I am not asking if I can activate more products. I am asking what happens to softwares/windows which are already activated before it was banned/expired.
I just told you that as well. The software won't necessarily go bad that is already activated but it MAY. You need to be more specific on how the account was banned. If it was banned for false info then the keys can be banned as well meaning all products will flag as non-genuine now. It really comes down to how extensive Microsoft goes when they ban the account (essentially how generous that employee feels). No one can tell you the specific rules besides a Microsoft employee but I a letting you know from my experiences. I have keys that were activated a year ago where the account was banned 6+ months ago and it still works but I also had people complain after a month when the account was banned and it was invalid.
If people could offer you a lifetime guarantee that it would NEVER go bad even if it was banned the keys would not be going for less than $10 each.
Typically expired accounts just won't let you activate it anymore but should not go bad on already activated PCs
