Would you like to see when your machine was running? With this simple application you are able to do so. There is not much more to say about that other than it needs at least Windows Vista to run properly, so give it a try and enjoy beautiful data.
Why does it not show the entire history? Windows clears the internal event journal after a while, which removes the necessary uptime information. Apologies for this inconvenience. Why does the application not run on my computer? If the application is being executed on a computer with at least Windows Vista, please feel free to submit the issue through the bug tracker.
