Actually a lot. It is terribly slow, it lacks intuitive and convenient search options and it doesn't find all the files you are looking for.

Have you ever had the experience of searching for that special file containing some particular phrase, a file you were absolutely sure about it was on your system, but Windows did not find it? That's likely because the Windows built-in search utility doesn't search in files with unknown extensions.
