How to resolve the rundll error encountered during startup after updating to Windows 11?
After a system update, I am prompted with "rundll error - specified module not found" every time the computer starts up. How can I troubleshoot and fix this?

The "rundll error - specified module not found" message after a system update indicates that your Windows is trying to load a DLL file during startup, but it can't find the specified module. This can happen due to missing, corrupted, or improperly registered DLL files, especially after system updates.
