I understand that we should reset our old SP2 to factory default before exchanging for replacement (PC Settings -> Update and recovery -> Recovery -> Remove everything and reinstall Windows). My old SP2 has up-to-date hard drive backup imaging, but this time I've decided to just re-install my software on the replacement unit from scratch. Anything else I should do if I want the new unit to be a drop-in replacement (same name and everything)? Won't the Windows Store still list the old SP2 under its list of authorized machines? Should I deactive the old unit from Windows Store before wiping it? P.S. Subscription software like Office 365 and Adobe Creative Cloud should be easy enough to deactivate the old machine and install on new one (even after the fact). Must still take care to deactivate software with old-style product keys though (like ShadowProtect).
