Hello,
My brother recently installed Windows 10 on my PC,then changed it back,but now I get the message This copy of Windows is not genuine.
I am pretty familiar with this message,I tried activating my Laptop for 5 months with no succes.
I have a magical jelly bean keyfinder to enter it,but I always get the error above.

I tried solving this myself for 3 months,but everyone suggests some automated phone system support which I can't see in the Windows Activation panel,only 3:buy a new product,change the product key and contact microsoft

I have Windows 7 Home Premium with Microsoft Office 2010
