After an update, (22H2) my touchscreen stopped working. It didn’t even show up in the Device Manager. Running the device driver installation program from Lenovo did not help. Backing out 22H2 immediately restored my touchscreen.
I thought that was the end of the story, but it stopped working again just now. This time it was still available in the device manager, so I disabled and reenabled it (causing a reboot) and it’s working again. For how long?
