What is SLMGR and How Do I Use It?

If you work in IT, chances are you’ve come across the term “SLMGR” before. But what exactly is it? SLMGR stands for Software License Manager, and it’s a tool that helps you manage software licensing on your Windows computer. In this blog post, we’ll take a closer look at what SLMGR is and how to use it.

So, what exactly is SLMGR? As we mentioned above, SLMGR is a tool that helps you manage software licensing on your Windows computer. With SLMGR, you can install, uninstall, activate, and deactivate software licenses. You can also use SLMGR to change the product key for your Windows installation.

Now that we know what SLMGR is, let’s take a look at how to use it. To use SLMGR, you need to open the Command Prompt as an administrator. To do this, press the Windows key + R on your keyboard to open the Run dialog box. Type “cmd” into the dialog box and press Enter. This will open the Command Prompt.

Once the Command Prompt is open, you can use the following syntax to manage your licenses with SLMGR:

slmgr /ipk [product key] - This installs a new product key on your computer.
slmgr /ato - This activates your license.
slmgr /upk - This will uninstall the existing license key.
slmgr /cpky  - This command removes license key details from the Windows registry.
slmgr /xpr - This checks the expiration date of your license.
slmgr /dli - This displays detailed license information.
slmgr /dlv - This displays detailed license information plus verbose logging.

VLMCS SRV DNS record for Microsoft KMS

In order to use KMS, your DNS must contain a _VLMCS._TCP SRV record that points to your KMS server. The _VLMCS._TCP. record is used by clients to find the KMS server when they attempt to activate their volume license edition of Windows or Microsoft Office.

Creating a _VLMCS._TCP SRV Record

If you’re using a volume license edition of Windows or Microsoft Office, you’ll need to create a _VLMCS._TCP SRV record in DNS in order to activate your software using KMS. The process for creating an SRV record may vary depending on which DNS server you’re using; we’ll be using Windows Server 2016 DNS for our example.

  1. Log in to your DNS server and open the DNS Manager console.
  2. In the left-hand pane, expand the server name, then expand Forward Lookup Zones.

  1. In the New records dialog box, select SRV record and enter _vlmcs in the name field and enter the FQDN of your KMS server in the Fully qualified domain name (FQDN) for target host field. Then click OK.

Now that you’ve created your _vlmcs._tcp SRV record, clients will be able to locate your KMS server when they attempt to activate their volume license editions of Windows or Microsoft Office products using Key Management Service.
Conclusion:

Having a correctly configured _vlmcs._tcp SRV record is crucial if you want to use Key Management Service (KMS) to activate volume license editions of Windows or Microsoft Office products within your organization. This blog post walked through how to create a _vlmcs._tcp SRV record on a Windows Server DNS server; however, the process will be similar on other types of DNS servers as well.
