+# Troubleshoot "Shutdown in Progress" Windows error 0x8007045b
+
+## Symptoms
+
+When you install a Windows update, or during an OS upgrade, error code 0x8007045b (ERROR_SHUTDOWN_IN_PROGRESS) is logged in the Component-Based Servicing (CBS) log, ```output(%windir%\logs\CBS\CBS.log)```, or in the Setact log, ```output%windir%\Windows~BT\sources\panther\setupact.log```.
+
+These log entries indicate that the installer or a component detected an ongoing shutdown process. The troubleshooting steps in this article can help you resolve this issue effectively.
+
+### Symptom 1: Unresponsive installation
+
+The installation might experience a 15-minute time-out that causes the Trusted Installer to initiate a restart because of "CBS hang" detection. Upon restart, the installation is typically rolled back. When this issue occurs, the following entries are logged in the CBS log:
+
+**%windir%\logs\CBS\CBS.log**
+
+```output
+Info CBS Setting HangDetect value to 3 
+Info CBS Startup: will attempt a restart to recover.
+Info CBS Failed restart attempt. [HRESULT = 0x8007045b - ]
+Info CBS Startup: restart attempt failed, allowing the user to logon.
+Info CBS Startup: A system shutdown was initiated while waiting for startup to complete
+```
+
+**Error 0x8007045b**
+
+```outputERROR_SHUTDOWN_IN_PROGRESS winerror.h```: A system shutdown is in progress.
+
+### Symptom 2: Third-party service interference
+
+A third-party service triggers a restart during a Windows OS upgrade. When this issue occurs, the following entry is logged in the Setupact log:
+
+**%windir%\Windows~BT\sources\panther\setupact.log**:
+
+```output
+Info MIG Instantiating an ICbsSession9 interface
+Error MIG Failed to create CBS session 9. hr = 0x8007045B[gle=0x000003f0]
+%systemdrive%\$WINDOWS.~BT\Sources\Rollback\evtlogs:
+Information MM/dd /YYYY HH:mm:ss PM User32 1074 None
+The process c:\program files (x86)\netinst\mgmtagnt.exe (MACHINENAME) has initiated the restart of computer {MACHINENAME} on behalf of user NT AUTHORITY\SYSTEM for the following reason: Other (Unplanned)
+Reason Code: 0x0 Shutdown Type: restart Comment:
+Information MM/dd /YYYY HH:mm:ss PM EventLog 6006 None
+The Event log service was stopped.
+```
+
+## Cause
+
+This behavior is by design. It's not an error but an exception. This issue commonly occurs if the installation stops responding or experiences interference from a third-party component.

+
+## Resolution
+
+To resolve this issue, use the following methods, as appropriate:
+
+- Resolution 1: Nonresponsive system
+
+   If the system stops responding, try to increase the TrustedInstaller time-out value. For more information,  see the following Azure DevOps Blog article:
+
+   [Update Installation Error 0x800f0920](https://supportability.visualstudio.com/AzureIaaSVM/_wiki/wikis/AzureIaaSVM/1511786/Update-Installation-Error-0x800f0920-CBS_E_HANG_DETECTED?anchor=mitigation-1)
+
+- Resolution 2: Third-party service interference
+
+   Review the Setupact.log file to determine which third-party service causes the restarts. To prevent further system restarts, disable or stop the identified service.
+
+   > [!NOTE]
+   > Error code 0x8007045b can be safely ignored. Your troubleshooting focus should be on identifying the original error that precedes this code (error code 0x800f0920).
