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

whilst modern Windows is malware
