    I got a 404 on that link but i guess what you are after is how to use RegDeleteKey

    LONG RegDeleteKey(HKEY , LPCTSTR);

    the first parameter is the main key. Whatever you want in the registry will be a subkey of one of these....

    HKEY_CLASSES_ROOT
    HKEY_LOCAL_MACHINE
    HKEY_USERS
    HKEY_CURRENT_USER
    HKEY_CURRENT_CONFIG
    HKEY_DYN_DATA
    HKEY_PERFORMANCE_DATA

    the second parameter is a pointer to a generic string that identifies the particular subkey of the first parameter that you wish to delete. If you specify a subkey that itself has subkeys then they will be deleted too. If the function succeeds it returns 0. A non zero return value indicates error which you can find out about using GetLastError()

    for instance to cause major registry trouble....
    TCHAR myregkey[] =TEXT("System\\CurrentControlSet");
    LONG mydelregret= RegDeleteKey(HKEY_CURRENT_CONFIG,myregkey);
    if (mydelregret) // time for GetLastError() to see what went wrong

    edit....

    was wrong.... only deletes subkeys on 9x. doesn't on nt,2k or xp
    also forgot TEXT macro in code sample.

    I am so dumb. I misclicked when I copied the link. I meant to give this one. It is a different function and it deletes a value instead of a key(definately not what I wanted to do). In the explanation, it says I have to include the value to be deleted but I was wondering if I had to include the full path name. Thanks for your help.
