300 laptop)
'WTF??? No dude, just replace the drive, I'll do the OS reinstall myself.'
He really really did not want to go down that road.
'Dude...replacement drive, now!'
Drive replaced, a little larger than original.
I still have this cheesy laptop. It was my Day 1 test box for Win 10 Tech Preview.
