Hi Dinesh, my name is John D. an independent advisor happy to help you with this.
Firstly, you can try running the Keyboard Troubleshooter by following these steps: Type “Troubleshoot” in Windows Start Search box > Click “Troubleshoot” > Scroll down and click “Keyboard” > Run the troubleshooter > Follow onscreen directions.
If that does not work, you can also try uninstalling the Keyboard Driver and reboot the computer to reinstall. Additionally, you can turn off filter keys in Ease of Access, ensure “Turn on filter Keys” is not checked.
If none of these steps resolve the issue, you can try cleaning your keyboard or checking if the USB connection is secure (if you’re using a USB connection). If you have a wireless keyboard, make sure the charge is good.
I hope that these steps are helpful in resolving the issue.
Best regards,
John D.
