The procedure is nothing but an Office command, OSPPREARM which is located in Windows Program Files drive. By running the command for one time you will be able to extend Office 2010 trial period to another 30 days. By this way you can prolong the trial period total five times. That means your trial period can be extended up to six months including the initial 30 days.
