Don't bother using this product, especially if you're running Windows Vista. I had this product on a previous computer with XP and for the most part it worked fine, although it slowed down the computer. The 2006 version was better for XP. As for using it on Vista, don't try unless you know anything about computers and safe modes and what to do when the computer errors and crashes. Because that's what it did to my computer about 4 times over until I finally managed to get it to start up in safe mode so I could uninstall it. What a nightmare.
