What Is Conhost.exe File and Why & How to Delete It [MiniTool Wiki]
What Is Conhost.exe
Task Manager includes plenty of processes such as svchost.exe, ctfmon.exe, rundll32.exe and conhost.exe, etc. So, what is conhost.exe (Console Windows Host) process? To have a deep understanding of conhost.exe, you should know its history. Here, MiniTool will introduce it to you.
In the time of Windows XP, Command Prompt was handled by the ClientServer Runtime System (CSRSS). As the name implies, CSRSS was system level service, which causes several issues. One is that CSRSS could bring down the whole system, while the other is that it could not be themed.
Therefore, the Command Prompt always has the classic look rather than using new interface elements. Then, Windows Vista introduced the Desktop Windows Manager (dwm). The Command Prompt obtained some superficial themes from this. The dwm allowed you to drag and drop files, text and other objects into the Command Prompt.
The Console Windows Host process comes along with Windows 7. It refers to a hots process for the console window. The process is next to CSRSS and the Command Prompt, which enables Windows to draw interface elements correctly such as scrollbars and drag and drop into the Command Prompt.
The new interface elements and styling that have come with Windows 7 are still used in Windows 8 and Windows 10. The console Windows host functions like a shell that has a capability of running a system-level service like CSRSS and integrating modern interface elements safely and reliably.
