Windows key automatic working | Tom's Guide Forum

My laptop Toshiba satellite c640,In this time keyboard working but L press lock and R press run mode , am not press windows key . and am using on screen keyboard , but same problem, what i do.. 

Try this…1. Uninstall the keyboard driver.2. Reboot the computer (without reinstalling the driver).3. When it restarts, it should reinstall the driver on its own.If this doesn\’t work, you may wish to try connecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue.You may also want to try updating the Synaptics Driver if the above doesn\’t help.
