[SOLVED] Will win 10 pro activate with a win 7 pro key code?

[LTVETTE2]

I have an old dvd with win 7 pro on it that I never used. I do have a new build on horizon, and am holding off on a copy of win 10 pro to see if I can actually use the win 7 pro code. Will it work, or should I hedge my bet and get a copy of win 10 pro in case? I don't want to end up with an unused dvd of win 10 pro kicking around, and no place to call home.
Thank you, LT

Try it.
If it doesn't work, you can run windows 10 unactivated, until you get a valid license key.

Yes, it should work.
I did exactly this a few weeks ago.

At worst, your new Win 10 install is Unactivated, until such time as you purchase a valid Win 10 license.
It will run just fine.
