Configuring Licenses Using SLMGR

Microsoft’s command-line licensing tool is slmgr.vbs. The name actually stands for Windows Software Licensing Management Tool. SLMgr script allows users to query the current installation and see details about Windows 7/8 installation and its activation and licensing status.

Most of the licensing operating in Windows 8 can be done via a graphical user interface. If you’re a power user, you can access all options, flags and settings of the slmgr.vbs command script. To run the script, log on with a user account with administrator rights, and open an elevated Command Prompt window.

Options in SLMGR :

1.      slmgr -dli (display the current license information)


2. slmgr -dlv (stands for display license information, similar to -dli switch but with more information)


3.      slmgr -ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx (enter a new or replace the current product key with the new product key supplied at xxxxx-xxxxx-xxxxx-xxxxx-xxxxx)

4.       slmgr -xpr (shows expiration date)


5.      slmgr -ato (activate Windows 8 license and product key against Microsoft’s server)

6.      slmgr -skms activationservername:port (set the KMS server and the port used for KMS Activation)

7.      slmgr -upk (uninstall current installed product key and return license status back to trial state)

8.      slmgr -rearm (reset the licensing status and activation state of the machine)

9.      slmgr -ckms (clear the name of KMS server used to default and port to default)
