Sets the geographical location identifier for the user
_WinAPI_SetUserGeoID ( $iGEOID )
|$iGEOID||The identifier for the geographical location of the user (GEOID).|
This function writes to the registry the geographical location for a particular user instead of an application.
This action affects the behavior of other applications run by the user. As a rule, the application should call this
function only when the user has explicitly requested changes, but not for purely application-specific reasons.
