Windows 7

Windows 7 - 30 day trial (or more?)


October 22 is the release date for Windows 7 and, although I have used the Release Candidate (Evaluation Copy) Build 7100 for some months now, it was my intention to start the 30 day trial period of the RTM version in the run-up to the release date.

Sometime last week a story appeared on the web about a bug in Windows 7 which allows you to extend the 30 day trial period, or as Microsoft call it 'Rearm' it, for another 30 days. The process can be repeated three times in all giving four months (approximately) or 120 days of free use before deciding to buy.

At the moment there are no actual discs available for Windows 7, only downloads, but when they do become available, regardless of which version you buy, you will have access to all versions including a 30 day trial period to try it.

To get the extension to the trial period is simple and is already in built into the system. I would not advise experimenting with it until it is close to expiring because it will reset the clock on the trial regardless of how many days left you have.

The easiest way to check how long is left on the trial is to right-click on Computer from the Start menu and select Properties. At the bottom of the page is Windows activation showing the number of days left before activation is needed.


The Bug

The thing I like about 'The Bug' is that it was built into the system by Microsoft so it is not some hack or crack found on a forum that could screw up your system and/or complicate your license agreement.

Before reaching the end of your trial period (Windows 7 any version) go to the Start menu and in Accessories right-click on the Command Prompt selecting 'Run as administrator'. In the Command Prompt type 'slmgr -rearm' (without quotes) and hit Return. Restart windows and check the properties page which will now show 30 days before activation is required.
