How to Extend Your Office 2013/365 Trial to 180 Days
 

In recent years it has become common for Microsoft to release trial or preview versions of its big-name products. This has been the case with Windows 8 as well as Office 2013 giving consumer the chance to try before they buy. If you downloaded the trial version of the suite, you can gain some extra try-out time with this handy hack.

The trial version of Office 365 is only meant to be used for 30 days. After this time you are expected to by a license or stop using the software. In practice, Office does not become unusable, but instead enters a ‘reduced functionality’ mode.
