Return Values

ERROR_SUCCESS indicates success. A nonzero error code defined in Winerror.h indicates failure. To get a generic description of the error, call FormatMessage with the FORMAT_MESSAGE_FROM_SYSTEM flag set.


If the function succeeds, CeRegDeleteKey removes the specified key from the registry. The entire key, including all of its values, is removed. An application cannot call CeRegDeleteKey for a key that an application currently has open.

To open the key, use the CeRegCreateKeyEx or CeRegOpenKeyEx function.
