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.
Having high CPU usage and lag whenever trying to update WIP "Cumulative Update for Windows 11 Insider Preview (10.0.26120.1542) (KB5041872)" build

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.

2024-09-08T16:32:41+00:00 It worked for me to stop the process TiWorker.exe, install the KB5041872 update offline, restart and check for updates with Windows Update to check if it worked.
The only thing I can add is another link to the offline installer: http://1.117.76.68/Windows11.0-KB5041872-x64.msu](http://1.117.76.68/Windows11.0-KB5041872-x64.msu "1.117.76.68") (as shared in the comment by [Yang.Z - MSFT in the issue Assistance Required: Download Error 0x80070005 for Windows 11 Insider Preview Update).

2024-09-08T14:58:41+00:00 I can concur that this worked for me. I'm not trying a download site outside of Microsoft. This method appears to be working. I'll come back with a final reply when it's all installed without issues, but so far this has actually progressed and done something.
*I tried posting a screenshot but it keeps failing. Ce la vie.
The difference now, is that this update installs; "Windows 11 Insider Preview 10.0.26120.1542 (ge_release_svc_betaflt_upr) (repair version)"
