So now Windows 10 is linked to my hardware and no license key is required. So I can install windows 10 as many times as I want on the one machine in a dual boot environment?
Technically yes
Not really.. it would be a violation of the EUA to run both 7 and 10 at the same time. You would have to have a unique key for 10 to run both in a dual boot configuration.
EAU = End users agreement..
I see no mention of 7
He has both 7 and 10 listed in the OS's he uses.
Yes, I am talking about multiple copies of windows 10 on a single machine. The activation servers don't check for an already installed windows 10 copy?
If you have separate legitimate keys there would be no issue.
There are no keys for windows 10
So what, the question has nothing to do with 7 or the legalities, it has to do with if he can with 10, I suggest you read the question, although why anyone would want more than one copy of 10 is beyond me. I doubt MS will be sending out a helicopter and a sniper because he has more than one copy as a duel boot.
Regards Sir
That would mean your using the key from an upgrade.
When you install/upgrade to 10 you need a valid key from either 8 or 7.1 to be there on the PC. Or to do a clean instillation you need a key to accomplish this.
