Editing the Registry

Warning: The Registry Editor is a powerful tool and misusing it can render your system unstable or even inoperable. This is a pretty simple hack and, as long as you stick to the instructions, you should not have any problems. If you have never worked with the Registry Editor before, consider reading about how to use the Registry Editor before you get started. And definitely back up the Registry and create a System Restore point before making changes.

First, open the Registry Editor by clicking Start, typing “regedit” into the Cortana search box at the bottom of the Start menu, and pressing Enter. Give the Registry Editor permission to make changes to your PC. Refer to the below image:

Selecting the Registry Editor

Next, use the left sidebar to navigate to the following key in the Registry Editor:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced

See the below image:

Clock 2
Accessing the Advanced Key

Now, right-click the Advanced key in the left pane and select:

New > DWORD (32-bit) Value

See the following image:

Next, name the value

ShowSecondsInSystemClock

and press Enter. If you type “Sustem” instead of “System” or “Second” instead of “Seconds” in the name, these will not work, it must be the exact wording. Refer to the below image:

Clock 4
Naming the new Key

Now, double-click the value you just created, enter a value data of 1, and click OK. See the below image;

Assigning the value of 1 to the new Key

Next, you can now close the Registry Editor. You will have to sign out and sign back in again before your changes will take effect. To view the Clock with seconds, view the Date and Time in your System Tray in the lower right-hand corner. See the following image:

Making duplicate copies and computer printouts of things no one wanted even one of in the first place is giving America a new sense of purpose.
