Windows 10: Shift+M does not work

Whenever I use Shift+M it won't type the capital M resulting in me having to use caps lock just. I have plugged in another keyboard and it still does the same thing. I have also used the on screen keyboard and it has the same outcome. This issue has occurred for about 1-2 months and had unexpectedly happened with no lead as to what started the issue.

shift + m key not working!

Hi. Recently my shift + 'm' key isn't working. I know for a fact it worked yesterday because I typed something using a capital m. I've restarted my computer. I've used other keyboards. I've uninstalled and reinstalled the drivers. I'm not sure what else
to do. Any help would be greatly appreciated,

I'm running windows 10, just updated.

Razer Blackwidow Ultimate 2016 edition.

I have not installed any software in the past week.

If any other info is needed i'll be happy to provide it

 

The m, c and shift keys on my laptop keyboard intermittently stop working.

The m, c and shift keys on my laptop keyboard intermittently stop working.

This always happens when the computer starts up from being completely shut down or after it has been in sleep or hibernate mode.

To make m, c and shift keys work again, I press the m and k keys at the same time over and over again until the m key starts working. Then, I hold the m key down and just let it run for a while. After the m key starts working, I press and hold the
c key and just let it run as well.

After the process I just described and after the computer has been running for a while, the m, c and shift keys work just fine. If I close the laptop, which puts it in sleep mode, and leave it that way for a while, the problem returns when I
open the laptop and try to use those keys again.

I have tried a number of suggested fixes I have found on the internet. Including:

Running the Windows 10 Keyboard Troubleshooter - No problem found.

Sticky Key changes in Settings - No help.

Updating keyboard drivers (to include Uninstalling Device) - Didn’t help.

Starting the computer in Safe Mode - The m, c and shift keys don’t work here either.

Running Windows update – No help.

Updating my BIOS – No help.

Cleaning the keys - No help.

Using a USB connected keyboard – this works, no m, c and shift keys problems.

The on-screen keyboard works just fine.

All of the other keys on my keyboard work just fine.



Any ideas?

 

Intel Speed Shift Technology Skylake

You just need a Skylake CPU and ThrottleStop, once turned on speed shift you can exit the software as unclewebb said above.
