How to Disable Dell Mouse Stick Pointer on Windows 7

I personally find this Dell mouse stick pointer very annoying. It always messes up my typing. Thus I always had it disabled. All of a sudden, today it is enabled. It turns out that Dell Touchpad application no longer exists in my laptop. I don't understand how and why this could happen. It could be related to Windows update. In order to disable it, I have to re-install Dell Touchpad application. After the reboot, Dell Touchpad will show up in Mouse Properties so that I can configure it. The following is the procedure of how to disable this mouse stick pointer.

• If you don't have Dell Touchpad application installed, go Dell Support site to download and install it. Most of time, a reboot is required after installation.
• Go Control Panel.
• Select All Control Panel Items.
  
  
  
  Or type mouse at the search box and then select Change mouse settings.
  
  
  
  
• If you have Dell Touchpad application installed, Dell Touchpad tab will show up. Click on the image inside the Dell Touchpad tab content.
  
  
  
  
• Select Button Settings from Dell Touchpad window.
  
  
  
  
• Select Device Select tab and click Disable radio button of Pointing Stick and then click Apply.
  
  
• The mouse stick pointer will be disabled instantly. Click OK and then exit the Dell Touchpad application.
