Most desktop computers and laptops run the Windows® operating system, this can be determined by looking at the corners of your screen and finding the Start icon and taskbar. If you are unable to find the icon and taskbar, move your mouse pointer along the edges of your screen to display it, as it may be hidden.
While the Windows taskbar is usually found along the bottom edge of the screen, it can be docked to any side including the top.

Other Operating Systems
Basic phones, MP3 players, and similar consumer devices also rely on an operating system to function. This is often referred to as Firmware because as its name, it is firmer than software and cannot be altered as such. Firmware is usually locked down by the device manufacturer and can only be updated via a process called flashing.
Knowing the exact operating system in use by such devices is not required, but being aware of the brand and model number is essential.
