System Requirements
O&O DeskInfo is deliberately lightweight. It needs no installation, no database and no background service.
Supported operating systems​
| Requirement | Details |
|---|---|
| Operating system | Windows 11 and Windows 10, Windows Server 2016 or later |
| Architecture | x86, x64 and ARM |
| Framework | .NET 8 Runtime — included in the self-contained build; the portable build prompts for it if missing |
| Installation | None. O&O DeskInfo is a portable application. |
| Privileges | Standard user rights are sufficient for all normal operation. |
| Internet access | Only needed for the end user license agreement, the online help and the optional update check. |
Resource usage​
O&O DeskInfo is designed to stay out of your way:
- Efficiency Mode is enabled by default. Windows then treats the process with low priority and, on supported systems, parks it on efficiency cores. You can toggle it from the tray menu via Use Efficiency Mode.
- The update speed determines how often values are refreshed. Normal (every 5 seconds) is the default; Fast (1 second) and Slow (10 seconds) are available too. See Update speed.
- When Windows goes to standby or hibernation, all timers and performance counters are suspended and resumed automatically on wake-up.
Where O&O DeskInfo stores its data​
| Content | Location |
|---|---|
| Configuration file | %LocalAppData%\OO Software\OO DeskInfo\OODeskInfo.cfg |
| Log files (when enabled) | %LocalAppData%\OO Software\OO DeskInfo\Logs\OODeskInfo.log |
| Temporary export for Notepad | %Temp%\DeskInfo.txt and %Temp%\ProductKey.txt |
If a file named OODeskInfo.cfg is placed next to OODeskInfo.exe, that file is used instead of the one in the user profile. This makes fully portable operation from a USB stick possible — see Configuration File.
Multi-monitor support​
All monitor configurations are supported, including mixed DPI scaling. You can
- place the display on a specific monitor,
- or show it on all monitors simultaneously.
Newly connected and disconnected monitors are detected at runtime. See Desktop Display.
Languages​
The user interface is available in English, German and French. Additional localizations (Spanish, Italian, Russian, Japanese, Chinese) are prepared in the application and appear in the language menu when available. By default O&O DeskInfo follows your Windows display language; you can override it from the tray menu, with the /lang parameter, or with the Language setting.
