Everything worked completely fine before. Something went wrong with my desktop computer and I couldn't turn it on anymore so I gave it to a company to fix it, which they did. After I got it back I've had this "Activate windows" watermark on the bottom of my screen. It says "go to settings to activate windows". If I go and try to do that I get this:
"We can't activate windows on this device as the previous windows was not activated prior to upgrading windows 10. Go to the store and buy genuine windows. Error code: 0x803F7001"
I got my desktop computer in 2015 and bought and installed windows 8, then later upgraded to windows 10 (it was a free upgrade at the time). I don't know what's happened but I'd like to be able to activate windows so I can personalise some things.
