open key or any of the following predefined reserved handle values:
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
lpValueName
Points to a
null-terminated string that names the value to remove. If this parameter is
NULL or points to an empty string, the value set by the RegSetValue
function is removed.
Return Values

function succeeds, the return value is ERROR_SUCCESS.

function fails, the return value is a nonzero error code defined in WINERROR.H.
You can use the FormatMessage
function with the FORMAT_MESSAGE_FROM_SYSTEM flag to get a generic description
of the error.

KEY_SET_VALUE access (KEY_WRITE access includes KEY_SET_VALUE access).
