Windows 10: Why did Windows updates make my Acer switch 10 touchscreen unusable 2016-now?

Long ago, late 2016, a windows anniversary update made my Acer switch 10 touchscreen unusable. Somebody in this community fixed it for a few weeks, until the next update. I finally shelved my not-really-a-tablet in 2017 because every new update caused the same problem: wherever I touched the screen, small clear circles echoed up and down or across the screen, causing the wrong app to open if anything at all happened. I couldn't even get to the sign-on screen without a mouse. Recently, my son said he needed a computer with a keyboard to write resumes, so I dusted off my, ahem, not-tablet, and

Acer Aspire V5-571P touchscreen not working with Windows 10

My Acer Aspire V5-571P touchscreen (not touch pad) used to work perfectly with Windows 7, but after upgrading to Windows 10 it only works at the Windows 10 login screen. Someone suggested that loading a Windows 8.1 driver for the touchscreen may work, but
I've searched the Acer drivers website and there are no drivers for the touchscreen. I also noticed since my Windows 10 upgrade that the SD card slot stopped working and the HDMI socket didn't work correctly either, but after a recent Microsoft Windows 10
scheduled update both of these now work ok!

Device Manager shows an entry 'HID-compliant touchscreen' by Microsoft; Driver Date 21/06/2006; Driver Version 10.0.14393.351; stated as 'This device is working normally', but obviously this is not working in Windows 10 after my user name and password is
entered on the login screen.

Is there a specific driver which is only compatible with Windows 10 which will make my touchscreen work again?
