Location, group and the names of its PCs
Renaming a group keeps its locations. Removing one moves them to "No group".
The limits for warnings and alerts: toner and drum, LTE data volume and hard disks. Printers whose drum is part of the toner cartridge (or unknown) never get drum alerts.
Maintenance window and what gets installed. PCs pick up changes with their next report.
Installs, then restarts when needed. Logged-on users see a warning first; after the restart the PC continues (up to 3 rounds). A PC that is off during the window waits for the next one: it never installs on Monday morning.
Install the agent once per PC; it updates itself afterwards.
The agent checks every 5 minutes and reports as soon as a printer is switched on, otherwise every 8 hours. Windows updates stay off until you switch them on for the PC. Uninstall from "Apps & features" like any program.
