.Synopsis
Auto create a VM from your MDT Deployment Media
.DESCRIPTION
Given an MDT Litetouch Deployment Share, this script will enumerate
through all "Offline Media" shares, allow you to select one or more,
and then auto-update and auto-create the Virtual Machine.
Ideal to create base reference images (like Windows7).
.NOTES
IN Addition to the default settings for your CustomSettings.ini file,
you should also have the following defined for each MEdia Share:
SKIPWIZARD=YES ; Skip Starting Wizards
SKIPFINALSUMMARY=YES ; Skip Closing Wizards
ComputerName=* ; AUto-Generate a random computername
DoCapture=SYSPREP ; Run SysPrep, but don't capture the WIM.
FINISHACTION=SHUTDOWN ; Just Shutdown
AdminPassword=P@ssw0rd ; Any Password
TASKSEQUENCEID=ICS001 ; The ID for your TaskSequence (allCaps)
Also requires https://github.com/keithga/DeploySharedLibrary powershell library
