How to Change the 24 Hour Clock Format to 12 Hour in Windows 10
The steps and screenshots below are taken from Windows 10, but Windows 8.1/8 and Windows 7 also will have the similar settings except how you are reaching the control panel.
1) Go to Control Panel. To see the different ways to reach control panel, read this post.
2) In the category view of the control panel, click on the ‘Change date, time, or number formats’ as shown below.
3) Here you can change the settings of short and long time. If your Windows 10 computer is showing 24 hour clock then the format settings would be in ‘H’, ‘H’ means 24 hour and ‘h’ means 12 hour clock format.
Click on the drop down menu of the short and long time format and change it to 12 hour format by selecting the ‘h’ in the hours.
The ‘tt’ means AM or PM. Obviously when the time format is set to 24 hour clock, it can’t show the AM or PM. When the 12 hour format set, you can select the ‘tt’ to show the AM or PM in Windows 10 or Windows 8.1/7.
Press Apply to make the changes.
Now your time format will change to 12 hour format and show the AM or PM symbol.
Change the AM/PM Symbol and Customize it in Windows 10
Do you want to change the AM or PM symbol to something else just for fun?, yes, you can do that. Most of the Windows Operating Systems allow the change including Windows 10.
Click on the Addition Settings in the formats settings, then select Time.
On the Time tab, type the text you want to display in the AM/PM symbol.
Once you pressed Apply, you can see the change in the system tray.

As a recap, the capital ‘H’ in the short or long time format will show the 24 hour clock in the Windows 10, 8.1 and 7. To change the 24 hour clock to 12 hour clock format, you need to change and select the format with small letter ‘h’. Displaying the ‘tt’ in the 12 hour clock will show the AM/PM symbol.
