RegAlyzer is a tool to browse and change the registry. It was created because of a few features we missed in the original regedit tool, from support for exotic value types over background and regular expression search to better bookmarks, displaying .reg files in the accustomed style and a history view.

A short list of the pros of RegAlyzer:

* Undo and Redo logs in .reg format
* Improved search function (results list)
* Hierarchical bookmark support
* Jump to key by command line parameter
* Jump to key by typing/copying it into dialog (instead of browsing)
* DWord editing with parallel hex/decimal/binary display
* Support of QWord (64 bit integer)

Search and clean your registry. Search for any item inside your registry, export/delete the results, open them in the registry. Includes a powerful registry cleaner and can display various information like startup entries, several histories.
