Rearm trial windows OS

When installing Windows OS as a trial to test out the operating system, you get a free 30 day trial. Sometimes you need a little extra time to make sure everything is working as should and before you shell out for the licence key.

Microsoft allows you 3 trial periods (totalling 90 days), on your final trial day open up a terminal window in Administrator mode and run

slmgr.vbs -rearm

After that you’ll be required to reboot the computer and your trial will then be extended another 30 days.

There is also a registery modification you can do to allow up to 8 rearms but i’ve never tried it.
