When the install is complete click the Start button, All Programs, then find and click StopWatch in the list of programs
See 'Set It Up' in the User Guide for how to set up your StopWatch features.
If you're more of a visual learner than a reader, you can get a lot of details from watching the tutorials on 'How to use it', and 'Cool things you can do with it'. Just click the Demos button on the main page of www.stopwatchprivacy.com. We hate those really fast demos at other peoples sites, so ours presume you like relaxed 'Joy of Painting' style tutorials where you actually know what to do when you're done watching. That's our goal, anyway
