Here is a step-by-step guide to finding the cause of the issue:
- Check for updates, as an update may have caused the issue.
- Check Devices. In your device manager, make sure everything is up to date, and all devices are properly connected.
- Disable Autosave. Go to Device settings and turn off autosave enabled software, which may interrupt shutdown processes.
- Test in Safe Mode. Try to perform a shut down in safe mode by restarting your computer and pressing 'f8' to access the start-up menu.
- Turn off unnecessary applications running in the background. Open Task Manager to identify any additional programs that may be running.
