Touchpad Works in BIOS but Not Windows

[jasonklamm]

I've tried all of the basics (uninstall/reinstall, install old drivers [doesn't take], disable/enable, reinstalled Windows TWICE), but recently my touchpad has stopped working while in Windows. It DOES work in the BIOS screen, etc, however.  I have tried updating drivers, including optional updated in Windows update, and nothing solves it. I've tried all variations on enabling/disabling/uninstalling the touchpad.

ERROR in Device Manager:

This device cannot start. (Code 10)

The device returned an invalid HID descriptor.

My laptop has no such sticker on it, sorry. And I bought it direct from HP. Is there another way to find it?

Whenever I use this option it always tells me "the best drivers for your device are already installed," so this time I did "Let me pick from a list of available drivers" and then clicked "Have Disk." I navigated to the cab file and chose EPD.inf (there are three options, so I wasn't sure which to use) and I get this:

I went through with it and rebooted but it didn't work.
