What Operating System Does My Computer Use?

Most computers used at CUMC 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:

Windows 7 Start Icon Windows 8 Flag Computers using a Windows operating system have a Windows flag/Start icon in the lower left corner of the screen. Apple IconComputers 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:
Windows 7 or Vista desktop with Start icon in lower left
