Dual Boot Windows question.

Yes ,as far as I know there's only windows 10 home, windows 10 pro, and a couple letter variants that do & don't have certain languages and media related applications preinstalled. But yes it will be windows 10 pro

I don't know what puma was referencing, but every time I have used one of my windows seven pro or Windows 7 ultimate keys to register windows 10 it's always windows 10 pro even Windows 7 home becomes windows 10 pro, at least it always did for me

There's nothing to be lost because you can roll right back to Windows 7 if you don't like it it saves a shadow copy of Windows 7 if you use it to upgrade and if you do a clean install just make a back up it's not like your key is going to be wiped are used up

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

Nope it can't and vise versa u need the correct license for the Windows version u r running.

I have purchased a few Windows 10 Pro licenses on ebay works like a claim, my own is a "real" Windows 8.1 Pro Upgrade that I have upgraded to Windows 10 Pro
