Your welcome. No one ever wants to debate me on this, but if $vars in strings are evil, than %vars%'s in strings are equally evil.



We did have a rambling debate on this, but I can't find it. I'd agree that "no vars" should include anything that might be expanded, including macros and environment strings.

I did turn up a quote from Ruud stating that he intended to have a NoMacrosInStrings.

should HKCU and HKLM also be excluded cuz they too are macros of sorts.



Not really. They don't get expanded at all - HKCU is just HKCU regardless of how or where you use it. The only thing that is special about it is that if it is at the start of a string passed to a registry function it is recognised by the function as a shorthand or alias. The string that the function receives however remains unchanged.
