A Tale of Two Regeds: Registry editors
Tech support tells me to type ‘regedt32′ as opposed to ‘regedit’ to access the registry from the command line (Start > Run). I question the use of ‘regedt32,’ but he says to do it anyway. Whenever I use the registry editor, I recall this incident and never look up the tale of the two regs… until now.
Regedt32.exe is an alternative registry editor available with Windows NT/2000 with features of its own. Regedt32.exe does not support importing and exporting registration entries (.reg) files. Regedit has limitations of its own as quoted here:
“You cannot set the security for registry keys. You cannot view, edit, or search the value data types <>REG_EXPAND_SZ and <>REG_MULTI_SZ. If you try to view a <>REG_EXPAND_SZ value, Regedit.exe displays it as a binary data type. If you try to edit either of these data types, Regedit.exe saves it as <>REG_SZ, and the data type no longer performs its intended function. You cannot save or restore keys as hive files.”
Research indicates regedit has:
- a better search tool
- bookmarking of subkeys
- opens to last edited subtree, export and import capabilities
- all keys are visible from a window similar to Windows Explorer
Regedt32 (pre-WinXP) can:
- run in read-only mode
- allows you to edit values longer than 256 characters (who wants to do that???)
- displays subtrees in their own windows
- modify access permissions to subtrees, keys, and subkeys
