RegScrubVistaXP is a registry cleaner/viewer freeware program written by Nick McCamy.
RegScrubVistaXP was designed not only for casual users to safely repair the registry, but allows advanced users and IT professionals to view customized defined sections of the registry on a regular basis. This can significantly assist in deleting unwanted entries as a result of un-clean uninstalls and programmer errors, or malicious attempts to destroy the registry.
When problem results are displayed, you can even have Windows Explorer browse right to the folder of the missing file reference, and have RegEdit browse right to the referenced key. This saves significant time in verifying problems that RegScrubVistaXP detects.
Every repair that RegScrubVistaXP performs can be completely and quickly restored.
RegScrubVistaXP is free.
