Summarize this article in one sentence.
Click the Windows logo in the bottom-left corner of the screen. The Start menu will pop up. Type in command prompt, then wait for Command Prompt to appear at the top of the Start menu. It's at the top of the Start menu. A drop-down menu will appear. If your mouse doesn't have a right-click button, click the right side of the mouse, or use two fingers to click the mouse. If your computer uses a trackpad instead of a mouse, use two fingers to tap the trackpad or press the bottom-right side of the trackpad. This option is in the drop-down menu. You can't change your computer's time and date without administrator privileges. Doing so confirms that you want to open Command Prompt; you should see the Command Prompt window appear at this point. The command for changing time in Command Prompt is time HH:MM:SS AM/PM where "HH:MM:SS" refers to the hour, minute, and second, and "AM/PM" refers to whether it's morning or afternoon. To change your computer's time, type in this command with your preferred time indicated, then press Enter. For example, typing in time 08:35:00 AM and pressing Enter would change your computer's time to 8:35 AM. To change the time to 10:00 PM, you would type in time 10:00:00 PM and press Enter. If you're comfortable with 24-hour time, you can type in your preferred time (e.g., 14:00:00 for 2:00 PM) and leave off the "AM" or "PM" tag. The date format you'll use in Command Prompt depends on your country, but Command Prompt will tell you which format to use: type in date and press Enter, then type in the date you want to use in whichever format is specified by Command Prompt (e.g., "mm-dd-yyyy" in the United States) and press Enter. To change a United States computer's date to September 25th, 2018, you would type in date and press Enter, then type in 09-25-2018 and press Enter. To adjust the date to read October 12th, 2018 on a European computer, you would type in date and press Enter, then enter either 12-10-2018 or 2018-10-12 depending on your location. In the bottom-right corner of the screen, you should see both your updated time and your updated date reflected in your region's format. If you use 24-hour time, you won't see "AM" or "PM" listed here.
