So I was using windows 10 pro unactivated for a while after I built my pc but today I decided to buy a product key. I bought a windows 10 home key (legit key from microsoft) and I tried activating and I got an error saying the product key didn't work (0xc004f050). I tried restarting my pc and now the watermark is gone but I still can't access any of the personalisation features. Does it take some time to fully activate?
