Errors in the registry are annoying. They not only cause computer sluggishness but worse are the headaches they bring to the user. Like what analgesics can do to headaches, free registry repair from the internet are fast relievers for computer problems.

Fixing the Windows registry has a lot of benefits. Registry repair tools free-up the registry from congestion. Junk files could be there from program installation and uninstallation made. Unnecessary files come along with installed software that won’t go away even after removing them. Data acquired from the internet unknowingly crowd the registry when you browse on-line.

ActiveX issues may also reside in the registry. The activeX controls are possibly corrupted by malware that invade the registry. Such computer contaminants are also target objects of the registry repair tools.

Malware is the general term used for infections such as viruses, trojans, worms, spyware, deceiving adware and other malicious programs that disrupt and/or deny operation of applications and obtain entry to resources of the system to develop information that cause lost privacy. In short, they are hostile forces that corrupt the registry. Many times they slip past the installed security protection (anti-virus programs) that has no updated malware database. Software is considered malware when its creator has no other intent but to interfere and create disorder in the computer system. A potent free registry repair can effectively find and destroy them.

Invalid file extensions are another registry problem fixed by repair tools. Just like the activeX controls, file extensions become invalid when damaged by malware to the extent that the Operation System can no longer recognize them. File extensions are filename extensions accessed by the OS through the command entered by the user. These file extensions are program-specific with uppercase or lowercase letters following a dot in their filenames.
