This is a keyboard layout for windows, created with Microsoft Keyboard Layout Creator.
It adds support capital letters À, Ì, Ò, Ù,È and É, as well as ` and ~. Those characters are reachable as they are in standard Italian keyboard layout for Linux distributions.
To install the font just run setup.exe in the layout01 folder.
In order to completely remove the keyboard is not enough to remove it from the active languages: you have to uninstall it from the Add/Remove Programs windows tool.
