Хмм быть может так:
The RegCreateKeyEx function creates the specified key. If the key already exists in the registry, the function opens it.
LONG RegCreateKeyEx(
HKEY hKey, // handle of an open key
LPCTSTR lpszSubKey, // address of subkey name
DWORD dwReserved, // reserved
LPTSTR lpszClass, // address of class string
DWORD fdwOptions, // special options flag
REGSAM samDesired, // desired security access
LPSECURITY_ATTRIBUTES lpSecurityAttributes, // address of key security structure
PHKEY phkResult, // address of buffer for opened handle
LPDWORD lpdwDisposition // address of disposition value buffer
);
Parameters
hKey
Identifies a currently open key or any of the following predefined reserved handle values:
HKEY_CLASSES_ROOT
HKEY_CURRENT_USER
HKEY_LOCAL_MACHINE
HKEY_USERS
The key opened or created by the RegCreateKeyEx function is a subkey of the key identified by the hKey parameter.
lpszSubKey
Points to a null-terminated string specifying the name of a subkey that this function opens or creates. The subkey specified must be a subkey of the key identified by the hKey parameter. This subkey must not begin with the backslash character ('\'). This parameter cannot be NULL.
dwReserved
Reserved; must be zero.
lpszClass
Points to a null-terminated string that specifies the class (object type) of this key. This parameter is ignored if the key already exists.
fdwOptions
Specifies special options for the key. Currently, this parameter can be one of the following values:
Value Meaning
REG_OPTION_VOLATILE Windows 95: This value is ignored in Windows 95. That is, even if REG_OPTION_VOLATILE is specified, the RegCreateKeyEx function creates a nonvolatile key and returns ERROR_SUCCESS.Windows NT: This key is volatile; the information is stored in memory and is not preserved when the system is restarted. The RegSaveKey function does not save volatile keys.
REG_OPTION_NON_VOLATILE This key is not volatile; the information is stored in a file and is preserved when the system is restarted. The RegSaveKey function saves keys that are not volatile.
By default, keys are not volatile. This option is ignored if the key already exists.
The RegSaveKey function only saves nonvolatile keys. It does not save volatile keys.
samDesired
Specifies an access mask that specifies the desired security access for the new key. This parameter can be a combination of the following values:
Value Meaning
KEY_ALL_ACCESS Combination of KEY_QUERY_VALUE, KEY_ENUMERATE_SUB_KEYS, KEY_NOTIFY, KEY_CREATE_SUB_KEY, KEY_CREATE_LINK, and KEY_SET_VALUE access.
KEY_CREATE_LINK Permission to create a symbolic link.
KEY_CREATE_SUB_KEY Permission to create subkeys.
KEY_ENUMERATE_SUB_KEYS Permission to enumerate subkeys.
KEY_EXECUTE Permission for read access.
KEY_NOTIFY Permission for change notification.
KEY_QUERY_VALUE Permission to query subkey data.
KEY_READ Combination of KEY_QUERY_VALUE, KEY_ENUMERATE_SUB_KEYS, and KEY_NOTIFY access.
KEY_SET_VALUE Permission to set subkey data.
KEY_WRITE Combination of KEY_SET_VALUE and KEY_CREATE_SUB_KEY access.
lpSecurityAttributes
Points to a SECURITY_ATTRIBUTES structure that specifies the security attributes for the new key.
If this parameter is NULL, the key receives a default security descriptor. If the operating system does not support security, this parameter is ignored.
phkResult
Points to a variable that receives the handle of the opened or created key.
lpdwDisposition
Points to a variable that receives one of the following disposition values:
Value Meaning
REG_CREATED_NEW_KEY The key did not exist and was created.
REG_OPENED_EXISTING_KEY The key existed and was simply opened without being changed.
Return Value
If the function succeeds, the return value is ERROR_SUCCESS.
If the function fails, the return value is an error value.
Remarks
The key that the RegCreateKeyEx function creates has no values. An application can use the RegSetValue or RegSetValueEx function to set key values.
The key identified by the hKey parameter must have been opened with KEY_CREATE_SUB_KEY access. To open the key, use the RegCreateKeyEx or RegOpenKeyEx function.
An application cannot create a key under HKEY_USERS or HKEY_MACHINE.
An application can use RegCreateKeyEx to temporarily lock a portion of the registry. When the locking process creates a new key, it receives the disposition value REG_CREATED_NEW_KEY, indicating that it "owns" the lock. Another process attempting to create the same key receives the disposition value REG_OPENED_EXISTING_KEY, indicating that another process already owns the lock.

В MFC я не копенгаген. По аналогии с edit control попробуй ES_MULTILINE в Create и/или "\r\n"
