Details
Ver outputs the version of the currently running prompt on the screen. Particularly in MS-DOS, this version depends on the contents of IO.SYS and MSDOS.SYS, and different versions may be displayed depending on the boot disk used.
[MS-DOS, Windows 95/98/Me] If you want to provide compatibility information from a different version for DOS applications, you can use Setver.
[Windows 10 or later] The version is outputted, including the revision number. This allows determining which features of Windows are installed.
