PostPoints tip: Beware of quick Registry fixes

The Windows Registry--a vast database of system settings that governs both Microsoft's operating system and programs running on it--is at the root of many common Windows ailments. It can get clogged with references to old programs, corrupted entries can lead to mysterious crashes, and the cryptic, jargon-soaked entries that fill up the Registry are themselves largely unreadable to non-programmers. So it can be tempting to download a free program that claims to fix those Registry issues for free. Problem is, not all of these repair tools work as advertised, some require a fair amount of computing knowledge, and a Registry fix gone wrong can leave you with a seriously damaged Windows system. So unless you see a Registry repair program recommended by a known and trusted source, don't even think about installing it. Meanwhile, keep this rule in mind: The simplest way to keep your PC running well is to be choosy about adding software to it in the first place.
