How to Download and Install KB5034765 on Windows 11?

There are two methods to get this cumulative update – either through Windows Update or by manually downloading the standalone installer.

Option 1: Via Windows Update

Windows Update will automatically download and install the KB5034765 cumulative update in the background. However, you can also manually check for updates and install it:

  1. Go to Settings > Windows Update.

  2. Click on Check for updates.

  3. Once the update is found, click Download and Install.

  4. Restart your PC when prompted.


Option 2 – Manual Installation

You can also manually download the KB5034765 offline installers from the Microsoft Update Catalog if needed:

  1. Select your Windows 11 version (21H2 or 22H2/23H2)

  2. Download the .msu file

  3. Double-click the .msu installer file to install the update

The standalone .msu package can be useful for environments without internet access or to avoid Windows Update bandwidth usage. Make sure your device meets the prerequisites above. The manual installation procedure remains the same as automatic updates.

The update will be installed after restarting your device.

System Cleanup After Installing Windows Updates

After installing Windows updates like KB5034765, it’s good practice to run some cleanup commands to clear temporary folders and remove obsolete Windows Update data.

Open the Command Prompt as Administrator and execute the following commands:

DISM /Online /Cleanup-Image /AnalyzeComponentStore

DISM /Online /Cleanup-Image /StartComponentCleanup

This will analyze the component store and remove superseded Windows Update files.


The steps above will help reclaim disk space and keep your Windows 11 system running smoothly.

Uninstalling the Cumulative Update

If you face issues after upgrading to KB5034765, it is possible to uninstall the cumulative update package with a few steps. However, this reverts your Windows version to the previous unpatched state.

dism /online /remove-package /packagename:Package_for_KB5034765~31bf3856ad364e35~amd64~~22631.3155.1.5

Replace Package_for_KB503476531bf3856ad364e35amd64~~22631.3155.1.5 with your actual cumulative update package name discovered from the first command.

This will uninstall KB5034765 from your system fully. Follow it up with mandatory restarts.
