Windows 10: would my windows stay activated in this setup or do i need to buy new?

I stand corrected and I'm glad of it because that what I am doing. I am dual booting with my original Win 7 on one SSD and my upgraded Win 10 on the other. I gave a conservative answer in fear of possibly encouraging the OP to violate the EULA. Looks like we both win.

 

I agree with you but this is one for lawyers to debate. It is a principle of law contracts have to be fair, and I think MS would be hard pushed to say it is reasonable to keep installing and uninstalling to meet EULA. I SERIOUSLY doubt MS would ever take a single person to court for this. At most, they might revoke the Windows 7 key, but they would have to alter EULA to make it clear. Of course, they could blanket stop such keys, but then how could you have reverted?

Frankly, I think it is nitpicking when we say it is not permitted, as we all know it works.

I accept (correctly) forum does not condone piracy but reality is there are far more serious EULA transgressions eg you can transfer dgital licences to new device even if original was OEM, or user bought a vlk or own system builder key etc.

So long as we do not encourage use of illegal tools eg password crackers and make it clear when EULA is being violated, I believe as a forum we have met our obligations.

 

you guys have been really helpful! just finished installing W7 on my second drive and its activated it seems!

 

I think Microsoft's reasonable argument would be that if you want to run two different editions of Windows then buy a license for each one. That seems like a pretty reasonable argument.
