Windows Vista: The Complete Reference (Complete Reference Series)
Windows comes with predefined regional settings for most of the countries in the world. Regional settings affect the format of numbers, currency, dates, and times. For example, if you choose the regional settings for Germany, Windows knows to display numbers with dots between the thousands and a comma as the decimal point, to use Deutsch marks as the currency, and to display dates with the day preceding the month.
| Note | To reset your keyboard for other languages, see "Changing Language Properties" earlier in this chapter. |
To see or change your regional settings, look in the Regional And Language Options dialog box, shown in Figure 13-5. To display this box, open the Regional And Language Options icon from the Clock, Language, And Region category of the Control Panel.
Telling Windows Where You Live
Windows has predefined sets of regional settings, so you needn't select numeric, currency, date, and time formats separately. Choose the language you speak and the country where you live from the drop-down list in the Current Format list on the Formats tab of the Regional And Language Options dialog box. The list is arranged alphabetically by language, with the country in parentheses. There are, for example, 16 English entries, including English (Belize) and English (South Africa).
Setting Number, Currency, Time, and Date Formats
After you tell Windows which language you speak and where you live, it displays sample numbers, currency symbols, times, and dates on the Formats tab of the Regional And Language Options dialog box. You will probably be happy with the way these samples are formatted. If not, you can change any of these items individually by clicking the Customize This Format button. When the Customize Regional Options dialog box appears (see Figure 13-6), click the Numbers, Currency, Time, or Date tab to see the corresponding settings. You can customize settings that appear in white. Those that are in gray have set formats from which you can choose. To change any of these settings, make another selection from the corresponding drop-down list and click the Apply or OK button.
