Registry Finder is a free tool for searching and editing the Windows Registry.
The program opens with a REGEDIT-type view. Your Registry is represented in a tree on the left, with individual items on the right, and you can double or right-click to edit them or add something new.
There are some interesting extras. Registry Finder has a web-like Address Bar at the top, providing another way to navigate your system. And Back and Forward buttons on the toolbar make it easy to review the keys you've browsed.
The History pane is another useful addition. Delete something and it appears here. If you've decided you've made a mistake, clicking Edit > Undo brings it back.
The "Find" feature is particularly strong. You're able to search the entire Registry, or just a particular key; there's an option to run case-sensitive searches; and unlike REGEDIT, the program doesn't just return its matches one-by-one. Instead they're all displayed at once, and in a separate tab, so you can easily browse the list and switch back to some other Registry view as required.
Version 2.21.1 (Changelog):
Fixed crash when specific string value is encountered. (Introduced in 2.21)
Registry Finder has some quirks and omissions, and doesn't always work as you'd expect. These issues are relatively small, though, and on balance it's becoming a very capable Registry editor.
