I recently purchased a dell xps 13 which came with windows 8.1 which I immediately upgraded to windows 10. After the upgrade the windows key verification box kept coming up as though my win 10 wasn't activated. So I entered the key for I guess win 8.1 that came on the laptop originally and I immediately get the error message *unable to verify, contact support helpline* So I thought maybe Microsoft is making you pay extra or maybe my key is wrong, so I went to the systems page in control panel and did the change product key and entered the same key which worked, and the systems page says my copy of windows 10 is activated. So why am I still getting this windows key verification page every 5 mins that wont let me verify my key even though its already activated.
