Most of us working in IT Infrastructure management and
service management industry would have worked upon evaluation versions of
operating systems for test purposes most of them come with expiry period of 60 days and after that they
might behave differently ; like it may forcely boot or screen might go black
etc.
In such situations we can go for extending the OS evaluation
period for around 240 days wiht rearm command .But don’t use the rearm command until
and unless your evaluation period is finished else it might waste the remaining
evaluation period. Hence it is advisable to check the remaining evaluation
period before we go for rearm command.
In order to check how much of evaluation period is remaining
please perform following steps on your system (Here I was using Windows Server
2008 R2)
1. 1. Go to START type CMD right click on CMD and
select Run as administrator for elevated privileges
h 2. A prompt would appear shown as below click on
yes
3. Now type slmgr.vbs –dli (software licence manager command; -dli
Display license information)in command prompt which would return message from
windows script host something like this which tells how many days are left with
evaluation period
4. If it shows very less time left with evaluation
period then you can reset the evaluation period to additional 60 days as a
grace period with rearm (rearm: Reset activation timer and initialization) command
as follows
You are done and good
to go additionally if you want to check the grace period expiration details for
that system you can type slmgr.vbs –xpr which will provide you the expiry details of the grace
period.
