Quick start

This page gives you the shortest reliable path to your first change in O&O RegEditor.

The main O&O RegEditor window

Figure: The main window – key tree on the left, value list on the right.

Before you start​

Changing the registry can affect the stability of Windows and installed programs. Before you edit anything important:

  1. Make a current backup of your data.
  2. Export the key you are about to change so you can restore it later. See Export.

Make your first change​

  1. Open O&O RegEditor.
  2. In the key tree on the left, expand a main key (for example HKEY_CURRENT_USER) and navigate to the key you want to edit. Alternatively, type or paste a path into the address bar and press Enter.
  3. Select a key. Its values appear in the value list on the right.
  4. To change a value, double-click it – or select it and press Enter – to open the value editor.
  5. Enter the new data and confirm with OK.
  6. To add something new, right-click a key and choose New to create a subkey or a value of the type you need.

The change is written to the registry immediately.
