virtualbox auto shutdown answer below:
In the Windows guest, open the command prompt and enter
slmgr /rearm
(not –rearm as cited in that post, since this is Windows). You can do that up to twice apparently, to extend by 30 days each time. Apparently the iectrl tool from ievms also works but I didn’t try that.
The above code worked for when my virtualbox virtual machine keep shutting down very often.
So the above code simple to overcome this issue folks..
I hope this will help someone like me, who are facing the issue.
## Cheers Guys
