- If you want to go back to Windows 10 then you have ten days to roll it back as shown here: https://www.howtogeek.com/751145/how-to-downgra....
If you're unsure and it's still within the 10 day period, you can extend it as shown here: https://www.droidwin.com/extend-10-day-windows-...
- Update the HID touchscreen driver from the Lenovo Support Downloads web page for your exact mode: https://support.lenovo.com/us/en/ It may be for WIndows 10, 8.1, 8 or 7 so check all of those.
In Device Manager if it doesn't show up in any category, from Action tab choose Scan for Hardware changes, then from View tab Show Hidden Devices. Does it show up? Usually installing the driver is the only way to force it. I'd even ask Lenovo for it if you cannot locate it. You can reach their Support or Forums here:

- Expedite install of all Windows Updates in Settings > Update & Security > Windows Update > Check for Updates, including needed restarts, then go back to check again until no more are offered.
Then go into Microsoft Store app > My Library > Get Updates and expedite all Store app Updates, too, until no more are offered.
- Establish a Clean Boot to turn off Startup Freeloaders that can conflict and cause issues:

- Download, install and run a full scan with free Malwarebyes from https://www.malwarebytes.com/mwb-download/ after enabling Root Kit scan in Scan Settings. Clean Up anything it finds and then run again. Turn off Real Time trial in Control panel to keep as on-demand scanner.
- Run System File Checker/DISM in WIndows 11:

- If that doesn't fix it then you can do a Windows 11 Repair Upgrade which reinstalls Windows while saving your files and apps in place, brings it up to the latest version by the most stable method, takes about an hour and resolves most problems: https://www.elevenforum.com/t/repair-install-wi...
Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
