RegDeleteValue function
Removes a named value from the specified registry key. Note that value names are not case sensitive.
Syntax
LONG WINAPI RegDeleteValue( __in HKEY hKey, __in_opt LPCTSTR lpValueName );
Parameters
- hKey [in]
-
A handle to an open registry key. The key must have been opened with the KEY_SET_VALUE access right. For more information, see Registry Key Security and Access Rights.
This handle is returned by the RegCreateKeyEx, RegCreateKeyTransacted, RegOpenKeyEx, or RegOpenKeyTransacted function. It can also be one of the following predefined keys:
HKEY_CLASSES_ROOT HKEY_CURRENT_CONFIG HKEY_CURRENT_USER HKEY_LOCAL_MACHINE HKEY_USERS
- lpValueName [in, optional]
-
The registry value to be removed. If this parameter is NULL or an empty string, the value set by the RegSetValue function is removed.
For more information, see Registry Element Size Limits.
Return value
If the function succeeds, the return value is ERROR_SUCCESS.
If the 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.

When lpValueName points to a location within a memory that has been allocated via GlobalAlloc(GMEM_FIXED...) you get this error.
The solution is to copy the String to a local buffer on the stack.
