If you're not among the high tech crowd, you may need to use some tough love on your computer.  Stop letting it kick you around. 

You know when you pop in that thumb drive and it starts copying all of the pictures, when all you wanted was a contract? 

You know when the program asks you, shall I ALWAYS open all files of this type like this FOREVER? 

You know when suddenly all of your familiar little wmv icons turned to   quick time and you don't know how?

When you saved something and it went somewhere and now you can't find it? 

Well, all of these applications have PREFERENCES, and naturally they're set to promote themselves as much as they can.  Let me open all your files, let me access the internet, let me automatically copy all files from anything you stick into your computer!  Like a good parent, you need to take a firm line here.  Go into those application preferences and set them straight..... tell them what you want them to do, where the default folder for saving or downloading is,  and whether you want them to do anything automatically.  You'll find that unlike children, you only have to tell them once.
