Appearance
O&O RegEditor has a modern interface with dark-mode and High-DPI support.
Dark Mode
Choose the theme under View > Appearance:
Figure: The Appearance submenu.
| Option | Effect |
|---|---|
| Follow Windows | Uses whatever light or dark setting Windows is configured for, and follows it when it changes. |
| Light | Always uses the light theme. |
| Dark | Always uses the dark theme. |
The theme switches immediately; you do not need to restart the program.

Full dark-mode support requires Windows 10 version 1809 or later. On earlier versions the light theme is used.
High-DPI Display Support
The interface is High-DPI aware. Icons and toolbars are provided in several sizes and are shown crisply on high-resolution displays, so the program stays sharp on modern monitors and at higher scaling settings.
Window Title
The window title shows an abbreviated path of the selected key or value, which helps you tell several open windows apart. Under View > Window title you can adjust how the title is composed:
| Option | Effect |
|---|---|
| Value before key | When a value is selected, show the value name before the key path. |
| Reverse key order | Show the key path with its segments in reverse order. |
Additional fine-tuning of the title (such as how many characters of each key segment are shown) is available through the configuration file; see Settings Reference.
