How to Activate Windows Server 2008 R2 Standard Edition with a KMS Client Product Key
If you are running a volume licensing edition of Windows Server 2008 R2 and you want to activate it with a Key Management Service (KMS) host, you need to install a specific product key on your server. This key is also known as a Generic Volume License Key (GVLK) or a KMS client key. By default, Windows Server 2008 R2 has a GVLK installed, but you may need to change it if you have converted your server from a retail edition, a Multiple Activation Key (MAK), or a previous KMS host.
In this article, we will show you how to find and install the correct KMS client product key for Windows Server 2008 R2 Standard edition, and how to verify that your server is activated successfully.
Step 1: Find the KMS Client Product Key for Windows Server 2008 R2 Standard Edition
The first step is to find the KMS client product key that matches your Windows Server 2008 R2 edition. You can use the following table to look up the key for your edition:
| Operating System Edition | KMS Client Product Key |
|---|
| Windows Web Server 2008 R2 | 6TPJF-RBVHG-WBW2R-86QPH-6RTM4 |
| Windows Server 2008 R2 Standard | 4GGC4-9947F-FWFP3-78P6F-J9HDR |
| Windows Server 2008 R2 Enterprise | 7PJBC-63K3J-62TTK-XF46D-W3WMD |
| Windows Server 2008 R2 Datacenter | QX7TD-2CMJR-D7WWY-KVCYC-6D2YT |
Step 2: Install the KMS Client Product Key on Your Server
The next step is to install the KMS client product key on your server. You can do this by using the slmgr.vbs script, which is a command-line tool for managing product activation and licenses. To install the product key, follow these steps:
- Open an elevated command prompt on your server. To do this, click Start, type cmd, right-click Command Prompt, and then click Run as administrator.
- Type the following command and then press Enter:
slmgr /ipk slmgr /ipk 4GGC4-9947F-FWFP3-78P6F-J9HDR- You should see a message that says "Installed product key successfully". This means that the product key has been installed on your server.
Step 3: Activate Your Server with a KMS Host
The final step is to activate your server with a KMS host. A KMS host is another server that has a special product key installed that allows it to activate other computers on the network. You need to have a KMS host available on your local network before you can activate your server. If you don't have a KMS host, you can learn how to create one here.
