On the new Persistent pool we are using a power off power setting for VMs. Meaning after they disconnect it logs them off after an hour. Then after that hour it goes into shut down mode. It should power on again when they request access to their machines.
I mention it because of two things, one how will this effect patching? Two, if this works we should probably change your pool to the same, 1. lowers the security footprint, 2. machines are not always used and can give us a great savings on resources.
Team- Please suggest me the best way to patch the Persistent Instant Clone VDI with help of SCCM.
