I notice that Windows XP Event Viewer show a list of typical actions under System logs every time I start or shutdown Windows, and I can tell when my day starts and ends.
Is there anyways I can record the time every time I lock my screen and every time I re-login? There maybe a way to fool System Event Logger into submission, but a free third party tool would be good too if not.
I thought this post had some interesting thoughts about this subject. You might want to take a look at it.
