When you upgrade with the free reserved copy from the GWX app on an activated Windows 7 or 8.1 PC, Windows 10 has a generic key included that will activate it.

If you clean or upgrade install...

Yes, but Windows 10 will not be activated going that route until you purchase Windows 10, and activate the installation with the included key.

Your best bet would be to reserve your free copy,...

Yes, but only after you do your free upgrade. Afterwards, you should be able to clean install 32-bit or 64-bit. :)

Correct to be able to activate the free upgrade when doing a clean install afterwards in the future. :)

Hey mate,

You will need to do the free upgrade first so that the activation will be locked on your PC. Afterwards, you'll be able to do a clean install on the PC anytime you like, and have it...
