Virtual Machine Template
Patching and update the VM template should be possible from SCVMM console, and from the current VM template.
I mean it should be possible to convert the current VM template to a VM so we can apply patches and updates and then reconvert the VM to Template.
Automate the following: Select existing VM Template - Button for Upgrade - It creates new temporary VM - Log into temp VM - Install new MS and non MS software, install updates to existing MS and non MS software, install MS patches/hotfixes - Power down VM - Button for Create new VM Template from this VM. VM Template appears in Library ready to deploy new VMs from it.
And wouldn't be much more simple to have the posibility to convert templates to vms and then patch and update them and after that convert them to template?
Use a VM that gets connected as a managed computer to VMM. Then use connected wsus to vmm to update the VM.
Clone and set to template.
Its a short script to automate it.
