My Lenovo did the same thing. So, I restarted it manually. Then, I kept getting blue screens every time I tried to install that update. And once it was installed, the blue screens continued. NDU.sys issues.
So after trying all tie DISM and scannow stuff, I just uninstalled Malwarebytes and the blue screens stopped. I've had that problem before, which is why I decided to try that.
May not apply to you, but it's what worked for me. In a little while, I'll reinstall Malwarebytes and see how long before another snafu happens...
