# General options

These options decide DU Meter's language, when it starts, and what it sends to Hagel Technologies.

### Display language

The language of DU Meter's windows, menus and e-mails. It applies to every user of this computer, and only an
administrator can change it. DU Meter switches at once; a window that is already open takes the new language
when it is opened again.

### Start DU Meter with Windows

DU Meter starts each time you sign in to Windows. This is the default. The DU Meter service is always active,
counting traffic and showing alerts, so DU Meter can be closed when you do not need to see the traffic.

### Privacy

**Help improve DU Meter by sending diagnostic data**: DU Meter tells Hagel Technologies which features are used and
which errors it runs into, so that we can fix bugs and improve DU Meter. That is a few kilobytes a week, and a report
when an error occurs. It applies to every user of this computer, and only an administrator can change it. Our
[privacy policy](https://www.hageltech.com/about/privacy) says what the reports hold.

### Check for updates

DU Meter checks for a new version now and then by itself, and tells you only when there is one. This button
checks now. DU Meter does **not** download or install updates: it tells you where to get them.

### Show taskbar band

On Windows 10, DU Meter can show inside the taskbar as a band. This button asks Windows to show it, and Windows
asks you to confirm. To remove the band, right-click it and choose Close this taskbar band. Windows 11 has no
taskbar bands and no such button: drag DU Meter's numbers onto the taskbar instead, as
[The graph and the numbers](https://www.hageltech.com/support/kb/du/using/graph_and_numbers) describes.
