Dedup Device Names Scheduled

Detect and rename duplicate Intune device display names using a prefix and random suffix

Description

This scheduled runbook queries all Intune managed devices and identifies devices that share the same display name. For each set of duplicates, the most recently enrolled device is renamed to a generated name consisting of a configurable prefix followed by random digits padded to the specified total length, and that name is persisted in the matching Windows Autopilot device object. An optional OS filter restricts processing to a specific platform (Windows, macOS, or other); when set to All, devices of every platform are evaluated.
