Computer registry problems can strike an unsuspecting user's computer at any given time. A variety of problems can constitute a problem within the registry. The different types of computer registry problems include entries that are invalid, obsolete, corrupt, damaged or redundant. Erratic computer behavior, slow startup times and slow shutdown times are all possible results of computer registry problems.
When a user installs new software, information about it is stored directly in the registry. When the program is uninstalled, however, the information in the registry might not be deleted. After a while, this clutters and bloats the registry, causing computer registry problems.
Leftover registry keys are the most common cause of computer registry problems, but they are far from the only reason for these problems. Perhaps the next common reason is malware, which is software that intends to bring harm to the computer, purposely corrupting the registry. In addition to erratic computer behavior, the malware might change executable files. In other words, trying to open one program will open up something else malicious while claiming that the original program is broken.
Fixing a corrupted registry is typically limited to using a registry cleaner program. Before deciding upon a registry cleaner, it is important for the computer user to keep a few things in mind. Choosing the wrong registry cleaner can have dire effects on the computer, and it could leave it in an even worse state than before.
One of the most important things that the computer user should keep in mind is to use a program compatible with the version of the computer's operating system. Even versions of the same operating system can react differently if an incompatible registry cleaner is used. Any reputable downloading website will list the recommended operating system for a program..
Finally, a cleaner for computer registry problems should come from a reputable downloading website. The same people who want to infect computers with malware are also known to create fake registry programs in hopes of catching those who don't know any better. A user should always take caution and never download anything from an unknown website.
