I'm sorry about the issue. When did this issue first occur?
What's the model of your Windows 10 computer?
1. Please try to do a system restore, and check:
Right-click (or press and hold) the Start button (which is the windows logo icon at the bottom left of the computer's screen), and then select Control Panel.
Type / search for Recovery in Control Panel.
Select Recovery > Open System Restore > Next.
Choose the restore point related to the problematic app, driver, or update, and then select Next > Finish.
2. If that does not work, uninstall the Keyboard driver from Device Manager, then restart the computer and check:
3. If that still does not work, please do a reset:
- Click on Start (which is the windows logo icon at the bottom left of the computer's screen), then click on Settings, then click on Update & security, then click on Recovery, then click on Reset PC, then when prompted, click on the option Keep my files and continue, and check.
Please reply at the box below to continue troubleshooting. Thank you.
