This is done by going to the Control Panel and clicking on the “Time and Language” tab. There, you will need to select the “Military Time” check box. Once you have checked this box, your computer will start displaying military time in your clock and other settings.
To change this setting, we’ll need to get to the Regional and Language Options screen. The easiest way to do so is just enter intl.cpl into the Start menu search box and hit enter. Otherwise, type region into the Control Panel.
From the Regional and Language Options dialog, click the “Customize this format” button, and then select the Time tab.
