Typing language into the search bar ( I have Windows 7) I found a bit called Region and Language, this bit was from the Help page concerning changing the language;
1.Apply regional and language settings to reserved accounts.
2.Click to open Region and Language.
3.Click the Keyboards and Languages tab.
4.Under Display language, choose a language from the list, and then click OK<- From the Help page about changing the language.
Note
If you don't see the list of display languages, you need to install additional language files.
EDIT: I don't know what it would be called in German, but the icon was a little clock-face in front of a globe. http://i.imgur.com/jZZLl.jpg thought you could use it to look for one in German with a similar layout
