CHANGING WINDOWS FROM A TORTOISE TO A HARE
Windows can be as slow as a tortoise. You try all the tricks in the book, but your computer still crawls along. During some computing sessions, things sort of limp along, but in others, you can barely get the mouse to move.
Defragmenting the hard drive, uninstalling programs you don't use, closing applications you aren't using - all seem to have at least a temporary effect, but sooner or later, your PC just goes back to its old, slow ways.
It turns out that there are a bunch of things in Windows itself - especially in Windows XP, now the dominant version of the operating system in the marketplace - that actually hamper performance.
But it also turns out there's a quick fix that'll change your PC from a tortoise to a hare.
