What Is a Tune-Up Utility?Ī PC tune-up utility is an application that digs deep into your computer and fixes trouble areas. Instead, you can get often that fresh-out-the-box performance for tens of dollars-instead hundreds or even thousands-thanks to a relatively inexpensive tool: the PC tune-up utility. But that's a drastic solution, and one that's frequently unnecessary. When our machines become so impaired through use and neglect that we can no longer use Microsoft Word or play PC games with the same speed and efficiency to which we have become accustomed, we often ponder buying new computers. It doesn't matter how diligent you are, or what sort of productivity software you use to get the most out of your time if end up sitting around and waiting for your computer to catch up to you.

Toolbars and other nasty plug-ins can precipitously slow our browsers to a crawl. Outdated drivers cease to work correctly. Eventually, our full hard drives choke the OS as it tries to run. Programs build up enormous caches behind the scenes that we don't even know about. Their hard drives fill up with forgotten files we've abandoned in folders whose existence we've forgotten.

The operating system gets gunked up as apps are added and incompletely deleted, leaving behind drivers and all sorts of other system detritus. All computers eventually lose that day-one luster, becoming lethargic, unresponsive, and even unreliable.
