If you are not sure what operating system (OS) a computer is running, use information here to find it.  It's important to know the OS and version if the computer has problems and you need to contact technical support, or are looking to install software or set it up with other technical resources.

Most computers at CUIMC use either Windows (owned by Microsoft) or Macintosh (owned by Apple) operating systems. The operating system, also referred to as the "OS", runs basic functions on the computer. As time passes the OS vendor releases new versions so they remain compatible with newer computer models, hardware and software programs.

Windows or Macintosh?

To tell whether your computer is Windows or Macintosh, look for one of these icons:

Computers using a Windows operating system have a Windows flag/Start icon in the lower left corner of the screen.

Computers using a Macintosh operating system have an Apple icon in the upper left corner of the computer screen.

The initial screen you see after turning on and/or logging in to the computer will also tell you if it is Windows or Macintosh:

 

Each operating system also has a version, indicating how recently it was released.  For help looking up the version see our instructions for Windows or Macintosh.
