Hello Carl J Austin,
thank you for posting on the Microsoft Community Forums.
Error 0x80073701 usually indicates that there is a problem with the Windows Update components or the system files on your computer. Here are some steps you can try to resolve the issue:
- Run the Windows Update troubleshooter. You can do this by going to Settings > Update & Security > Troubleshoot > Windows Update.
- Clear the Windows Update cache. To do this, open Command Prompt as an administrator and type the following commands: 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
- Perform a clean boot. This will help you determine if any third-party software is interfering with the update process.
- If this issue still persists, you can refer to the solutions in Unable to install patch KB5039705, Win server 2019 - Microsoft Q&A.
Hope it helps.
Kind regards,
Lei
