This is the script I use to start virtual machines in our cloud environment. I write it down here for archive and sharing purposes.
It is based on the Azure RunAs automation account.
The only thing thing you need to do is to schedule this script daily.

.DESCRIPTION
Turns of virtual machines only office days.
