    Hi:

    I'm new to this sort of thing, and not as technical as many of you are. How can I make this program support checking of Windows Windows Server 2025 keys?

    Also, I tried a Windows Server 2019 key using the Automatic Detection, and it seemed to output correct data. However, I'm not sure about the outputs I got for a Server 2022 Standard key. It described the product as Server 2021 RTM Retail. Does "retail" mean boxed edition retail, or can it mean OEM packs as well? Why did it describe it as "Server 2021 RTM"?

    What is the Custom.. option for?

    Server 2025 keys are already supported

    Server 2021 is the official name for Server 2022 in pkeyconfig files

    Retail is not OEM
    you can easily google or ask ai about "windows retail vs volume vs oem" to know the differences

    I don't see an option for it. You have a dropdown option for it? If not, how do I get it to check a Server 2025 key?

    Yes, I'm well familiar with the differences between retail and OEM. What I'm saying is that when I entered an OEM key, it output data describing OEM. Or maybe it was the other way around. Darn...I'll try it again.

    Ah, I see now. Thank you.

    Is it correct that the program is just checking the format/sequence of numbers, not actually contacting servers across the Internet to check if a key has been used?

    The online check can only be performed for MAKs to see the remaining number of activations. That's what checking the "MAK count" box does.

    For other types of keys, no such feature exists from MS' site.

    Thanks. Is there any way to know how many MAKs in total you get before ever installing an OS/program? Is it a commonly-known thing or an MS secret?

    It's not a fixed number. It depends on which contract those keys were purchased under, and they can be upgraded or recharged later as well. If you bought a new key, you can check the total number of activations. You can even activate it beyond the activation limit using CID, up to a certain number of additional activations, until Microsoft blocks the key.

    Regarding online validation for other key types such as OEM and Retail, to check whether they can activate, you can use PKeyMaster.
