I have already written about downloading Microsoft Office 2010 before. Normally Microsoft Office comes with a 30 day trial. After the trial period expires, Microsoft Office 2010 has to be purchased in order to use it.

Rearming is a method to extend the trial of Microsoft Windows and Microsoft Office up to one month. Previously I have written about using Windows 7 for 120 days using the rearming technique. Today I want to write about rearming Microsoft Office 2010 so that it can be used beyond the trial limit of 30 days.

microsoft office 2010

When the trial period of 30 days is about to expire, just run command prompt with elevated permissions and then go to the following folder:

C:\\Program Files\\Common Files\\microsoft shared\\OfficeSoftwareProtectionPlatform

Run OSPPREARM.EXE from the above folder and it will extend the trial of Microsoft Office 2010 by 30 days. You can use this rearm technique 5 times in total making the total days to run the trial to almost 6 months.
