I love powershell. I created a little script to deploy multi VM based on a Windows Template throug CSV file.
It’s create a computer account at the specfified ou. He greates also a Domain Local Group for management. (It used in the customization not specified here)

#Version: 1.1
#Date: 08-05-2018
#ChangeLog:
# V1.0 – Module Active Directory
# – Module VMware PowerCli
# – Active Directory Computer Account, Group
# – Host Selected from Cluster with Least Memory
# – Storage selection based on volume with most free space
# V1.1 – Added Harddisk 1&2
# – Changed porte group other vlan
