My laptop, Lenovo IdeaPad 520, has Synaptics driver for the touchpad. It's up-to-date. Something weird happened to it and all of a sudden the check boxes and radio buttons in Mouse Properties window and the Synaptics touchpad settings window have disappeared. I am not able to make selections and ensure that correct settings are selected. Here're the screenshots:-
Today after I installed a third-party driver which came with a program called vJoy (used for gaming purpose). After that driver was installed, the Windows sounds for peripherals disconnection/connection were emitted and I noticed that the Synaptics tray icon was shown on the taskbar which caused me to suspect that the third-party driver did something to my touchpad but didn't know what. Also, I'm not sure if this is the actual reason for this weird problem.
When I opened the touchpad settings, I noticed that those selection buttons had disappeared. Even after uninstalling the third-party driver and deleting its related registry entries, nothing changed. I also uninstalled and deleted Synaptics' driver, restarted the laptop and installed it again. Still didn't work.
What could be the issue? Thanks.

I have the very same issue with my Lenovo Yoga 514 AST.
Just installed Windows 10 build 17025 preview, from scratch, on a newly formatted HDD.
Some other checkboxes are also missing, in installshield based driver installation utilities :
Normally, there would be a check box here. But it's not displayed...

The only time I've personally seen anything like that was with particular screen scaling options - and it wasn't with something as basic as the installer GUI.
I doubt that is what is going on but try different scaling options.
