Windows 10: How to Lock (not sleep) laptop on lid close?
As far as I know, there is no built-in function to achieve this. But you can do this using a third party tool.
One of them is LapLock. This program is a lightweight (<50KB), open source tool and it's developed by Etienne Dechamps.
Download the program - https://github.com/dechamps/laplock/releases
(Download the latest laplock.exe release)
Open the Windows Startup folder by using this run command - '
Add laplock.exe to your Startup folder.
You can also use Lid Lock to do this.
Set "Do Nothing", lock your laptop using Windows key+L, and then you can close the lid.
- Capture the close lid event.
- Trigger a lock-screen event.
See: Capturing laptop lid closing event in windows?, and Command-line (cmd) command to lock a windows machine.
From those sources, we can use
GUID_LIDSWITCH_STATE_CHANGE to detect the trigger, and run:
from the command line to send a lock screen request to the machine.
I don't know what compilers you have available, or what languages you know, but this information should help you set up a program to do it for you.
I don't use Windows myself, so I can't build or test it for you.
