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.

After uninstalling these two updates, another new update started downloading - Windows 11 Insider Preview 10.0.26120.1542 (ge_release_svc_betaflt_upr) (repair version)
After installing and restarting, another update started downloading - 2024-08 Cumulative Update for .NET Framework 3.5 and 4.8.1 for Windows 11, version 24H2 for x64 (KB5042098).
Another restart and finally the green check mark and message - You're up to date!

2024-09-10T20:07:54+00:00 I had the exact same issue. Just go to the microsoft catalog for updates and manually install the .msu!! Be patient with the install, if it gets hung up, just cancel and restart the manual install. I did this install after a refresh reboot before the 8% high cycle freeze.
