+# Troubleshoot Windows Update error 0x800f0920
+
+**Applies to:** :heavy_check_mark: Windows VMs
+
+## Summary
+
+Error code 0x800f0920 indicates that the Windows Update installation process stopped responding. This issue occurs if the Trusted Installer service doesn't complete the installation within the default timeout period of 15 minutes.
+
+## Prerequisites
+
+For Microsoft Azure virtual machines (VMs) that run Windows, make sure that you back up the OS disk. For more information, see [About Azure Virtual Machine restore](/azure/backup/about-azure-vm-restore).
+
+## How to identify the issue
+
+Check the `CBS.log` for entries that resemble the following example:
+
+```output

+```
+
+## Cause
+
+This error occurs because the Trusted Installer service doesn't complete the installation process within the default timeout period of 15 minutes. This failure can cause a rollback and cancellation of the transaction.
+
+## Resolution
+
+For Windows-based computers, perform an [in-place upgrade](/windows-server/get-started/perform-in-place-upgrade#perform-the-in-place-upgrade). 
+
+For VMs that run Windows in Azure, see [in-place upgrade on the Windows virtual machine](/azure/virtual-machines/windows-in-place-upgrade).
