How to find the activities that occurred on my computer

There is a tool called LastActivityView by Nirsoft. It's pretty nice tool I have used it many times. Once, I used it to trace activities on my laptop because one of my office friend from HR department borrowed my laptop in emergency need. After returning my laptop,  I was little curious to see what files and documents opened on my laptop. This will help you with following:-
1) It will show you what files and folder were opened or viewed with windows explorer or other software.
2) It will show you information about software installation and un-installation.
3) It shows systems started time as well as shutdown time.
