Windows 10: Keyboard keypresses produce irregular results

Pressing a key on the keyboard can produce completely irregular results. Some times the keystroke doesn't register at all some times it registers multiple times. This is a new behaviour that's happening with an old windows 10 installation. They keyboard apparently works fine with my chromebook.


Replacing the microsft wireless keyboard with a mechanical keyboard produces different errors that also don't seem to happen on the chromebook.


The problem appears with multiple programs including videogames.


How do I solve this issue?

Sculpt keyboard does not detect keypress after inactivity, or repeats the keypress

I use Microsoft Sculpt ergonomic keyboard and mouse at home and at work. With both keyboards I have issues with keypresses not being detected or being repeated after the button has been released.

• When pressing a key after a few minutes of inactivity, the first keypress does not register. This is also true when the monitor has been turned off because of inactivity, and when the computer has gone to sleep because of inactivity. The next keypress will
  however always register.
• When pressing a key after a few minutes of inactivity, the key can get stuck repeating the keypress until the key is pressed again. This often happens when I'm watching a YouTube video and presses the spacebar to pause the video. The result is that the
  YouTube player will pause and unpause multiple times a second until I press spacebar again.

I'm running English Windows 10 updated as of 5/22/2017 with the official Microsoft keyboard software installed. One keyboard is Swedish and use the Swedish keyboard layout. The other is Korean and use the US keyboard layout. The wireless receiver connected
to the computer is in both cases about 50cm/20" from the keyboard itself, with only the computer monitor blocking the direct path. In both locations there are WiFi routers close by, and in my office environment there are other computers nearby with wireless
devices.

 

Keyboard irregularity

In Windows 10, my Microsoft Curve Keyboard suddenly switched the @ key with the " key! I want it back. I tried checking languages, but there are no irregularities there. A

 

laptop doesnt boot automatically

This is what happened.

1. Did a repair install and later disabled hibertnate in CMD.
2. Enabled legacy option ROM in BIOS.
3. After a few times startup ( i used the system in such mode for 5 days), changed boot option back to default.
4. Vola!! It boots automatically to win10 without any keypress. Tested it with many starts to confirm the same.
5. Re-enabled hibernate option using CMD and later selected Fast Startup.
6. System booted normally, without the need for any keypress.

I do not know exactly whether such steps resolved the problem or what else happened, hence cannot suggest above steps.

Many thanks to all members who helped to troubleshoot problems.
