How to extend Microsoft Office 2010 trial period in Windows XP

Microsoft Office 2010 is packed with good feature that will make your life easier. One of it's I like most is the ability to save document to PDF file format without additional plugin or third party converter. The same thing goes to Office 2010 Trial Version. The only sad thing is when the trial period is over.

Now, there's a simple and easy way to extend or I would say reactivate Microsoft Office 2010.

Here's how.

In general, you need to run an executable program called OSPPREARM.EXE. This file is located in C:\Program Files\Common Files\Microsoft Shared\OfficeSoftwareProtectionPlatform>

Here's the detail

1. Run the command prompt
In Windows XP
- Click start - Run - type "cmd" and press enter.

In Windows Vista or Windows 7 (command prompt must be run as administrator)
- Go to Start menu, All Programs, Accessories, right-click on Command Prompt and select Run as administrator.

2. Go to OSPPREARM.EXE location and run the program
- In the command prompt, type " cd C:\Program Files\Common Files\Microsoft Shared\OfficeSoftwareProtectionPlatform" 
- type "OSPPREARM.EXE" and hit enter.

After a while "Microsoft Office rearm successful." will appear. That's it you're done. Now you can use Microsoft Office 2010 for another 30 days.

* You can run OSPPREARM.EXE 5 times only. After that it will display an error which means you will not be able to extend you Office 2010 trial period. My suggestion is, run this executable program only when your Office 2010 trial is expired.
