Changing the default country/region in Windows changes the default format for numbers, currencies, time, and dates to those usually used for that country/region. For example, if you want to change your default measuring units from centimeters to inches, or display a date as 2009/10/31 instead of 10/31/2009, select the country/region where you are located and the standard measurement systems used in that location are applied to your computer.

This setting affects various features in various Microsoft Office programs, including:

• Calendar in Microsoft Office Outlook.
• Cells formatted with certain date, time, or currency options in Microsoft Office Excel.
