Sometime within the last week or so, the touchscreen stopped working on my laptop (Toshiba Satellite C55Dt-A5307). It has had Windows 10 Home since the free upgrade started last summer and never any issues. I did a clean install at that time.

However, now sometime in the last 2 weeks or so the touchscreen has stopped working. I look in Device Manager, and don't see any device that looks like it would be the touchscreen driver. I look at Toshiba's support page and don't see anything for a touchscreen driver.

I have tried using troubleshoot - hardware & devices. It says to Restart PC to finish installing drivers and updates, but doesn't make a difference. After restarting and rerunning troubleshoot it says exact same thing.
