+### UserInitMprLogonScript
+
+- `HKCU\Environment\UserInitMprLogonScript`
+
+This per-user registry value can point to a script or command that is executed when that user logs on. It is mainly a **persistence** primitive because it only runs in the context of the affected user, but it is still worth checking during post-exploitation and autoruns reviews.
+
+> [!TIP]
+> If you can write this value for the current user, you can re-trigger execution at the next interactive logon without needing admin rights. If you can write it for another user hive, you may gain code execution when that user logs on.
+
+```bash
+reg query "HKCU\Environment" /v "UserInitMprLogonScript"
+reg add "HKCU\Environment" /v "UserInitMprLogonScript" /t REG_SZ /d "C:\Users\Public\logon.bat" /f
+reg delete "HKCU\Environment" /v "UserInitMprLogonScript" /f

+Get-ItemProperty -Path 'Registry::HKCU\Environment' -Name "UserInitMprLogonScript"

+Remove-ItemProperty -Path 'Registry::HKCU\Environment' -Name "UserInitMprLogonScript"
+```
+
+Notes:
+
+- Prefer full paths to `.bat`, `.cmd`, `.ps1`, or other launcher files already readable by the target user.
+- This survives logoff/reboot until the value is removed.
+- Unlike `HKLM\...\Run`, this does **not** grant elevation by itself; it is user-scope persistence.
