The process wlms.exe has initiated the power off of computer

I was getting random shutdowns of one of my virtual machines hosted in azure... I thought it was something related to azure but no.

I had a look to the shutdown log and found out this:

A fast googling told me that in order to stop the VM from shutting down I needed to activate it :)
