Lexun RegScrubXP is a very popular utility designed to delete unnecessary information from the System Registry of Windows XP & 2000 operating systems. This ‘junk’ is often left behind when programs are uninstalled and the information is not needed anymore. Programmers sometimes mistakenly load junk into the Registry as well. Using RegScrub to clean out the junk results in a smaller, faster Registry. Your operating system accesses the Registry a lot, so keeping it clean is a good idea! RegScrubXP also helps you tweak your Registry to provide a more pleasant computer experience.
