The interface displays dates, time, currency, and numeric values using the default Windows locale settings configured in Regional and Language Options.
To override the default Windows locale in the interface, set the Culture to an ISO code such as de-CH for German (Switzerland).
This setting is commented out by default. This means that this setting cannot be used until you remove the <!-- preceding <Culture> and the --> following </Culture>.
The < DisplayLanguage> and < Culture> settings are not required to match, except when < DisplayLanguage> is configured as Arabic (Saudi Arabia). When < DisplayLanguage> is configured as ar-SA, < Culture> must also be configured as ar-SA. However, when < Culture> is configured as ar-SA, the < DisplayLanguage> is not required to be ar-SA.
