Greg from Aspen Park, CO

Episode 1383 (27:46)

Microsoft Windows 10

Greg has an employee who downloaded the 32 bit version of Windows 10 and installed it by mistake, rather than the 64 bit version. Can he reinstall it? Leo says that he'll probably have to wipe the drive and install from scratch. So he should make sure to backup the data first and then format the drive. He can't just upgrade on top of it, unfortunately.
