If there are already pending updates or downloads in the queue, it might interfere with the current update.Problems with the Windows Update Service itself, such as misconfiguration or a service that isn’t running properly, can prevent updates from being downloaded.
These files may need to be repaired or replaced for the update to proceed. If there isn’t enough space, the update process may get stuck. Slow or unstable internet connections, insufficient disk space, conflicting external devices, and corrupted system files are some frequent culprits. A Windows 11 update may get stuck during downloading due to various common reasons.
