Can a Windows 8 Pro OEM Key activate Windows 7 Ultimate?

[EpicCrumbCake]

Has anyone experience with this?

I'm trying to activate a (already installed) copy of Win7 in order to upgrade to Windows 10.

Depending on what works I'll buy a 8 or 10 key. I'm pretty sure that a 10 Key won't work to activate 7

 

Or is there another way to Upgrade to Win10 without having to reinstall Windows?

No, only a Windows 7 key will activate Windows 7.

However a Windows 7 key will activate Windows 10 still.

As far as i can tell you installing windows 10 from fresh is a way better experience than upgrading ,(especially if you are using a ssd)

Is there a particular reason you don't want to just re-install?

But no, Win 10/8 keys cannot be used to activate Win 7.

 

I'd recommend a clean install.

Yeah, that's what I feared. I won't get a Ultimate Key for cheap, barely found a Home Premium Key.

True, but that means more work for tech support (me).

Relatives that can barely use computers are the best

 

Thanks guys

Just an FYI, you don't need to activate Windows 7 to upgrade to 10 before hand

I tried it earlier today. The Update Assistant requires a valid Windows 7 License in order to continue. I think it *was* the case while the official Windows 7 to 10 Update period.
