The question I was originally asked was, “How do I bring up the soft / on-screen keyboard when a Surface Book is locked, so that I can press CNTL ALT DEL?”. This took me some time to figure out… but I got it and it is easy.
If you want to press CTRL ALT DEL on a Surface or Surface Book 4 without a keyboard, you simply:
- Press and HOLD the POWER BUTTON down
- Press the VOLUME DOWN button
This technique can be used as a substitute for CNTL ALT DEL anytime, including when the Surface is not locked to bring up Windows Security and then start a TASK MANAGER:
If you have a Microsoft Surface you will also likely be interested in how to get into the BIOS and how to RESET your Surface.
