I believe you have a new HP laptop. First you want to check to make sure it is not a hardware problem.
You can the HP Diagnostic test by:

1. Hold the power button for at least five seconds to turn off the computer.
2. Turn on the computer and immediately press the F2 key repeatedly, about once every second.
3. The HP PC Hardware Diagnostics (UEFI) home page displays.
   
   
   
   Run tests and watch the Keyboard test carefully! If there is hardware related, you can then call HP to initiate the repair process. It can be a keyboard controller problem or a software problem?

Hi Snoopy .. I will try that as soon as I get back home ...
It is newish had it since christmas ... been working ok then this happens ..... I have been reading forums I guess a LOT of people are having this issue some think its cortana some other issues but I cant even open CORTANA ... if I try to click on nay of the apps in the start menu it wont open .. but I can click and type into firefox from the desktop icon and use it to type etc etc but it just wont open anything from the start menu or allow me to click on apps from the start menu .... my old vista has been OK since years ago and I may just use that laptop and try to return the windows 10 junk ??
