Single-click was implemented possibly by 2k but definitely by XP. Think it had to do with IE—yes, details below.

  You could single-click to open files in Windows 98 already. You could also hover your mouse pointer on a file icon and it would become selected.

    It was the Internet Explorer shell integration that brought us this feature. The idea was to blend the desktop and web user interfaces. If you installed IE4 on Windows 95, you'd get that option there too.

      Yes, it was called Active Desktop if memory serves.
