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.

Hey everyone, I just got this issue after installing VMWare Workstation 15 and the fix for it was the below steps:

1 - Navigate to the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}


2 - Once you find the two folders, there is no need to expand them further (if you do, you'll find folders labeled "0000", "0001", "Properties", etc. -- just ignore these).
3 - To fix the keyboard, click directly on the 4D36E96B-E325-11CE-BFC1-08002BE10318 folder (don't expand it). Once you click the folder, you'll see registry value files appear on the right hand side.
4 - The file you're looking for is the last one in the group -- the one named UpperFilters. Double-click on it, and a small box opens titled "Edit Multi-Screen"
5 - Once the Edit Multi-Screen box opens, you want to delete any information in the Value data: field (if there is any), and type kbdclass When finished, click the OK button.
6 - Reboot your system and I hope the issue will be fixed.
