    interesting, but why was it

    Program Files and Program Files x86

    instead of

    Program Files and Program Files x64?

    Because x64 was set to become the standard so it got the basic naming.

    Well it's actually not true that all programs under "Programs Files" are 64-bit, on a 64-bit Windows. The "WindowsApps" folder have all apps downloaded from Windows Store, including those of 32-bits and platform-neutral apps.

    I get the point about the x86 and the default, but in older Windows version, you did not had a "Program Files" and "Program Files 16-bit" folder?
