I installed the Creators update last night, but did not have a lot of time to test it out. The 4c worked after the update and I did not have to reinstall anything related to it. I did not have time to look at the Windows Accessibility features. I only ran the Tobii config and a game to determine it was working correctly.
However, I do have another issue that existed before the Creators update that I had hoped would be solved by that update. When I installed the Tobii software last weekend, the monitors refused to sleep/shutdown and I’ve had to power them off manually at night. The Creators update did not get that working again, so I need to do more research.
