Step-by-Step Tutorial: How to Add Seconds to Clock Windows 11
Before we jump in, know that this process involves editing the registry. Don’t worry, though—it’s pretty simple if you stick to the steps!
Step 1: Open the Registry Editor
Press Win + R, type regedit, and hit Enter.
The Registry Editor is like a backstage pass to your system settings. It’s where all the customization magic happens.
Step 2: Navigate to the Right Path

This is the path you need to follow to find the specific settings for your taskbar and clock.
Step 3: Create a New DWORD
Right-click inside the right pane and choose New > DWORD (32-bit) Value.
You’re making a new setting! It’s like adding a new tool to your toolbox.
Step 4: Name It Correctly
Name the DWORD ShowSecondsInSystemClock.
This specific name tells Windows exactly what you want it to do—show seconds!
Step 5: Set the Value
Double-click your new DWORD entry and set its value to 1.
Changing this value to 1 is the key. It flips the switch to make seconds visible.
Step 6: Restart Explorer

Restarting Explorer refreshes everything, like hitting a light switch to see the change take effect.
Once you’ve completed these steps, your taskbar clock will proudly display seconds, ticking away the moments with newfound precision.
