RegAlyzer 2, currently available as a release candidate, will support a multi-tabbed interface, value interpretations, constant names for values, and snapshots of hives to track changes. RegAlyzer includes a database of some common registry locations including details that help interpret registry values, by providing constant names and descriptive texts. RegAlyzer allows you to track changes to your registry by comparing its current state against snapshots you have made. RegAlyzer 2 brings a new bookmark manager that offers hierarchical storage for bookmarks. RegAlyzer locates inactive hives on other drives and allows you to use the registry inside.
