I am iniating a project where I am going to have to setup potentially 2-300 new VMs to upgrade existing infrastructure.<\/p>\n\n\n\n
They’re all based on Hyper V so it makes sense to script this so it can be quickly deployed either one at a time or in bulk with the ISOs attached and ready to go!<\/p>\n
So this would be better supported by a VHDX with a SYSPrep already created and a working OS in there so that the machine could be quickly stood up, patched and ready to roll!
That’ll be in a later itteration.<\/p>\n
Onward… with the code!\u00a0<\/p>\n
