The problem
When you decommission a workstation, you need to remove it from four systems: AD, SCCM, Intune and Entra ID. Forget one and the consequences are real.
- Forget Intune — the device keeps reporting compliance status. Forever.
- Forget Entra — the device still consumes an M365 license.
- Forget SCCM — the policy keeps pushing to a phantom record.
- Forget AD — the computer object lingers, eventually flagged as stale.
Doing all four manually takes 5-10 minutes per device — and you'll forget one. Eventually.
