When a "scheduled update" is applied to an operating system image, it uses the C: drive by default. It stores a copy of the WIM fil in C:\ConfigMgr_OfflineImageServicing. Needless to say, this might not be where you want it. You can change the location by editing the WIM data to reflect the new drive letter.
This shows how to remotely trigger SCCM compliance settings.
The default is 60 seconds and can't be changed through the GUI.

Using SCCM and compliance settings, you want to search for old profiles (unused for 90 days). You want to make sure only Domain (not local ) account profiles are wiped out. And you want an exception list, stored in an AD group. When found, you want to report on Compliance (if no outdated profiles) and you want to remediate if found.
Based on the systems in a collection, this will wakeup all of them using the 1E server.
I found some systems where WMI was broken and needed a way to test if this was the case. Unfortunately the WMIC command doesn't set errorlevel, so it got a bit tricky.
