Hi Robert Harutyunyan,
Thank you for posting in Microsoft Community.
I understand that you're having trouble disabling the touchscreen on your Surface Pro 7. Iam here to help and let us work on this together.
Here’s a step-by-step guide to disable the touchscreen:
- In the search box on the taskbar, enter device manager, and then select Device Managerin the list of results.
- Expand the Human Interface Devicescategory.
- Right-click Intel(R) Precise Touch Device, select Disable device.
- Right-click HID-compliant touch screen, select Disable device. If you see two HID-compliant touchscreen drivers, right-click the first, select Disable device, and then repeat the process for the second driver.
I hope this helps! Let me know how it goes.
