The most common reference to "Win L" is the global Windows keyboard shortcut: . Function : Instantly locks your computer.

: To resume work, simply log back in with your password, PIN, or biometric. Why is it a .ZIP file?

: Protects your data when you step away from your desk.

: Scripts used by IT administrators to enforce or block screen locking across multiple PCs.

: Files ending in .reg that enable or disable the "Lock Computer" function.

Exercise extreme caution if you found a "Win L.zip" file on an unofficial website.
