I have t420 with windows 7 and I bought second mSATA SSD to clean install windows 10 on it and activate it with the OEM Win 7 pro key, but I want to keep the old win 7 on old HDD and use It alongside with Win 10. My question is, will I loose Windows license if I use both win 7 and 10 simultaneously on one PC?
I searched the answer everywhere and some people say that I will lose Windows license and some say I do not. What is your opinion?
I recently rolled back to Win 7 Pro after buying a Win 10 upgrade. After almost two years I decided I didn't like it and went back to Win 7 Pro.
After buying a Dell G3 with Win 10 Home, I upgraded using the key from my T520 and was activated immediately to Win 10 Pro on the Dell G3.

How would you do a clean win 10 install after upgrading the current win 7 build to win 10? Would you run the setup in a set of win 10 ISOs? That would in all likelihood nullify the win 7 to win 10 upgrade.
Is there even a active microsoft link to upgrade win 7 to win 10 in place, without using a set if w10 install discs?
On this I'm giving this a lot of thought myself. Yes it is a possibility, BUT, if you don't try to keep both HDDs / SSDs in the system at the same time, probably not.
To do this you will have to back up your current win 7 and restore it to the 2nd HDD / SSD. I would then use That 2nd drive to "upgrade" to win 10 with the original drive not in the system. his way your original drive is never messed with.

The activation contains some minimal hardware-specifics of that registered PC/laptop.
After registration you can go back to any other OS on that machine and let's say a year later go back to (re)install W10, and off you go without any further ado...
