## Changes
**Article update** (`articles/windows-mdm-setup.md`)
- Adds "Migrating from another MDM solution" subsection under **Manual
enrollment** with overview of common migration issues and links to
remediation scripts
**New scripts** (`docs/solutions/windows/scripts/`)
- `reset-mdm-enrollment-flag.ps1` — Resets MmpcEnrollmentFlag blocking
MDM status after migration
- `remove-stale-mdm-enrollment-records.ps1` — Clears orphaned enrollment
GUIDs, AAD discovery cache, and MS DM Server cache
- `fix-workplace-join-configuration.ps1` — Re-enables
Automatic-Device-Join task and configures Workplace Join policies
- `remove-unreachable-wsus-configuration.ps1` — Removes unreachable WSUS
server config that breaks Windows Update
## Context
Customers migrating Windows hosts from Intune to Fleet have been hitting
recurring enrollment issues, MDM status stuck on "Off," enrollment
errors (`0x80190190`, `0x8018000a`), and Windows Update breakage from
leftover RMM agents. These scripts consolidate the workarounds from
multiple customer engagements into self-serve remediation that can be
deployed via **Controls > Scripts**.
