Here’s a handy set of commands when using in particular Virtual Machines with a ’demo’
environment.
We certainly create images for my students to take away with them and the common question
is:
“When will this OS expire?” or more likely on the 3rd day of a 5
day course I get the error popping up stating the OS has expired and will shutdown
every 2hrs.
To know when the OS may expire from the command prompt:
c:\slmgr -xpr
To possibly EXTEND to trial period for the OS
c:\slmgr -rearm
(note – you can only get away with this a few times)
If this fails, you can always jump to MS and try and get a trial key off their site.
