I know nowadays it's very commont to pick on Microsoft, but they've delivered quality products, and even if you don't like Windows (I don't love it) it's a pretty decent operating system with lots of backwards compatibility. Excel is great. Visual Studio is great
Visual Studio didn't hold up to its competitors in the past (Delphi) and doesn't hold up to its competition now either (JetBrains)
it's another fine example of MS software being mediocre at best
