Hi Sumeet,

We would like to know more about the issue.

• When did the issue start?
• What troubleshooting steps have you done so far?
• Have you installed the latest updates for Windows 10?
• What is the current version and build number of your Windows 10 PC?

To find out the version and build number of your Windows PC, click Start, type
winver then press Enter.

We'll be waiting for your response.

 

Try checking to see if you can download an updated keyboard driver from Dell's website. Aside from that, I would try running sfc /scannow in an admin command prompt. Corrupt/missing system files can cause all sorts of weird issues. It may not do anything to fix it, but its an easy check to do and doesnt cost anything and certainly cant hurt.

As it works in other OSs, its doubtful that its a hardware issue.

 

I did run sfc and DISM command as administrator. lt completed successfully and showed no errors. i updated all the drivers from dells website already.

 

There was no solution to this problem. Reset or restore is required. I tried two restore points. older one worked.

 

That's really interesting. I'd like to find out why it wasn't working and what caused it.
