PC On/Off Time graphically shows the working time on your computer of the last 3 weeks without logging your computer before. PC On/Off Time works with Windows Vista, XP, 2000. The software doesn't record activities, doesn't require runtimes, doesn't require installation, doesn't write to the registry, doesn't modify files outside of its own directories, isn't adware. You get an extensive evaluation of your working times and projects with the professional time tracking software Visual TimeAnalyzer at www.neuber.com/timeanalyzer - independent of your Windows version. On multiple request there are a Pro version ($9) and a Net version ($39) now available. These versions have a time unlimited chart of working time, a month overview instead of 3 weeks overview, an automatic backup that restores deleted events, a correct daylight time and comes without nag screens.
