Leo says that he'd have to make a real effort to get Windows 7 these days, so that's tough. The problem for Bruce is that there's not drivers for Windows 8 for the printers he's using. Could Bruce use the old hard drive and just plug it in and run Windows Vista on the new PC? Leo says not really. Some things won't work and Microsoft will get a report that he's not using the same computer and he'll have to re-register.
The easy fix here is to just buy a copy of Windows 7. He can get it at NewEgg. Leo believes that Microsoft will continue selling Windows 7 because businesses will demand it.
