I missed the now-deleted message you replied to, but if it was objecting to the term "Spy", that may be partly my fault. I wrote a Windows program called Spy back in 1987 for a BYTE Magazine article. Spy++ was inspired by this program, and true to its name, Spy++ was much better!

Here's some old-school Windows programming, along with great ads for the hot computer products of the day:

Oh wow, you weren't kidding when you said old-school! Some of the adverts in there are great too :)
