I installed this disservice pack on my newer HP desktop, and with the exception of slowing browser load times down, I like it. The popup blocker is a plus, but the thing I like most about it, is the startup process. It is basically the exact same thing as "Hibernating" for a laptop, but the PC is COMPLETLEY TURNED OFF. So when you hit the power button, the desktop is displayed in seconds. I find this the most compelling reason to download it. I want to know, though, is this new form of startup for every computer that runs XP? Or, is it some sort of newer technology in the HP that "Allows" it? The reason I ask is because I have an older PIII 800MHz laptop that I would like to have this feature on, sicne this laptop takes almost 4 minutes to start up. Any thoughts?
