Sets InitialKeyboardIndicators = 2 under HKCU\Control Panel\Keyboard, so the numeric keypad is active the moment you reach the sign-in/desktop instead of you having to press NumLock every boot. Most useful if you type your PIN/password using the number pad. (Most reliable with Fast Startup disabled.) Takes effect on next sign-in. Reversible.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
