Great price, but didn't activate. Error, 0xC004C003, going from Samsung installed WIN11 Home to WIN11 Pro. Tried phone activation per another review and didn't work. Found instructions per This Site to "Then, go to "Check for updates" and install Windows 11 Pro". No option to install WIN11 Pro, but option to update (KB5037853). Performed update and didn't work either. Found below link, performed step #3, and worked! https://www.thewindowsclub.com/windows-10-activation-error-0xc004c003

Haven't installed it yet but the acquisition process for two purchases have been difficult, possibly due to my own fault.

Installation was a breeze. I needed pro for remote desktop access, and once installed access was available.

As a volunteer with a national Not-for-profit Association, I purchased Windows 11 Pro for the added security to ensure if lost, files would be protected. Provides a greater sense of security.

Well, it’s Windows…the life blood for so many of us whose productivity depends on this operating system (yes, I know many will roll their eyes at this point). The price was outstanding so thank you TechSpot. I didn’t install the software right away and when I did I got an error saying my key was used on another machine, but using the phone activation option took care of the problem.

for some reason the lock settings for reminders and clander, ect. isent working now. super great price tho. got it nearly instantly. no issues upgrading from 11 home.

It was much less expensive than retail stores. Install was fine. The N100 NUC has not had a missed beat.

Installed perfectly - a snap to activate. The odd thing is that Microsoft keeps asking me to activate my previous Win 11 Home OS. Odd.

Excellent product upgrade for my new pc and had no problems applying the upgrade. Recommend this product to anyone and the product was at huge price point.

the only thing that sucks is that I did not see anywhere in description that the code had to be activated within 30-days... I only saw that AFTER I bought it, when I went to redeem/grab the code. So if you aren't planning on using it right away, then you should wait until you need it. You can't buy this and store it away for later use, which is what I was planning on doing.
