Hello, I have a problem when updating 2023-08 Cumulative Update Preview for Windows 11 Version 22H2 for x64-based Systems (KB5029351), it downloads the update and starts to install, but it gets to 25% and stops there. Then it says some error during installation. What should I do? could be the problem?
There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x800705b4)

Hi,

Thank you for posting in Microsoft Q&A forum.

Are you using SCCM or WSUS to deploy the update? The error code (0x800705b4) typically indicates a timeout issue or some other interference during the update process. The reasons can vary, but they often relate to software conflicts, corrupted update components, or even system file issues. Here are a series of troubleshooting steps you can follow to resolve the problem:

1,If you have any antivirus software or firewall, disable them temporarily and try the update again.

2,Open a Command Prompt as Administrator.

Enter sfc /scannow.

Let the process complete, then restart your computer and try the update again.

3,Open a Command Prompt as Administrator.

Stop the Windows Update service by entering: net stop wuauserv.

Navigate to C:\Windows\SoftwareDistribution\Download and delete all the files and folders inside.

Restart the Windows Update service: net start wuauserv.

Retry the update.
