Know exact usage Time on ur PC

How much time is passed...?
Well it happens always , we sit on computer and after sometime when we look at the clock we see that Oh, my god !!!!! so much time has passed. but we don't know exactly how much.

Just copy the below lines in notepad:

@echo.
@systeminfo | @find "System Up Time:"
@echo.
@pause


Now save this file with the name uptime.bat on your desktop or somewhere u like.

Now whenever you want to check how much time has passed after you last started your computer , just double click on the file uptime.bat and you will get the exact time for how long your computer is up.
