Every so often I will get the “emergency” request for a Windows Server machine and either it will take too long to purchase a license or it’s only a trial to check something. Of course, the server is established and all is forgotten.
One hundred and eighty days later; an issue is raised over the server being offline. A quick check and of course the license has expired so the machine will start regularly shutting itself down.
The test of course is not over so do we extend it or get a license? The license idea is rejected to we can only extend the trial period.
Microsoft understands these issues and gave a simple way to extend a trial:
- Start a command prompt as administrator
- enter : slmgr.vbs /rearm
- The system will need a reboot for the extension to begin.
A new period of 180 days will be displayed and you can do this 2 more times.
