So the motherboard on my old PC died and rebuilt the PC. Used old hard drive with old Windows installation and it eventually came up saying I need to reactivate. At one point in the past I did tie my Windows install to my Microsoft account. Problem is, I logged into the same account on my laptop and it apparently tied my laptop Windows key to my account now. I reactivated Windows on my PC but had to reactivate with my the key tied to my laptop since that's all that came up. Do you have to create an individual Microsoft account for each individual machine that you have?! Is my laptop going to cry that it's not activated next time I start using it because I've used that activation key on my PC? Sheesh what a nightmare.
