The Preload subkey stores the codes for each keyboard layout chosen by the user. Windows 2000 uses this information to restore the keyboard layout when the user logs back on.
Each entry in the Preload subkey represents a keyboard layout selected by the user where the name of the entry is a decimal number beginning with 1. The 1 entry identifies the user's default layout.
To change the keyboard layout, double-click Keyboard in Control Panel. Click the Input Locales tab, and then click the Add button in the Installed input locales box.
