Registry Explorer provides improved features over the built-in Windows Regedit.exe. If you work within the registry and have always wanted a little more functionality, this little Open Source app may be the ticket to help make it a more efficient experience.

Replacement for the Windows built-in Regedit.exe tool. Improvements over that tool include:

Show real Registry (not just the standard one)
Sort list view by any column
Key icons for hives, inaccessible keys, and links
Key details: last write time and number of keys/values
Displays MUI and REG_EXPAND_SZ expanded values
Full search (Find All / Ctrl+Shift+F)
Enhanced hex editor for binary values
Undo/redo
Copy/paste of keys/values
Optionally replace RegEdit
more to come!
