Certain programs make my computer act as if certain keys are pressed down

Hello,

Recently, I've been having a very strange issue: while running certain programs, my computer suddenly begins to act as if certain keys on my keyboard are being pressed. In the beginning, it acted as though the CTRL key was pressed (ex: pressing "w" executes
the "CTRL + w" command). Now, it acts as though my "c" and "v" keys are being pressed (when typing, a string of cs and vs are rapidly typed across the screen). Opening the onscreen keyboard confirms that my computer thinks that the keys are being pressed.
Only restarting my pc temporarily fixes the issue. Here's what I've done to try to remedy it:

• press both CTRL keys for 15 seconds
  
• turn off sticky keys, toggle keys, and filter keys
  
• switch out my keyboard
  
• plug my keyboard into a different usb port
  
• uninstall and reinstall my keyboard drivers
  
• hold CTRL + Shift for 15 seconds
  
• reinstall windows
  
• run system file checker
  
• enter safe mode
  
• uninstall and reinstall all of my usb drivers
  
• check for malware
  

The problem with the CTRL key happened no matter what program I was using, but the problems with the c and v keys have only started while playing a game. Any help in fixing this issue would be greatly appreciated. Thanks!

 

Certain keys on the keyboard are not working properly.

Hi Russell,

Thank you for posting your question in the Microsoft Community.

I understand that certain keys on the keyboard are not working properly on the pc. I will try to help you with this issue.

Please answer these questions to get more clarity on this issue:

• 
  Did you make any changes to the pc prior to this issue?
  
• 
  Have you installed all pending updates on the pc?
  
• 
  Have you performed a full pc virus scan on the system recently?
  

Suggest you to launch the on-screen keyboard to check if the issue persists.

Follow these steps to launch the On-screen keyboard:

• 
  Press “Windows key + R” to get the run window.
  
• 
  Type “osk” and hit enter to launch the On-screen keyboard and check if this helps.
  

Also suggest you to install any pending Windows updates on the pc to check if that helps.
Updates are additions to software that can help prevent or fix problems, improve how your computer works, or enhance your computing experience.

Further, you may also boot the computer in a clean boot state and check if the issue persists. When you start Microsoft Windows, typically there are several programs that start automatically and run in the background that may interfere with the system.
These programs may include antivirus and system utility programs. When you perform a clean startup procedure, you prevent these programs from starting automatically.
