Hello all, I've recently upgraded my PC and now trying to activate Window but having some issues. Then I tried to input my product key Seen below but it kept telling me there was an error message and that this version of Windows could not be activated with a preveious lience.
I thought using my old product key would work, but I kept getting error messages saying it wasn’t valid anymore. After trying a few different methods, I ended up using a ms office activator to activate Windows, and it worked like a charm. I later found out that upgrading certain hardware can cause your license to be invalidated, especially if the key was linked to the previous setup.
