Extend grace period of Microsoft Office 2013
Sometimes we need to extend the grace period of Microsoft products including Microsoft’s flagship product – Microsoft Office 2013. Here are the steps how to do it.
Run command prompt as Administrator
Go to location: %ProgramFiles%\Microsoft Office\Office 15
Type this command: cscript ospp.vbs /rearm
YES!!! You are done. Your office is activated again as you have extended your grace period. You can maximum do it for 5 times.
