How to Extend or Reset Microsoft Office Trial Period 30 to 180 Days

Microsoft offers to download and try Office products for 30 days without paying anything. After 30 days of the trial period, you have to pay and activate the license. But, there is a trick that you can use to extend Office trial without paying and use it for 180 days which is about 6 months. To keep using Office trial version for 180 days you can run a simple command 5 times on every 30th day of trial, this way you will gain 30 more days of trial for 5 times.

Extend Office Trial Period for 180 days

We already posted a guide to extending Windows 8 or 7 trial period, very similarly Office trial extends method works on subscription-based Office 365, older Office 2013 and 2010 as well. You don’t need to use any app to extend trial, just use ospprearm file in Windows built-in command prompt application. Let’s see how to extend the trial period for Office.

  • Press Windows+R keys type: %ProgramFiles% and hit enter key from the keyboard. This will open your Windows program files directory.
    run command program files
  • Now go to the following folder Common Files\Microsoft Shared\OfficeSoftwareProtectionPlatform
    Note: If you are using a 32-bit version of Office then the Program Files directory will be C:\Program Files (x86) and the other path will be same as above.
  • Once you are in the folder: OfficeSoftwareProtectionPlatform you will see a file OSPPREARM.exe. Here, press and hold Shift key from keyboard and right-click on the empty area and select “Open command prompt here” option.
  • In the command prompt windows type OSPPREARM.exe and hit enter to execute it.

You need to execute the file whenever you want to extend Office trial for 30 more days, remember you can only do that for 5 times to get 180 days of free Office trial period. You should buy a license if you do use Office products regularly.

Hi. I clicked on “run as administrator” and nothing happened. Does that mean it’s all good?
