Windows 10: How to Lock (not sleep) laptop on lid close?

Question

If my laptop is plugged in I want closing the lid to automatically lock the computer, without putting it to sleep. I don't see an option to do this in Power Options:

Is there a hack to achieve this?

This is generally a bad idea: your laptop dissipates a good deal of heat through the keyboard, and if you leave the computer running with the lid closed, you risk overheating things. — Mark, Apr 12 '19 at 21:23
@Mark: ...and yet you can set it to keep running full blast when you close the lid, _without_ frying anything. — Vikki, Apr 13 '19 at 03:26

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.

Steps...

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 - 'shell:common startup'
Add laplock.exe to your Startup folder.

You can also use Lid Lock to do this.

thanks, this implementation pretty much sums up the answer by mazunki, uses GUID_LIDSWITCH_STATE_CHANGE – Kevin Dec 05 '19 at 00:57

Two steps:

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 RegisterPowerSettingNotification and GUID_LIDSWITCH_STATE_CHANGE to detect the trigger, and run:

rundll32.exe user32.dll,LockWorkStation

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.

The solution is simple, in options --> accounts --> Sign-in options: Require sign-in = Every Time

I do not see a "Require sign-in" option in that section. Below "Picture Password" I have "Dynamic Lock" ... "Privacy" ... but no *Require sign-in*. – feetwet Sep 07 '20 at 19:05

Very likely because of the Extended Display Option set for the Monitor. Set the display only to Monitor, it should work.
