Command Line to List Licenses on KMS server

October 8, 2019 amida168 Windows 0

One colleague was wondering about the licenses on our KMS server. I helped him look for a list of licenses on the KMS server. Later, I found that the same script slmgr.vbs which we used before to activate the license can be used to list the licenses on KMS server.

If you’re thinking about purchasing a new GPU, we’d greatly appreciate it if you used our Amazon Associate links. The price you pay will be exactly the same, but Amazon provides us with a small commission for each purchase. It’s a simple way to support our site and helps us keep creating useful content for you. Recommended GPUs: RTX 5090, RTX 5080, and RTX 5070. #ad

To do it, open a command prompt or a PowerShell prompt. Type the following command:

cscript c:\Windows\System32\slmgr.vbs /dli all

Here is an excerpt of the sample output:

Name: Windows(R), Professional edition
Description: Windows(R) Operating System, OEM_DM channel
This license is not in use.
License Status: Unlicensed


Name: Windows(R), Enterprise edition
Description: Windows(R) Operating System, VOLUME_KMS_W10 channel
This license is not in use.
License Status: Unlicensed


Name: Windows(R), ServerRdsh edition
Description: Windows(R) Operating System, OEM_SLP channel
This license is not in use.
License Status: Unlicensed


Name: Windows(R), Education edition
Description: Windows(R) Operating System, OEM_DM channel
This license is not in use.
License Status: Unlicensed

Note that if you type the command in a client OS like Windows 10, it lists licenses for client. If you need a list of licenses for server OS, you will need to type the command on a server.

Here is a sample output on a server:

Name: Windows(R), ServerStandard edition
Description: Windows(R) Operating System, VOLUME_KMS_2012-R2_WIN10 channel
This license is not in use.
License Status: Unlicensed


Name: Windows(R), ServerStandard edition
Description: Windows(R) Operating System, VOLUME_KMS_WS19 channel
This license is not in use.
License Status: Unlicensed


Name: Windows(R), ServerStandard edition
Description: Windows(R) Operating System, RETAIL channel
This license is not in use.
License Status: Unlicensed

/dli option lists the basic information for the licenses. Use /dlv option if you want detailed information. For other options, type

cscript c:\Windows\System32\slmgr.vbs /help
