Hi Stefan,

Apparantly I got it all wrong from the start. (MSDN confused me....
again). The text on MSDN for SHDeleteKeyW says it also deletes the
key, the text for RegDeleteTree misses that part which led me to
believe there was a difference.

Our (your) tests show however that RegDeleteTree also deletes the key itself.

You're patch is correct in that respect and doesn't the last part of
the code remove the key itself ?:

RegCloseKey(hSubKey);
        if (!dwRet)
            dwRet = RegDeleteKeyW(hKey, lpszSubKey);

I will adjust the wiki page.

Cheers,

Paul.
