How to Set a Timer on the Computer
- 1). Download and utilize TimeLeft, which enables a countdown timer on your desktop that can be set to perform a variety of tasks, such as shutting down your computer, disabling an application or opening a particular document.
- 2). Consider the PC Timer, a countdown program which can be minimized at will to the system tray. This program can be customized to play a particular song, alarm file or message when the timer expires.
- 3). Utilize NoFrillsTimer, which is the smallest application timer of the three, useful if hard drive space is a concern. This program can display warnings onscreen when time expires, but cannot execute commands like the other two programs.
