Want to make your keyboard's LED indicators dazzle? Utilize a simple Visual Basic script to toggle the Num Lock, Caps Lock, and Scroll Lock keys, creating a mesmerizing light display. This prank works on any Windows computer.
Steps

Launch Notepad. Craft a swift script to cycle the keyboard LEDs for Caps Lock, Num Lock, and Scroll Lock in Windows. Ensure your keyboard features these LEDs typically situated in the upper-right corner.

Paste the code below into an empty Notepad file. This VisualBasic script loops the lights, enabling it to operate on any Windows system. Get ready for a captivating keyboard light show!

Open the 'Save As' Dialog Box. Navigate to the File menu and choose 'Save As'.

Change the File Type to 'All Files (*.*).' This enables you to save the text document in a different format.

Add the '.vbs' Extension to the File Name. This designates it as a Visual Basic script. For instance, you might name it 'keyboardshow.vbs.' Consider renaming it for a playful surprise.

Save the File. Select a convenient location, such as your desktop or Documents folder, to save the file.

Execute the Script. Double-click the created file to initiate the script. A dialog box will display 'Look at your keyboard for a cool light show!' while the indicator LEDs cycle on and off. This script is compatible with any Windows computer.

Access the Task Manager to halt the script. The light display will persist until you intervene. To do this, access the Task Manager. You can do this by pressing Ctrl+Alt+Del and selecting 'Task Manager,' or by pressing Ctrl+⇧ Shift+Esc. Ensure someone knows how to deactivate it if used as a prank.

Access the 'Processes' or 'Details' tab. This will list all active processes. If these tabs aren't visible, click 'More details.' In Windows 10, both tabs exist. Choose the 'Details' tab.

Locate the 'wscript.exe' process. Typically found at the bottom of the list.

Right-click on 'wscript.exe' and choose 'End task'. Confirm to terminate the process, restoring the keyboard's normal function.
