Hello Brett,
I faced the same issues (touch screen, the facial recognition via Windows Hello) not working after a few minutes of inactivity.
I have performed the steps below yet do not result in a permanent solution.
- Performed Surface Diagnostic Toolkit but no irregularity displayed.
- There is also no remaining Windows Update.
- System File Checker - The restore operation was completed successfully with Verification 100% completed
Windows Resource Protection did not find any integrity violations.
- Uninstalling HID-Compliant Touch Screen and Intel(R) Precise Touch Device in Device Manager doesn't work.
- Restarting the device only works as a temporary solution as the same issue reoccurs after a few minutes of inactivity.
It is doesn't make sense to restart every single time and I'm looking for more of a permanent solution.
Appreciate it if you could share any solution shared by Microsoft Support. Thank you
