Can't disable WIN+L

[TheCase]

Hi,

I'm trying to disable Win+l combination to re-assign that keybind with something else. I don't mind if the user can lock their PC another way but just not via that keybind.

I have added in
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System

DisableLockWorkstation = 1

Yet I can still lock, any ideas why?

Thanks

Go to this and give it a try using the second method on the page
Disable/Enable Lock Workstation Functionality (Windows + L)

Doesn't work, strange works on other PCs.

Any chance it needs to be done for all identities/user accounts?
