// This is a registry driven UI that walk through the part of the

// Note that registry values can be localized, so internation versions
// have to localize the INF file so that setup will set the registry
// with the right text.
//
// Here is how the registry key looks like,

// HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\AdvancedOptions\
// GroupKey1\

// ; default to Software\Microsoft\Windows\CurrentVersion\Explorer\AdvancedOptions
// ValueName="reg value name."
// CheckedValue=... ; value for this radio button,
// ; if the value is platform dependent, use one of the following two instead
// CheckedValueNT=... ; if the value is platform dependent
