Conhost.exe – High CPU Usage on Windows 11/10

Written by Robert Bailey
Conhost.exe, short for Console Window Host, is a legitimate Windows operating system process that is responsible for managing console windows in the Windows environment. It is an essential component of the Windows command prompt (cmd.exe) and Windows console applications.

When you open a command prompt or run a console-based application, Conhost.exe is launched to provide the necessary environment for those programs to run. It handles various functions related to console windows, such as drawing the window, processing keyboard input, and interacting with the underlying operating system.

Conhost.exe was introduced with Windows 7 and is present in subsequent versions of Windows, including Windows 8, 8.1, and 10. It replaced the previous console window management process called csrss.exe (Client/Server Runtime Subsystem).

It’s worth noting that Conhost.exe is a system process located in the Windows\System32 directory. However, like any other system process, it is possible for malicious software to use a similar name to conceal itself, so it’s always a good idea to verify the file location and digital signature to ensure it is the legitimate Conhost.exe process.

If you notice that the Conhost.exe process is consistently using a high amount of CPU, it could indicate a problem or an underlying issue. Here are a few possible reasons and steps you can take to address the high CPU usage:
