Would have given it a 4, but they were better the second time around. Loaded the program on the new desk top I built, but have used it yet. This was the second set of validation keys I ordered. The first set worked fine until i entered the validation key and got the message invalid key. Thought it was to good to be true. Latest set worked fine. They did offer to send another key, but the time ran out to get it. Overall a good experience, but not a great one.

I am giving my PC laptop to my grandkids and I wanted to migrate what was on the laptop to a Parallels Virtual Machine on my Macintosh Pro. This typically ends up the the need to re-activate Windows. It was really great to be able to purchase a Windows 10 Pro license (what was already on the original hardware) for a reasonable price. My Virtual Machine (a total clone of my laptop) is humming on my Mac. I can now erase the Laptop and give it to the grandkids. Thanks guys.

I am a very happy KeyMart customer! I upgraded from Win 10 Home to Win 10 Pro, so I can use my laptop with a digital projector. The download worked great, after I learned HOW to do it, (had to “activate” the download in Windows) and my programs are all OPERATING great — I had no need to reload any of them. And I backed up ALL my data to my exterior hard drive. And.. the upgrade came right from Microsoft! Go KeyMart!!
