From another post ( In the i386 folder the following files exist: hivecls.inf -- creates the settings in HKLM\SOFTWARE\Classes (HKCR) hivedef.inf -- creates the settings in HKU\.DEFAULT -- also creates the settings for the default user profile hivesft.inf -- creates the settings in HKLM\SOFTWARE hivesys.inf -- creates the settings in HKLM\SYSTEM ) (editing these prior to build sets the mods at OS install) under hivedef.inf the setting: HKCU,"Control Panel\Keyboard","InitialKeyboardIndicators",0x00000002,"0x80000000" HKCU,"Control Panel\Keyboard" - Regisrty Path InitialKeyboardIndicators - Value Name 0x00000002 - I am guessing this is the Data Type. (This is what I am trying to determine, a list indicating the Type) 0x80000000 - Value for the Value Name (0x20000000 turns NumLock on by default in the above string) Does anyone have a reference for this?
