Chapter 35. The Registry > Advanced Registry Editing with Regedt32

Advanced Registry Editing with Regedt32

Windows comes with an alternative Registry Editor named Regedt32, which was the version shipped with Windows 95 and NT version 3. The user interface for Regedt32 is more awkward than Regedit's because it doesn't have a left Explorer pane. Instead, each of the top-level keys is opened in a separate window (see Figure 35.12). Other than the display differences and slightly different labeling of the menu choices, the functions in Regedt32 are almost identical to Regedit. However, Regedt32 has three features that Regedit doesn't:

  • You can insert REG_MULTI_SZ and REG_EXPAND_SZ values. These two data types are not available in Regedit, and they're needed for certain seldom-seen Registry keys.

  • You can attach hives (Registry data files) to the Registry. For example, normally the HKEY_CURRENT_USER hive for a given user is joined to the Registry only while the user is logged in. Regedt32 lets you attach another user's hive to the Registry so that his or her data can be modified while he or she is not logged in.

  • You can modify the security attributes of Registry keys and values with Regedt32. Just like files and folders, Registry keys and values have a complete set of Access Control attributes that determine who has rights to read, write, and modify the Registry. Regedt32 lets you examine and modify Registry access rights and auditing.

    Figure 35.12. Regedt32 uses an old-style user interface but has some advanced features that Regedit lacks. Each primary key in the Registry is displayed in a separate window.
