With the help of Windows 10 in-built troubleshooter option, clear update cache and restart or reboot the Windows update services, etc one can fix the latest Windows 10 update stuck.
Press together ‘Ctrl+Alt+Del’ on your PC keyboard to let the update install successfully.
If that doesn’t work, then shut down your Windows 10 because a force restart solves the problem most of the time.
Make sure to restart without external hard-drive or USB flash drive
Once restarted ‘End all program’
After that download and run ‘PC Repair Tool’
