Hello,

csrss.exe (Client/Server Run-Time Subsystem) is a System process. https://en.wikipedia.org/wiki/Client/Server_Runtime_Subsystem

You should not kill it. Why do you want to kill it?

I wonder if you realise this, but if you manage to do that, the next thing that would happen is that the computer would bug check (that Blue Screen of Death) because a critical process was killed.

The csrss process does control a few things, one very important thing that it does control is console applications.

This is a signature. Any samples given are not meant to have error checking or show best practices. They are meant to just illustrate a point. I may also give inefficient code or introduce some problems to discourage copy/paste coding. This is because the major point of my posts is to aid in the learning process.

Hi,

Thank you for posting here.

**>>How to kill csrss.exe in Windows 10? **

csrss.exe in Windows 10 handles Win32 console and GUI shutdown. It is critical to system operation; therefore, terminating this process will result in system failure.

Hackers and third-party app developers target these types of executable file to lodge an attack because they decode them easily. Most of the time, you cannot even determine the presence of the malware because it’s injected with the same name.However, csrss.exe is pretty essential for the OS, often it leads to high CPU usage that crashes the entire system or black out the memory. Subsequently, the Windows becomes sluggish and you are unable to operate it. Usually, It occurs either for a corrupt user profile or virus infection.

You may end the task of csrss.exe in order to resolve the issue associated with Client/Server Runtime Subsystem. But you can’t disable it as it is a crucial part of Windows operating system. Even if you force this task to end from Task Manager, you will get an error message claiming Access denied. 

When a virus is responsible to cause high CPU usage because of csrss.exe in Windows 10, Perform a Full Scan to remove them. Windows Defender which is a built-in antimalware tool will help you in this regard.

If Full scan didn’t work for you, there is unabridged possibility that corrupted user profile is causing issues related to Client/Server Runtime Subsystem. In this situation, replacing the same with a new one will be the best solution to fix the issue. Corrupt files obstruct the procedure of configuring user profile properly which has somewhat concern with csrss.exe in Windows 10. The whole process ends up with high CPU usage.

If the above method doesn’t fix high CPU usage, the final thing you can do is Reset. It will completely Restore your computer with initial values and disable csrss.exe in Windows 10 surely.

Note: Before starting this workaround, backup your important files to an external memory.

Hope these methods are useful to you.

Best Regards,
