A broken system update that only succeeded on 20% of install attempts
My Windows 10 system has been failing to install a recent cumulative update, with the installation process only succeeding about twenty percent of the time and hanging or rolling back the rest, leaving my PC in a partially updated state that feels unstable and insecure. I've already tried running the Windows Update Troubleshooter, clearing the SoftwareDistribution folder, and manually downloading the update from the Microsoft Update Catalog, but nothing seems to improve the success rate, so I'm hoping someone can suggest a more reliable fix or help me figure out if this is a known issue with this specific update.

I’d reset the Windows Update path before trying again. Start with the Windows Update troubleshooter, confirm you have plenty of free disk space, and disconnect nonessential USB devices during the update.
Then check Update History for the KB number and error code. If Windows Update keeps looping, try downloading that same KB from the Microsoft Update Catalog and installing it manually. If it still rolls back, Event Viewer and the setup/update logs should show whether it is failing on drivers, servicing stack, disk space, or corruption.
Hi, I would start by resetting Windows Update components and then installing the latest cumulative update manually from the Microsoft Update Catalog. Before retrying, run DISM /Online /Cleanup-Image /RestoreHealth and sfc /scannow to repair the component store. If it still fails, the exact error code in Windows Update history or CBS.log will point to the real cause.
