Registry Editor

The Main Window

This will be mostly self-explanatory to experienced computer maintainers. If this is all new to you, be very cautious that you do not make dangerous changes to your Registry - see the Welcome Page. Here are some brief details.

ViewsThe HivesKey ValuesMulti-Display Area


A more sophisticated systems of Views was introduced with Version 2 of RegCOPA.

A Windows option is available From the Views menu, to display or hide the panes individually, and the Keys and Values panes have small icons at their top right:

Values pane only. Maximise this pane. It will then occupy the space previously used by the Multi-Display Area , and if the Keys pane is closed or hidden, that area too.
Values pane only. Normalise - return pane to its usual form from being maximised (above).
Hide this pane. It can be temporarily shown again from the Views Windows menu, or by clicking on the orange label that will appear. Moving the mouse outside the pane leads to its being hidden again.
Unhide this pane - it will return to its usual permanently-displayed state.
Close this pane completely. It can be restored from the Views Windows menu.

The Hives

These are the five major 'containers' for the data, divided into functional units. The files containing them are not directly user-accessible, except through a suitable Registry Editor like RegCOPA.

Each contains a hierarchy of keys and sub-keys, which can be opened by either double-clicking or clicking on the little + to the left. Right-clicking displays a context menu.

Contains information about the file system such as file associations (which software should be used to handle with file types).

Contains information related to the current logged-in user, mostly copied from other parts of the registry: this is a dynamic area and changes to it will usually be changed again by user actions, or the logging out of the user.

The basic information about hardware an software on the machine. Values from here may be copied to other parts of the registry for actual use.

Information about the users configured to use the machine, such as names and individual configuration settings for the machine.

Information about the current configuration of the computer, which may have been obtained from other parts of the registry, or may be other temporarily held information.

There is also another hive, not normally displayed in registry editors:

Key Value

When a key or subkey is selected in the left-hand pane, the values stored in that key is displayed here. Each key may have any number of values under different names. For instance if you use MailCOPA email client, there is a key called Paths that holds values showing the paths to

Keys can store data in three fields:

Name - Just a name given to this entry

Type - the data format for the information

Data - the actual contents of this information

Comment - A text field used for noting, for instance, the meaning or use of this key. (eg "Fred put this here on 1st March just to see what happens" !). This information is not stored in the registry itself, but forms one of RegCOPA's Registry Extensions.
