Windows 8.1 RTM - Works with Windows 8 key?

[stoofa]

Asking this on behalf of a colleague here - I don't know the answer myself, so can only assume someone here does
This chap has Windows 8 Professional - all legit etc.
Needs to do a system rebuild over the weekend so thought he might as well install Windows 8.1 RTM
So he's gone and grabbed the ISO for 64bit Windows 8.1 (don't know where from - that is his business etc.) and he's turned that into a bootable USB installer.

So he'll be installing this on an empty HD. Does Windows 8.1 prompt for a product key during installation and if so, can he simply enter his existing Windows 8 key at this point?
Of does he chose to skip entering a key during install (if you can?) and then enter his key afterwards?
Of is he looking for an 8.1 RTM key which he can use temporarily for the installation and can then change the key over to his own one?

Cheers forum.

In answer to your question - no, I wouldn't want to.
Hence the reason I'm waiting for the actual proper release
My colleague however.......
I've told him how he can check the hashes on the downloaded file - if he does it or not I don't know. Just hope he also found an OEM key to go with that then

Just had an email from the chap I work with. He tells me the process was all rather straight forward.
Installed 64bit Win 8.1 Pro using the leaked OEM key.
After install went to product activation, immediately said this key was invalid. Chose option to enter different key, entered his own Win 8 Pro and it then proceeded to activate online - no need to phone it through.
So he's all activated.

Me....I'll stick with 8.0 until official release I think.
