Some times our computer will act too smart and it will show you what it can do. The situation may be with the monitor, Device drivers, operating system and even with mouse and Key-Board too...

         You know how difficult it is that you are getting the letters "io" while you tying the letter "o".


Yes, in my case my laptop key-board has shown me what it can do in the above case. From that frustration I am writing this post to share my temporary solution to put a Full-stop to my key board's worst behavior. The reason for the miss behavior of the key-board may be faulty key-board drivers or the faulty keys. If the issue is with drivers, then we can change it. Temporarily you can use external USB keyboard or "On Screen Keyboard (OSK)" app which can enables you to type the letters using mouse.
If internal keyboard of laptop annoying even with out any key press the you have to completely disable it, here the procedure to do it.
 To deactivate the Physical keyboard

       Right click on the Mycomputer--->Properties--->Device manager(situated in left side)

Now in the device manager window find the "Keyboards" and click on the "+ " sign, then the your key board device will be shown.
        Right click on the keyboard device--->properties --->Driver tab-->Disable


Now you had successfully disabled the Physical keyboard drivers. The keyboard will be disabled during the next boot, but after restarting your PC, the keyboard will be activated (Plug & Play) as usually. To avoid this and to disable the keyboard until you enable it, just follow the steps below
  • Open run application  or press windowkey+R
  • In "Run" window type gpedit.msc, it will open the "Local Group Policy Editor" Window.
  • In Gpedit window in the left navigation panel choose 
    computer configuration--> Administrative Templates-->System-->Device Installation-->Device Installation Restrictions-->Prevent Installation of devices not described by other policy settings

now double click on "Prevent Installation of devices not described by other policy settings" and select "enable". 

That's it, now restart your PC and you can check that your internal key board is not working. Your Lap-Top Internal keyboard will remain in disabled mode until you reset the policy "Prevent Installation of devices not described by other policy settings"  as "not configure ". 
Note: Do the above setup after inserting USB Keyboard, if not so, USB keyboard may not work because drivers will not installed.
