HI,
I'm planning a new lab environment and due to all sorts of reasons I have limited disk space available for the various (10+) machines. To overcome the disk space problems we're going to build the environment using differencing disks on Hyper-V 2012.
However, we want to keep the lab up-to-date with Windows Updates. I'd like to inject these updates into the parent disk and not have all the updates in the child disks of the various machines.
I have 2 questions about this scenario:
1. Is it at possible to use a non sysprepped disk as a parent disk (I've used differencing disks before but always worked from a sysprep image)?
2. If the above is possible the following question would be if it's possible to update the parent VHDX (or replace the parent VHDX with an updated version) without breaking the configuration of all the depending machines?
