From time to time, you may run into a program that will run only on certain versions of Windows.  If you have never had a reason to worry about what you are running, it may not be immediately obvious which one you are running.

Most of the computers in the district are running Windows NT Workstation.  Some older computers and most laptops, however, have different operating systems installed on them.  The easiest way to tell what family of the Microsoft Windows® operating system is installed on your computer is to click on Start.  The name of the version of  Windows which you are running is displayed along the left edge of the Start menu:
 

In this case, Windows NT Workstation is being used.  The different versions you may see here are: Windows 95 Windows 98 Windows NT Workstation Windows Me Millennium Edition Windows 2000 Windows XP (Future versions of Windows) Most programs (though not all) will run on all of these if they run on any of them.  NT, 2000 and XP are most likely to have trouble with software that runs o n other versions of Windows.  However, they are also much more stable and secure than the other versions of Windows. Windows version 3.1 is an older version of Windows that is on a few of the oldest computers still in the district.  (Computers that are five or more years old.)  Windows v3.1 has a completely different look to it and does NOT have a Start button.  Windows v3.1 can NOT run any programs written for the other versions of Windows.
