When Windows 11 attempts to install cumulative update KB5078883 (OS Build 22631.6783) for Windows 11 version 23H2, the process can sometimes freeze, fail with an error message, or repeatedly restart without applying the update. This issue primarily impacts devices running Windows 11 version 23H2 trying to update to the March 10, 2026 build. Update failures usually happen when cached installation files become corrupted in memory, background servicing processes hang, or system storage conflicts prevent Windows Update from completing the operation.
When KB5078883 gets stuck or fails to install, your PC may display error messages during the download phase, hang indefinitely at specific percentages like 20% or 100%, or attempt to install only to roll back changes upon reboot. Fortunately, you can resolve these installation hangs using built-in Windows diagnostic and maintenance tools. Follow these step-by-step methods ordered from the simplest fix to more comprehensive system recovery options.
Method 1: Run the Windows Update Troubleshooter
When to use this method: Use this as your very first step whenever KB5078883 hangs during downloading or fails with a general error code. This automated tool checks background update services, resets corrupted temporary configurations, and verifies system update status.

- Locate Windows Update near the top of the list and click the Run button beside it.
- The screen will display an active diagnostic window scanning for issues with update components and pending system operations.
- If the troubleshooter identifies a problem, click Apply this fix when prompted on the screen.
- Once the diagnostic process completes and displays Troubleshooting has completed, close the window and restart your computer.
After your computer restarts, navigate back to Settings > Windows Update and click Check for updates to see if KB5078883 downloads and installs completely.
Method 2: Reset update services using the Get Help app
When to use this method: Use this method if the built-in troubleshooter does not resolve the issue or if KB5078883 gets stuck repeatedly at the exact same percentage during installation. The Get Help app runs guided automated routines to repair update components.

- Once the troubleshooting sequence finishes, close the Get Help app and perform a complete restart of your system.
After rebooting, check Windows Update again to verify whether OS Build 22631.6783 installs successfully.
Method 3: Clear temporary update files using Storage settings
When to use this method: Use this step when stored update files for KB5078883 become corrupted on your hard drive or when temporary cache files block Windows Update from finalizing installation files.
- Open Settings from your Start menu and select System from the left sidebar.
- Click on Storage on the right pane to open system storage management.
- Wait a few moments for the screen to calculate storage usage, then click on Temporary files.
- Place a checkmark next to temporary update files and delivery optimization files while leaving your personal download folders unchecked.
- Click the Remove files button located near the top of the selection list and confirm the prompt on the screen.
- Optionally, launch the PC Health Check app from your Start menu to check overall device storage health and performance.
- Restart your computer so Windows can rebuild the temporary update cache properly.
