Worked great, my license activated after I installed the ISO from Microsoft's site. For whatever reason it took me a few times inputting it for it to activate it, but I got it done in ~5 minutes, so no big deal. Fully licensed and good to go now, excellent deal given that it's over $6100 cheaper than a retail key lmao. Highly recommended!

Its windows, what is there to say? Easy to activate and use as expected. Windows 11 Pro is the only one worth using though.

This particular Windows 10 software was an absolute game changer for my first new desktop PC since high school (I'm in my 30s now). The build was also my first COVID project which endears it even more to me. In my choice of OS, Windows was the only way to go for me personally and professionally and the price is really the discriminator here. The price point on the software justified my entire PC build and kept me in budget. I would probably be sporting a lame laptop from Amazon Warehouse if it weren't for this excellent, and surprisingly-simple-to-activate copy of Windows.

Just purchased a Windows 11 Pro OEM key through Transaction was smooth, and the key was received immediately after I claimed it. I used the key after I upgraded a Non-Activated version of Windows 10 Pro to Windows 11 Pro. The key was accepted and Windows 11 Pro was activated immediately without any hassles, phone calls, etc. A very smooth and successful transaction. Thanks to Kinguin and!
