Windows 10: Razer mouse cause ctfmon.exe error in safe mode

My razer mousedeathadder v2 cause ctfmon error like this:ctfmon.exe - System Error: The system detected a stack-based buffer overflow in this application. An overflow could allow a malicious user to gain control of this application.This only happens after the latest windows update, I read somewhere that it is common on razer products like mouse and keyboard. It keeps on popping and when I remove my mouse the problem has been resolved. Now I need to grab a non razer mouse just to get in to safe. mode and use DDU.

Hi,

Thank you for posting your query on Microsoft Community.

I understand the inconvenience caused to you. I will be glad to assist you with your issue.

Follow the below steps and check if it helps.　

If you see the black screen or have a flickering screen:

Step 1: Try connecting to different video outputs on the PC. Sometimes a change in driver can cause the video to be sent:

• • To a different Adapter: from integrated graphics to a discrete card or vice versa.
    
  • To a different output: from HDMI to DVI, Display Port to VGA, or any other combination.
    

Step 2: Try to boot into Safe Mode with Networking
or Enable low-resolution video.

• • Advanced boot options, Safe Mode with Networking, or Low Resolution Video
  • Check Device Manager and look for Display Adapters
    
    • If you see 2 items under Display Adapters, disable to integrated video card (e.g. Intel HD 4000 or AMD Radeon HD 4200) and restart. (try vice versa if it does not work).
    • If you see 1 item under Display Adapters, rollback the driver or uninstall the display adapter in Device Manager, and enable the option to delete driver software.
      

How to boot into Safe mode.

Run your computer in Safe mode and see if you still get that error message. If you are not getting that error message in safe mode then perform clean boot on your computer using the steps provided below. If you
don't get that error message in safe mode then it means that some third party application is causing the problem.

To use a Safe Boot option, follow these steps:

• Restart your computer and start pressing the F8 key on your keyboard. On a computer that is configured for booting to multiple operating systems, you can press the
  F8 key when the Boot Menu appears.
• Select an option Safe mode with Networking using the arrow keys on the keyboard when the
  Windows Advanced Options menu appears, select Safe mode with Networking and then press
  ENTER.

I would suggest you to force shutdown your system and then try to restart it again and check if you are able to login to safe boot.

Check the PC or display adapter manufacturer’s site for an updated driver.

Let us know the status of the issue. We will be glad to assist you.

Thank You.　　

 

ctfmon

Hello,

Ctfmon is the Microsoft process that controls Alternative User Input and the Office Language bar. It’s how you can control the computer via speech or a pen tablet, or using the onscreen keyboard inputs for asian languages. If you are using any of the mentioned
tasks, you should leave it enabled. Since you've already tried removing it at the task manager, we suggest that you follow the steps below to disable ctfmon.exe:

• Open Settings by clicking the Windows icon.
• At the Settings window, type in Administrative tools and select it.
• At the Administrative tools window, click Services.
• At the services window, look for Touch Keyboard and Handwriting panel service, set this to disabled and stop the service. This will disable the ability to use the onscreen keyboard.

Let us know the results.
