I want to know when the computer turned on, how long it is used and when it is turned off. All must be shown in chart, so that i can easily view those details. I had one software to do this. But now i lost it and also forgot that software's name. Can anyone recommend me a good software for me?

I don't want any logging software that runs in background and reports the system usage. I want a software that tells the history when it is run even in new host system.

You could check the Windows Event Log and find out when key services start up and shut down.
