I'm using a CD-R King M series mouse. Is there some way I can turn off the middle mouse button light? My computer runs Windows 7.

In order for someone to answer that question, you would need to specify the brand and model of mouse and your operating system. – CarlF Mar 14 '11 at 12:49

Unlikely - the light is probably the same one that does the sensing of movement. – Majenko Mar 14 '11 at 13:35

There's a general way:

  1. Download AutoHotkey, a great freeware script language.
  2. Install it, together with its editor (SciTe4AutoHotKey).
  3. Click File > New.
  4. Use the following code:

  5. File > Save, select a name (e.g. mouse.ahk)

  6. Put a shortcut for this file in your Startup folder.
  7. Restart the computer.

A little hardware hacking could help.

I don't know details about your mouse but a little screwdriver and a little (more) patience could let you find out what produces the light (probably @Matt Jenkins is right) and if you can turn it off or just use a little black sello tape to hide it.

Have fun :)
