Okay, how do I check to see what operating system it has?

And how do I check the printer/scanner settings in the control panel?

Thanks

Also, I have just updated to Internet Explorer 7 on my Windows XP HP pavillion. Now I don't have the favorite places on the left side of my screen.
I have to click on the star on the left side and it brings up the favorites.

Is there anything I can do to keep the favorites on the left side of the screen and have them there all the time?

Thanks.
Melody
