I have weird situation. My friend uses password with polish characters to log in into Windows. However while he was logged in he changed keyboard layout to US. Now when he tries to use "ł" character while entering password nothing happens.
How can I change keyboard layout to Polish without logging into Admin account?
HKEY_CURRENT_USER\Control Panel\Input Method\EnableHexNumpad
with a string value of "1" to enable hex code character input. How lovely! Apparently this is enabled by default in Mac OS.
