Upon the first run of this registry cleaner it scanned an XP system with SP2 and found 401 registry errors. The overview tab of the tool shows a "registry health" rating, in the case of this system it was "low".
The registry scan results are broken down into three separate groups: System Related Errors, which are errors affecting all users on the same system, User Related Errors, which address issues with a specific Windows account, and Third Party Related Errors, or issues affecting other programs.
This tool runs fast and performs a thorough scan of your Windows registry, though no other optimization tools are included, this tool specifically targets the registry and nothing else.
