Answer 1

Run the Windows Update Troubleshooter.

Open Settings > Navigate to Update & Security > Troubleshoot.

Select Windows Update and click Run the troubleshooter.

Lack of adequate disk space can prevent updates from installing.

Open Command Prompt as Admin and copy-paste the following commands:

sfc /scannow

DISM /Online /Cleanup-Image /RestoreHealth

Resetting Windows Update components can resolve issues:

Open Command Prompt as Admin and run these commands:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

Rename the SoftwareDistribution and Catroot2 folders:

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

Alternatively:

1. Visit the Microsoft Update Catalog.
2. Search for KB5051974.

Answer 2

Hello,

Thank you for posting in Microsoft Q&A.

Based on the description, I understand your question is related to windows update.

This error can be caused by various issues such as corrupted files, inactive services, or interference from third-party applications.

Try disabling any active antivirus software temporarily and then attempt the update again. Run windows update trouble-shooter, reset windows update components.

Create folder C:\temp\cab

Download the update from Microsoft Update Catalog to C:\temp

Expand the .msu file to extract the .cab file by running below command in CMD:

expand -F:* C:\temp\{.msu file name with extension} C:\temp\cab

You will get a .cab file from last step, use the following DISM command to add package:

Dism /online /add-package /packagepath:c:\temp\cab\{.cab file with extension}

If there is no error, reboot the machine

Have a nice day.

Best Regards,

Molly
