Windows 10: KB4509478 Synaptics Touchpad Driver Compatibility Problem

I posted as a reply to <link> "https://h30434.www3.hp.com/t5/Noteb...pdate-KB4509478-Synaptics/m-p/7164381#M194726" and wish to bring this symptom to the attention of Microsoft.


After installation of Microsoft update [June 26, 2019 — KB4509478 (OS Build 17134.860)] the Synaptics touchpad ceased to function.


I tried various steps to get it back, without success. Need a solution from HP.


Here is what I've tried:

1. removal of Synaptics Touchpad device using Microsoft Windows 10 Control Panel > Device Manager
2. removal of Synaptics Touchpad driver taskbar widget from Microsoft Windows 10 Control Panel > Programs and Features
3. restart
4. download sp92533.exe (from HP FTP site) v 19.5.10.75 and install
5. restart
6. perform detect new hardware in Microsoft Windows 10 Control Panel > Device Manager
7. set View Hidden Devices in Microsoft Windows 10 Control Panel > Device Manager


Nothing seems to work. I suspect that HP needs to develop a new revision of the driver compliant with KB4509478 and/or Microsoft must repair the update to be compatible with Syntapics Touchpad.

Please help. HP Notebook computer is now becoming difficult to use without Touchpad.

Synaptics TouchPad Problem


I know this is a known issue with Synaptic Touch Pads on Windows 10, and I am having the same problem as well, gestures not working. I have tried a lot of steps that fixed other devices, but didn't helped me one bit. I have an old Acer Aspire 2930 laptop. The software driver installed on my machine came from Windows Update the version is 19.1.3.6. it also appears as Synaptics PS/2 Port Touchpad on Device Manager. I have tried installing the old driver from Acer driver website but unfortunately the installation fails and does not finish, I tried installing it over compatibility mode as well. Any more ideas for a fix?

P.S. I found an old thread about this which was opened 663 days ago, I don't wanna necro that old post that's why I am opening a new one. Steps there did not work for me as well.
