Windows Server 2022 Product Key

JayTechTips Sue et al.
Please mind that possession of an activation key and even a sucessful activation does not mean you have been given/ obtained a legal license.

A license is not the key. It is a legal permission to install and execute software as per Microsoft Product terms and these differ from channel to channel like Volume Licensing, CSP (MCA) or OEM.

While Windows Server licenses, even OEM in EU, might be sold, it is the requirement of the seller that this license is rightfully in his hands and he may resell these as per OEM terms or product terms. This could be the case if the seller has bought more licenses than used or hardware being assigned with these licenses has been revoked or decomissioned. 

Licensing is a complex material and not very accessible due to legal language.

KMS keys mentioned here are generic keys activated against a KMS Server OR Active Directory Based activation (ADBA), which is my preferred method as soon the Windows Server is domain-joined.
These generic keys are publicly available. KMS Host keys, so these used for activation with ADBA or KMS Server may not be shared or resold as they are part of contract of the licensee and Microsoft.

Licenses generally are available through authorized resellers or partners (directly or indirectly).

congyennhat please find the Windows Server 2019 in my.visualstudio.com if you have a subscription or in Microsoft Windows Server evaluation webpage.


Here you'll find some additional guidance about Windows Server installations and upgrades.

Affandrg0786 you can find some guidance and warnings here about your question on Windows 11.
Please read through the benefits and limitations before your decision, as you might regret this.

I invite you sharing your PC config over there so I can check if it is misconfigured (happens very often) or truly not intended for Windows 11. This forum is for Windows Server Insider, not Windows 11.

You can get the latest Windows server 2022 evaluation edition from
https://www.microsoft.com/en-us/evalcenter/download-windows-server-2022
However, this is evaluation edition for 180 days, if you only want to use it for some test, i think it is enough, but if you need the full standard or datacenter edition , you need to convert it by using this command as administrator :
Dism /online /Set-Edition:ServerStandard /AcceptEula /ProductKey:XXXXX-XXXXX-XXXXX- XXXXX-XXXXX
Dism /online /Set-Edition:ServerDatacenter /AcceptEula /ProductKey:XXXXX-XXXXX-XXXXX- XXXXX-XXXXX
The product keys provided by chinchin85 are generic key , it can only help you to convert it ,but it cant help you to activate it
Because we have the same situation, i was trying to find a free key, but they were all not working , I think I will try the recommendation from Sue1998, instead of buying it directly from Microsoft !
