Volume License Keys: toll-free call for Malaysia

I would like to activate our Windows Server 2025 Standard, but the product key can no longer be obtained using the previous method. We are now required to call the toll-free number for activation.

I tried calling the number provided on the website, +60 1 800 80 1432, but it appears that the number is not in service.

Could you please provide us with the correct contact number for Windows Server activation in Malaysia, or advise if there is any other solution to activate the server?

For Windows Server 2022 and earlier versions, we are able to obtain the product key through our account, but we are unable to do so for Windows Server 2025.

Thank you.

    Hi @Nethanel Jushua

    Two different things are getting mixed together here, and that's why the phone route isn't working for you.

    The number you called is the activation call center. It can only activate a key you already have, using an installation ID, which is why it loops. Your actual problem is earlier in the chain: the Windows Server 2025 MAK key hasn't been added to your agreement, so there's nothing to show in the portal. That's a licensing operations task, not an activation one. It's a known gap for 2025 keys under existing agreements with Software Assurance.

    Here's how to get the key:

    • Check the Microsoft 365 admin center first: Billing > Your products > Volume licensing > Product keys, filtered to Windows Server 2025. If it's there, you're done.
    • If it isn't, open a support request from the same admin center and ask Volume Licensing Support to add the Windows Server 2025 Standard MAK key to your agreement. Mention your active SA and that the key is missing. That's exactly what resolved it for others.
    • Your reseller or LSP can also raise a licensing case for you, which is often the fastest route in Malaysia.
    • Once the key is in the portal, activate with slmgr /ipk followed by slmgr /ato. If you already run a KMS host, the built-in GVLK activates against it without needing the MAK at all.
