I am trying to update the build Cumulative Update for Windows 11 Insider Preview (10.0.26120.1542) (KB5041872).

However, whenever I attempt to download the update, it consistently gets stuck at 8%. When it reaches 8%, the CPU usage by the Windows Modules Installer spikes to 80-90%, causing the PC to become unresponsive and slow. The issue resolves after restarting the PC and pausing the update. However, the problem reappears as soon as I resume the update, making it difficult to use the PC smoothly. I have tried restarting the Windows Modules Installer and Windows update from the systems. But it still is not resolving.

I managed to fix it on my machine. I uninstalled the Security Update for Microsoft Windows KB5041872 and the Feature Enablement for Beta Channel Preview Update KB5037898. After the uninstall I checked for updates, and it downloaded a (repair) update. Once that updated was installed and the PC restarted, checking for updates resulted in once again trying to install the KB5041872 update which managed to pass the 8% mark and fully install within seconds.

    approximately 3-5 minutes. First, it goes to 6% and suddenly shows 100% and the other moment it contunues from 7 to 8% where the CPU usage suddenly peaks. and stucks there.

    I'm having an issue with the download part.
    It gets stuck at 8% and the CPU usage goes up to 100%. I've followed your instructions, but the problem remains. I've had to end the modules installer task from the task manager to reduce the load.
