I recently built my PC using new-gen parts, so my hardware is as up-to-date as it gets. The amount of time and effort required for something as simple as updating a PC is mind-boggling. I spent hours trying to install the Windows 11 24H2 update, only to repeatedly hit the 0x800f0838 error. After trying every single troubleshooting step with no success, I finally had to perform an in-place upgrade of Windows 11.

The upgrade process itself went smoothly, but when it came time to install the update after the upgrade, the same one that had failed before, it went from 100% complete back to 0%, before finally climbing back to 100% and completing successfully. It turned out the root cause was a missing prerequisite update, which is incredibly frustrating because I make sure to keep my PC, drivers, and updates current.

While researching this, it became clear this is not the first time users have faced similar issues. Updates with the same problem have been reported as far back as 24H2-9 through 24H2-12.

Why are users forced to spend hours troubleshooting, restarting, and ultimately resorting to something as drastic as a system reinstall just to get an update working? If an update requires a prerequisite, why isn’t it flagged or installed automatically? Microsoft, this process needs to be fixed. Updates should be seamless, not a multi-hour ordeal for users who are already doing everything they can to keep their systems up to date.

2024-11 Cumulative Update Preview for Windows 11 Version 24H2 for x64-based Systems (KB5046740) stuck at 81% for hours
My newish Dell XPS i7 laptop has been stuck on installing KB5048162 at 0% for hours. This install came up right after rebooting with the full 24H2 update. Task manager shows that Windows Installer Module Worker is running, and occupying hundreds of MB of RAM, but close to 0% CPU. Out of frustration I rebooted once so far, and the installer started over again, and again is stuck at 0% installation progress after an hour. More on reddit.com

Hello Neil,

Thank you for reaching out to the Microsoft Community and I'll be glad to assist you today.

Windows updates are generally downloaded and installed automatically. If you choose to delay the Windows 11 24H2 feature update or haven’t received it yet, you may still receive cumulative updates for 24H2 automatically (after the 24H2 update) through Windows Update, depending on your PC’s update history.

If you choose to manually download and install packages from the Microsoft Update Catalog website, it's recommended to install only the package that is supported for your PC. When you search for a KB file in the catalog, you'll typically see two or more results: one for X64-based devices and another for ARM-based devices. Find out the correct architecture for your PC model and install the cumulative update that is supported for your system.

This manual installation process is usually not recommended if automatic updates are working properly.

To find your Architecture - Go to Settings > System > About. (System Type).

If my understanding is wrong, please provide some more information about your issue.

I hope this information helps. If you have any questions, please let me know and I will be happy to help you further.

Best regards,

Gunasekar N

Thank you for the reply. But you haven't understood my question. I perform the monthly updates myself in a manual manner, as I have always have.

As I have said, I have currently running Windows 11 23H2 and I download the CUs manually from the Windows Catalog. Where this months CU for Windows 11 23H2 looks like this, with one MSU file available;

When I look at this month's CU for the Windows 11 24H2 Catalog download page, I see this;

When I look at the Microsoft Support documentation for the manual installation steps, I see this;

This clearly says that these updates need to be installed in this order. However, as per my question above, I have asked the following;

  • Do I install both updates in this order and then reboot/restart?

Or

  • Do I install the first update, restart Windows and then install the second update after the restart, follow up with a second restart?

Many thanks in advance,

Kind regards

Neil
