This free time tracking tool displays the times your computer has been active during the last 3 weeks without any setup. The software does not need to run in the background, as Windows OS tracks login and logoff times (working hours) by default, and the program analyses it. PC On/Off Time is Freeware and displays the working time graphically. It does not require runtimes, installation, writing to the registry, or modifying files outside of its own directories, and is not adware.
