X-Win32: Windows Download for Personally Owned Computers

A proprietary implementation of the X Window System for Windows computers. X-Win32 allows remote display of UNIX/Linux windows on Windows machines as a normal window.

Note: This software can be downloaded multiple times and does not limit the number of installations.

About X-Win32

X-Win32 is an X terminal application which allows PC users to connect their Windows-based computer to a Linux or UNIX server, such as ubunix.buffalo.edu. It allows X application programs located on other computers on the local area network to connect to your computer, and will use your computer to display the results.


X-Win32 is available to UB Students, Faculty, and Staff in both the 2014 and 2018 versions.

Installing X-Win32

You must have an active account on a system running Unix/Linux to use X-Win32.

  • Enter The University at Buffalo as the Organization.
  • Choose Complete install.
  • Make sure that Install UB Customizations is selected at the end of the install process before clicking Customize.
  • Launch X-Win32 immediately after installing. You will receive an error and then be prompted for a product key. The key will have opened in a window on your computer; Copy it and paste it into the key field.
