A Tale of Two Registry Editors
When I contacted tech support, I was instructed to type 'regedt32' instead of the more familiar 'regedit' to access the registry via the command line (Start > Run). This raised questions in my mind, but I followed the advice. It became a memorable episode, prompting me to finally explore the story behind these two registry editors.
Understanding Regedt32 and Regedit
Regedt32.exe, an alternative registry editor, was available with Windows NT/2000. Unlike Regedit, Regedt32.exe is limited in handling .reg files since it doesn't support importing and exporting registration entries. Regedit also has its limitations:
- It doesn't allow setting security for registry keys.
- Viewing, editing, or searching certain data types like REG_EXPAND_SZ and REG_MULTI_SZ is not supported.
- Editing these data types alters them to REG_SZ, which prevents their proper function.
- Saving or restoring keys as hive files isn't possible.
Regedit's Features
Despite its limitations, Regedit offers several useful features:
- A robust search tool.
- Ability to bookmark subkeys.
- Resumes from the last edited subtree and supports export/import capabilities.
- Displays keys in a user-friendly, Windows Explorer-like interface.
Regedt32's Capabilities
On the other hand, Regedt32 (pre-WinXP) includes:
- A read-only mode.
- Ability to edit values longer than 256 characters.
- Displays subtrees in separate windows.
- Allows modification of access permissions for subtrees, keys, and subkeys.
The Evolution in Windows XP and Server 2003
With the arrival of Windows XP and Server 2003, these two editors merged into a new version of Regedit, incorporating features from both. Typing either 'regedit' or 'regedt32' leads to the same destination. Notably, the 'permissions' feature?"previously exclusive to Regedt32?"became accessible in Regedit.
In essence, 'regedt32' functions as a small program to run Regedit. Therefore, whichever command you choose, the outcome remains the same. Personally, I find 'regedit' easier to remember.
The tech support representative likely asked me to use 'regedt32' to check permissions settings. However, it was outdated advice for Windows XP users. While tech support should have known this, it's a reminder of how quickly technology evolves.
Further Resources
For those curious about the differences between these registry editors, Microsoft offers a knowledge base article. Additionally, the Windows IT Library has an older feature comparison chart from 2000. For alternative registry editors, there are various options to explore. For tweaks and tips, WinGuides' Registry Guide for Windows is a valuable resource.
By understanding the history and functionality of these tools, users can better navigate and utilize the registry editing process in Windows.
