- It's curious about the April 7, 2025 date when the updates were released on April 8.
- If the updates are manually installed without being connected to the internet (KB5055683 and KB5055518 are in the catalog, KB5057589 can be downloaded while installing with Windows Update and then tried again), the error doesn't occur.
- Sometimes, even without Windows Update finishing downloading the updates and without having any installed, just restarting during the download causes the error.
Conclusion: The three updates released on April 8 don't have any issues. It must be that Windows Update itself was updated internally on April 7, and there's a bug. These internal updates don't appear in the update history.
Servicing Stack 10.0.19041.5676

Windows Update can update internally without appearing in the update history as an update with a KB (Knowledge Base) identifier.
These internal updates affect the Windows Update client itself and sometimes maintenance system components (such as the Windows Update service, the installation engine, or the Background Intelligent Transfer Service (BITS).
Characteristics of these updates:
✅ They do not appear in the update history as KBxxxxx.
✅ They can be installed silently (without asking for permission or displaying a warning).
✅ They can change the behavior of the update system, including how future updates are downloaded and installed.
✅ They are sometimes recorded in Event Viewer or in internal log files (such as WindowsUpdate.log or CBS.log), but not in the usual Update History section.
✅ Some versions of these updates are called “Update Stack Packages” or “Servicing Stack Updates (SSU)” and may be packaged or disguised as part of other updates.
