Sysprep Requirement for Windows VM Templates
The requirement for running sysprep when preparing VM Templates (with Windows) looks a bit confusing, because as soon as you start converting finalized VM, the status changes to 'Sysprepping...'.
If VMM could do sysprepping on it's own, I'd like to be able to skip doing this step in my Task Sequence, because one of the last steps I'm doing is applying some hardening GPOs, which in turn, cause sysprep to succeed only after a subsequent reboot (and automating one is quite a challenge as apparently MDT doesn't like something that's being touched by the hardening policies)

But it can - that's what it does at that step - it runs sysprep, as I understand. I create my templates relying only on SCVMM's sysprep and everything works fine.
