Hi GouravAB -
I'm Jerico T., one of the Independent Advisor and a fellow Windows 10 user like you. I understand that you're having some issues right now, let us sort things out.
Have you tried using an external/USB keyboard to check if it's a hardware issue? If so, please try to perform a rollback or your driver and check if it will fix your concern.
Roll-back driver
- Open run box by pressing Windows Key + R and type devmgmt.msc then hit enter
- Locate and expand Keyboards
- Right-click on the driver and select Update driver
- Select Browse my computer for drivers
- Select Let me pick from a list of available drivers on my computer
- Select any older driver from the list and click next
- Wait for the process to complete, once completed, restart your computer and check if it resolves your issue.
Feel free to reach back if you need any further assistance.
Hope this help. Have a good day.
Thank you.
Jerico T.
