I learned the hard way that installing the "Synaptics driver update for Synaptics Composite USB HID Device" on Windows 7 x64 kills the trackpoint and touchpad of my Lenovo USB SK-8835 USB keyboard.
The uncool thing is that this does
- not list itself in "Installed Updates", so a guide like here or here does not work.
- not list itself in "Programs and Features" (so it does not show when you run
AppWiz.cpl) - not install itself in the "Programs" menu (so there is no uninstaller you can manually run)
What other options do I have to uninstall the particular (optional) Windows Update?
