Hi,

Try the following:

Go to Control Panel > Ease of Access Centre, scroll down to Make the keyboard easier to Use

Check the Turn on Toggle Keys checkbox.

Click Apply > OK.

Now you will hear a tone when you press Caps Lock, Num Lock or Scroll Lock. Windows will play an alert beep warning each time you press the Caps Lock, Num Lock, or Scroll Lock keys. These alerts can help you prevent accidentally pressing this key.
