+
+## Root cause 
+
+This error occurs because the OS is in a pending servicing state and the TrustedInstaller service can't clear it due to corruption in the *Transactional Entries* folder. This corruption prevents the completion of update installations and requires a system reboot to roll changes back.
+
+## Resolution
+
+Perform an [in-place upgrade](/azure/virtual-machines/windows-in-place-upgrade) on the Windows virtual machine.
