Keyboard Keys That Stick, Repeat, or Stop Working
My Windows 10 keyboard is exhibiting erratic behavior where certain keys physically feel fine but either fail to register input, repeat characters multiple times with a single press, or become comple...
Hi, because this happens across Notepad and browsers, I would test both accessibility settings and hardware.
Check Settings > Ease of Access > Keyboard and turn off Sticky Keys, Filter Keys, and Toggle Keys. Then open Keyboard properties and set the repeat delay/rate back to normal. After that, test with an external USB keyboard for a while.
If the external keyboard works perfectly, the built-in keyboard is likely failing even if the keys feel okay. If both keyboards have the same issue, uninstall the keyboard devices from Device Manager and reboot, then check for chipset/keyboard firmware updates from the PC maker.
A good extra test is the BIOS/UEFI screen. If keys repeat or fail there too, Windows is not the cause.
