Windows 10: I cant find my original windows key but i bought a new one but cant activate it

I downloaded a virus downloading mods and my windows key is gone so i just bought a new key but cant activate it.

:)

 

Windows 8.1 pro + WMC key activation

yeah, just don't forget that MCE gives you a new Windows key.... I had activation errors untill I entered the MCE key....

 

[FF]   Origin game keys

It doesn't work on the humble bundle keys, I tried it. however ea games bought on steam can be activated on Origin

 

Upgraded from Windows 7 to Windows 10, then bought new computer and trying to activate here instead.

You could honestly make this easy on yourself by using the Windows 7 Professional key to reactivate on the new machine by chat support.

• Activate Your Windows 10 License via Microsoft Chat Support

The thing you are trying to do is use the activation troubleshooter to reactivate the license on the new machine.

But that is more helpful if you are using the old machine, not the newly built machine.

Also, lets keep in mind, we don't know the origin of the Windows 7 license.

It depends on how Windows 10 was originally configured on your computer.

If its a full retail store bought license online or offline, it is transferable to a new computer or motherboard.

If its the free upgrade from a retail store bought Windows 7 or Windows 8 license, it is transferable to a new computer or motherboard.

If its the free upgrade from a OEM preinstalled Windows 7 or Windows 8 license, it is NOT transferable to a new computer or motherboard.
