Hi,

I upraded from Win7 to Win10 via the Windows update thing in Win7. I wanted to check if everything ran fine, but i wanted to get a clean isntall. When i was done upgrading i checked my Key via Magic Jelly Bean Keyfinder. I then formatted my C: drive and did a clean isntall via a USB stick. When I was done installing I tried to activate windows with the key i extracted and got the Error 0xC004C003. Is there any solution to this? Alternatively would my Windows 7 key still work?

Please help.

I didn't find the right solution from the Internet.
