I have a desktop with Swappable Hard Drive Bays. The question is, I have 2 hard drives that both have windows 8.1. One drive has a capacity of 1TB and the other is only 500gb, the 1 tb is a clone of the other, done thru acronis. I use both, one as back up in case the other fails. Can I upgrade both of them to windows 10? If so, would swapping them occasionally affect activation? Would it affect the HWID if I swap them once in a while to transfer files and for maintenance and updates? Thank you.
