Windows 10 Lock Screen (Solved)

[Skeletor]

Hi Virtual People, 

I'm trying to lock my screen in Windows 10 but to no avail. 

Has Windows 10 forbidden this feature? 

Send("#l")

Above code does not work. Even sending Ctrl Alt Del does not work nor as an Admin. 

Note: I want to lock my screen, not log off. Thanks for been kind.

Yes, Microsoft has blocked sending CTRL+ALT+DEL for what should be painfully obvious reasons. For simply locking the screen you can do something like this:

ShellExecute("rundll32.exe", "user32.dll,LockWorkStation")

You can also use the _WinAPI_LockWorkStation function in the AutoIt included UDFs.  

#include <WinAPISys.au3>
_WinAPI_LockWorkStation()

Moved to the appropriate forum, as the AutoIt Example Scripts forum very clearly states:

Moderator @JLogan3o13, I'm interested in the comment you made. Can you please elaborate the "painfully obvious reasons" part. 

Thank you kindly for your suggested script, @AdamUL as well as you for yours...

Security. Plain and simple

Thanks EarthShine

The CTRL ALT DEL combo on the start is done so someone could not fool you with a fake one back in NT 4 days and has been ever since. I think MS allows an admin to turn that off but I never would. It's also to defeat automated logons

Think about what someone with nefarious intentions could do if the CTRL+ALT+DEL keys could (easily) be simulated? It should be evident why Microsoft would not want your average user to be able to do this.
