How Do I Fix My Registry?

The Windows Registry is a massive database representing your PC's unique configuration. Depending on who you ask, the massive code repository is either an invaluable reference tool for all of the software on your computer, or a garbage dump that stinks up everything around it. The truth probably lies somewhere between those two extremes.

In the earlier section, "Why Is My PC Acting Up?," I noted that you can back up the Registry using the free ERUNT utility. Once you have a backup in place, you're ready to clear out some Registry refuse.

Clean house: My favorite utility for Registry cleaning is ChemTable's Reg Organizer; see FIGURE 3). The tool helps you examine all of your startup applications, file types, and other specific trouble spots. The program also has a fabulous search-and-replace function. You can either perform an automatic cleanup if you're not in a hands-on mood, or scrub the Registry manually. The bad news? The application is $30. A free alternative is ToniArts' EasyCleaner, which does a reasonable job.
