Have you tried to reactivate it?

 

[manv]

Open command prompt as admin and enter the following : SLMGR -REARM if that doesn't work try replacing the - with /. Your windows activation will be taken away but no worries. Input the windows 7 key you own and reactivate thats all. But if you do have a pirated version of windows I cant help you.

How long where you running 10 before you went back to 7?

It automatically activated soon after. Thanks anyway
