Extend Evaluation Period of windows server 2016

Today I came across an issue in my Lab where my windows 2016 server evaluation license got expired. Here we will see how to extend the Evaluation period of windows 2016 server.

As you can see in below screenshot my windows evaluation license has been expired.

To extend the evaluation license follow the below procedure.

  • Open an elevated command prompt.
  • Type following command slmgr -dlv or cscript.exe %windir%\system32\slmgr.vbs /dlv you will get output as below.


You can see there are 5 Windows rearm count are remaining so you can extend it for 5 more time for 180 days each time.

  • Run the below command to rearm it

Slmgr -rearm or cscript.exe %windir%\system32\slmgr.vbs /rearm


  • Restart your system now.
  • After the system restart the evaluation period will extend for another 180 days.

You can also verify the rearm count any time by running the command slmgr /dlv as we run in very first step.
