SUMMARY

This article describes how to determine the version of the Interix subsystem that is in use.

MORE INFORMATION

There are two ways to determine the version of the Interix subsystem:
  • Note the file versions of the following files in the %SystemRoot%\System32 folder:
    • Psxss.exe
    • Psxdll.dll
    • Psxrun.exe
    • Posix.exe

    The file versions correspond to the subsystem version.

  • In Interix 2.2.4 with Service Pack 1, you can run the Fileinfo utility from an Interix command window. This utility displays the subsystem version information.
