If you've been using the 30-day version
of Microsoft Office 2010, here's a nice tip for you: the testing period can be extended for up to six months. Much like Windows
, the popular productivity suite contains a so called rearm function that gives you 30 extra days to activate the program. The command can be used up to five times, and if used at the end of each 30-day grace period, you can run Office 2010 for up to 180 days without entering an activation key.
