Hi, I'm John! I will help you with this.
To help narrow down the issue:
- Is it a laptop, tablet, or a 2-in-1 device (like a Surface)?
- Are you able to use an external USB keyboard or mouse?
- When you open Device Manager, do you see the keyboard and touchpad listed under Keyboards and Mice and other pointing devices?
In the meantime, if you haven’t already already:
To check if the keys are functioning correctly, you can download Keyboard tester from Microsoft Store https://apps.microsoft.com/detail/9n8g1skzc1mb and press the keys that are not responding. If they don't register during the test, it's possible that the keys themselves have become defective and may need to be replaced.
If the keys register successfully during the test, it's likely software interference or Windows settings that are causing the problem. Since you've already updated your keyboard drivers and turned off Sticky Keys and Filter Keys, you may want to try reinstalling the keyboard driver. Here's how you can do that:
- Open the Start menu and search for "Device Manager."
- Open Device Manager and expand the Keyboards menu.
- Right-click on your keyboard's name and select "Uninstall device."
- Restart your computer.
- After restarting, Windows should automatically reinstall the keyboard driver for you.
If the issue persists, please provide more details by answering my questions.
