Solved Answer

Windows updates are releases of new features, security patches, and bug fixes for the Windows operating system. They are designed to improve the performance and security of the system and are released on a regular basis by Microsoft.

It is important to keep your system up-to-date by regularly checking for and installing these updates. Some updates may require a computer restart to take effect.

Regardless of whether users have updates set to manual or automatic, they might experience the error at any time when the process is initiated.
