I had a problem using the licence I'd bought, so emailed Support for help and got a helpful reply back in a matter of minutes! I must have copied something down wrong because nothing was working but Daniele from the support team stuck with it and sent me a further 4 rapid-response emails that got me set up and activated. I really can't fault the support on this purchase, it was truly first-class.
I'd have no hesitation in buying again from Gamers Outlet.

This worked perfectly despite my initial scepticism! Be sure to activate using the code you get when you click "download" in your order summary, once you have followed the initial steps using the generic code.
I had to email support to work this out, and they were exceptionally helpful and extremely quick to respond!

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
