try booting safe mode:

• log out , go sign in screen.
• hold down shift key on keyboard while clicking power button on screen.
• continue hold down shift key while clicking restart.
• continue hold down shift key until advanced recovery options menu appears.
• click troubleshoot
• click advanced options
• click startup settings
• click restart
• press (4) enable safe mode
• wait while windows 10 starts in safe mode.
• log in

proceed uninstall update.
