How to Change the Windows Clock to Military Time

1. Click the 'Start' button on your desktop's toolbar. If you haven't changed the default settings, it is located in the bottom left-hand corner of the computer screen.
2. Using your mouse, highlight the option that says 'Settings' and then move your mouse to the right to highlight 'Control Panel.' Click once on the 'Control Panel' button. This opens the 'Control Panel' folder window containing a list of icons, including but not limited to 'Add/Remove Hardware,' 'Date and Time,' 'Display,' and 'Regional and Language Options.'
3. Double-click the 'Regional and Language Options' button. This opens the 'Regional and Language Options' window.
4. Click the 'Customize...' button next to the drop-down menu in the 'Regional Options' tab. This opens the 'Customize Regional Options' window.
5. Click the 'Time' tab in the 'Customize Regional Options' window. The 'Time' tab is the third tab at the top of the window.
6. In the drop-down menu next to 'Time format:' click on the down arrow to bring up a list of options. Using your mouse, highlight any of the options starting with a capital H and select one by clicking the left mouse button. The formats beginning with a capital H represent 24-hour military standard time.
7. Click the 'Apply' button in the bottom right-hand corner of the 'Customize Regional Options' window. Your computer's clock (located at the bottom right-hand corner of your screen) should display the new format.
8. Click the 'OK' button at the bottom of the 'Customize Regional Options' window and then click the 'OK' button at the bottom of the 'Regional and Language Options' window. Alternatively, you can also exit the windows by clicking the 'X' button at the top right-hand corner of each window.
