upgrade to 10, revert to 7, then back to 10
I have upgraded all of my one-generation-back Win boxes, but want to ease into 10 at leisure.
As I understand it, the registry is modified at the first upgrade to 10 with the activation "approval", but I am concerned that this will be lost upon reversion to the earlier version.
So if I revert to the previous version, say 7 or 8.1, can I then "re-install" 10 after July 30 without having to buy a license?
