RegAlyzer is a tool to browse and change the registry. I wrote it because of a few features I missed in the original regedit tool.

• 1.4 (December 13th, 2005) Fixed drive-not-available bug, fixed auto-refresh problems, adjusted version number to fit in the line.
• 1.2 (September 19th, 2005) Fixed new value bug, fixed value editing bug, fixed broken remote connection bug.
• 1.1.5 rel 3 (July 8th, 2005) Maintenance release including more translations.
• 1.1.5 rel 2 (June 2005) Maintenance release including more translations.
• 1.1 (March 4th, 2005) small fixes, WinPE/BartPE compability (automated mounting of registry on other drives), automated update if current key changed.
• 1.0e (September, 25th 2003) improved remote connections, added drag'n'drop, improved search, small fixes.
• 1.0d (September 5th, 2003) improved search, added support for short rootkey names.
• 1.0c (August 12th, 2003) search speed-up, window size/position saved, bookmark management, REG_RESOURCE_REQUIREMENTS_LIST display, improved import and export of special registry keys.
• 1.0b (July 29th, 2003) fixed a few bugs.

A short list of the pros of RegAlyzer:

• 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)
• Display of .reg file contents without importing it
• Support of version 5 files (Unicode) even with Windows 95/NT
• Low-level display of security settings with option to export it

But there are a few not-yet completed features as well:

• Complete Unicode support
• Display and import support for some system stuff (REG_LINK, REG_RESOURCE_DESCRIPTOR, etc.)
• Changing security settings
• Remote connection doesn't ask login yet
• Changing opened .reg file
• Editing binary data
• Working (add/delete/etc.) in remote registry

RegAlyzer is still in development, as you can see from the 'missing' list above. So expect a few improvements in the near future!
