First of all, if you download the WIndows Server 2022 Standard evaluation to make sure all driver(s) is installed and testing make sure is fully working before you make activation into retail Edition..
Use this CMD command "Run as Administrator: then at the Command prompt: Dism /online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula
Then wait while doing Dism downloading to converted from Standard evaluation to Standard Edition Retail. then reboot the server and it activated..

I am running Xeon 12 cores 2.40GHz with turbo 3.50GHz, 32GB ram DDR4 X99 Intel Motherboard with Hardware RAID controller 6 SSD, 4 HDD (aprox 10TB total)..

Important is first install Windows Server 2022 (without key at this moment) then install Drivers first and see everything working proper, then place your License Key, then activate.. I will keep up to date..

Works very well! Follow the guide given by then to activate. Works a treat

i used Powershell then:

Dism /online /Set-Edition:ServerStandard /AcceptEula /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

replace xxxxx with your code purchased.

I was extremely worried that this would be some sort of scam but this legit worked to activate my windows server 2022 standard so that I can operate my Minecraft server and 7 days to die server while being legit.
