I have an HP Envy TS 15 Notebook and I had this exact problem. I was able to fix it by disabling all the HP SimplePass applications in the Task Manager.
Go to the Task Manager(Ctrl+Shift+Esc) > More Details(bottom left) > Startup Tab >
Find anything that is labelled HP SimplePass and Disable it.
I hope this works for you all, as it did for me.
Also, I know the HP Accelerometer had compatibility issues with the new version of Windows 10 as well. You might have to disable that or try to get the new driver for it.
