How to Solve Error Code 0x941

There are several troubleshooting steps you can take to resolve error code 0x941:

Run the Windows Update Troubleshooter

Windows includes a built-in troubleshooter designed to identify and fix common issues with the update process. To access it:

  • Press Windows key + I to open Settings.

  • Navigate to Update & Security > Troubleshoot.

  • Select Windows Update and click Run the troubleshooter.

Check for Disk Space Availability

Ensure you have enough free space on your hard drive for the Windows update files. Open File Explorer, right-click on your system drive (usually C:), and select Properties. * Check the available space in the General tab. If it's low, consider deleting unnecessary files or programs to free up space.

Temporarily Disable Antivirus Software

Temporarily disable your antivirus software to see if it's interfering with the update process. Remember to re-enable it after troubleshooting.

Reset Windows Update Components

Resetting Windows Update components can often resolve corruption issues:

  • Open Command Prompt as an administrator.

  • Run the following commands one by one, pressing Enter after each:

    • 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

  • Restart the services in reverse order:

    • net start wuauserv

Update Network Drivers

Outdated network drivers can cause connectivity issues that prevent successful updates. Visit your computer manufacturer's website or use Device Manager to update your network adapter driver.

Run System File Checker

The System File Checker (SFC) tool scans for and repairs corrupted system files:

  • Open Command Prompt as an administrator.

  • Type sfc /scannow and press Enter.

  • Allow the scan to complete and follow any on-screen prompts.

Perform a Clean Boot

A clean boot starts Windows with minimal drivers and startup programs, helping isolate potential conflicts:

  • Press Windows key + R, type msconfig, and press Enter.

  • Go to the Services tab and check Hide all Microsoft services. Then click Disable All.

  • Go to the Startup tab and click Open Task Manager. Disable all startup items.

  • Restart your computer and attempt the Windows Update again.

Download and Install Updates Manually

If automatic updates fail, you can manually download and install them from the Microsoft Update Catalog (link). Search for your specific update KB number and follow the instructions to download and install it.
