Thank you for posting on HP Support Community.

Don't worry as I'll be glad to help, I have a few troubleshooting steps we could try to fix the issue:  

To resolve this issue, perform the following steps to manually re-enable the devices, then update the driver.

1. Connect an external mouse or use the touch screen.
2. Open Device Manager.
3. Right-click or tap on the 12C HID Device and select Enable. The Synaptics HID Touchpad will appear in Device Manager.
4. Right-click or tap on the Synaptics HID Touchpad device and select Enable. The touchpad will function.
   
   Enable Synaptics HID Touchpad.
   
   
    
5. Select Start and click on the Settings icon.
6. Select Update & Security and click on Check for updates.
7. Select Install now to start Windows Update. The driver is updated through Windows Updates.

Hope this helps! Keep me posted for further assistance.

I tried lots of time in this way but it didn't work. And also it's showing that 

This device cannot start. (Code 10)

A request for the HID descriptor failed.
