This is NOT an upgrade! You have to install Windows Pro from scratch...

Curious, why did you find that? I believe it can be used for upgrading as well. But who wants to upgrade? Fresh install is cleaner in my opinion.

Sorry @FadyJ but my experience was different. I tried a number of routes including the straight upgrade in Settings from Home to Professional, and got a very unpleasant warning from Microsoft (automated, I assume) that the license was NOT valid.

Like others here have noted, the ONLY way it worked was to back out and do a full clean install (I also discovered that I needed to inject a small cfg file so that I could pick Pro during the initial boot).

In my case, this was on a totally new machine, so honestly I ended up doing 8 or 9 installs until I was satisfied that all was good. I'd be pretty unhappy if it were an older machine that I hadn't planned on wiping.

Turns out it was a Dell XPS (THANKS BEN) with an NVMe boot drive, so installs were like 10 minutes or less from plugging in the USB to first log in. God, so nice. I'm old enough to cringe and shudder at the days we had half a dozen 3.5" floppies that you had to shuffle in and out! IIRC those were 1-2 hour nightmares.

Matt I've purchased 4 of these keys in the last 45 days, every build I Install windows 10 installer which I download directly from Microsoft and install onto a flash drive. after the installation is complete I just go into the settings and add in my serial key it automatically updates and works fine.
