Installed Windows 10 a few days ago (I didn't seem to have the option not to) and now my HP laptop scroll bar has stopped working. Synaptics PS/2 Port TouchPad Properties show the device status as "This device is working properly". If I opt to rollback to the previously installed driver, I'm concerned that this might not be compatible with W10 and then I'll be in real trouble. I have to admit to being fed up, after less than a week, with having to use the arrows on the screen scroll bar or two fingers on my touchpad to get around my computer - arghh! Don't anybody ask me how I like W10! Any help, hopefully not too technical, appreciated - I'm into arts and humanities, not IT
