Hello guys,



I'm facing some issues with 2 Citrix servers cannot get the latest Cumulative Updates. They get installed until 99% and then roll back with the error "Windows couldn't install updates undoing changes" and reboots. Checked the build number afterwards and both have the 2019-02 CU installed.



  • Checked EventViewer and the error message seems to be 0x800f0922.
  • Checked services and App Readiness, Windows Update and Update Orchestrator were started and set on automatic
  • Made sure that .Net Framework is installed, checked System Partition and both had 31% Free Disk Space (~150-160mb)
  • Tried to install 2019-03 CU manually and got the same results
  • Both have 20 GB Free Disk Space on C:\
  • Windows Update agent was reset
  • DISM Repair and sfc run was used -> No corruption found
  • Performance counters were reset
  • SoftwareDistribution and catroot2 folders were renamed
  • Ran Windows Updater Troubleshooter


Not sure if I'm allowed to post any links or if you have any suggestions on how to upload the logs, I'm open to suggestions 😀

The WindowsUpdate logs are here : Link Removed



I'm literally out of ideas other than reinstalling the imaging which will upset the customer(backups, restores, reconfigure etc.)



Thank you in advance!

Adrian

Run the Update Readiness Tool: - Download and run the https://support.microsoft.com/en-us/help/4027322windows-update-troubleshooter to diagnose problems with the Windows updates. 3. Temporary Disabling Security Software: - Temporarily disable any third-party security software to see if it might be interrupting the update process. 4. Run Windows Update Manually: - Sometimes manually starting the Windows Update service can help. Open Command Prompt as Administrator and run the following commands:
Code: 
 net stop wuauserv net stop cryptSvc net stop bits net stop msiserver ren C:\Windows\SoftwareDistribution SoftwareDistribution.old ren C:\Windows\System32\catroot2 catroot2.old net start wuauserv net start cryptSvc net start bits net start msiserver
5. Review Windows Update Logs: - Review the Windows Update Logs thoroughly to identify any specific error codes or patterns that might help pinpoint the issue. 6. Contact Microsoft Support: - If the issue persists after trying these steps, it might be best to reach out to Microsoft Support for more advanced troubleshooting or a possible solution. I hope these suggestions help in resolving the issue with the Cumulative Updates on your Citrix servers. You can also provide more details or logs if needed, and we can further assist you in analyzing them.
