Conhost.exe is an important Windows process. The full name of Conhost.exe is Console Windows Host, and it can be seen in the Processes tab in the Task Manager of Windows 10. Conhost.exe is associated with csrss.exe (ClientServer Runtime System Service) and cmd.exe (Command Prompt) processes.
The primary purpose of conhost.exe is that it adds some nifty external features to the Command Prompt in Windows 10, which the previous versions of Windows lacked. For instance, due to conhost.exe, the Command Prompt in Windows 10 uses the same window frame as the other programs use.
In order to wrap your head around the concept of conhost.exe, it’s important to know a few things about Windows Command Prompt and the processes associated with it.
What is Conhost.exe?
Conhost.exe is a process that you can see in the Processes tab in Windows Task Manager in Windows 10. It is actually a process that Windows 10 runs on your system when it’s up and running.
Command Prompt is one of the ‘signature’ applications of the Windows operating system. It is actually a command line interpreter application that is used to execute commands, which, in turn, automate tasks via scripts and batch files, and ultimately do a ton of tasks. You could execute a variety of administrative actions and resolve or troubleshoot certain Windows issues.
what the Command Prompt of Windows 10 looks like:
In short, you could literally turn the entire operating system upside down if you know your way around Command Prompt.
Back in the days of Windows XP, the Command Prompt was handled by a process called ClientServer Runtime System Service (CSRSS).
Now, a notable thing about CSRSS is that it was a system-level service. So, it had a couple of drawbacks. For example, if CSRSS crashed, it could bring down the entire system. This was not just a reliability issue, but also a security concern. You don’t want to have your entire system crash just because of a problem in a single process.
Furthermore, since the developers didn’t want to risk theme code to run in a system process, the CSRSS was not themed. As a result, the Command Prompt in those days had the old, classic look, as opposed to the modern, stylish look it has today.
This can only be understood visually, so here’s an example:
Windows 7 and Conhost.exe
When Windows 7 took over, the Console Window Host process, a.k.a. conhost.exe, also saw the light of the day. It’s a process that ‘sits’ in the middle of CSRSS and Command Prompt (cmd.exe).
It not only fixes the theme and user interface issue that we discussed earlier, but also lets you drag and drop files directly onto Command Prompt, a feature that was not available in the previous versions. This has all been made possible due to conhost.exe, which is why you see conhost.exe under Processes in the Windows Task Manager.
Although you see conhost.exe as a separate entity than the CSRSS in the task manager, the former is still closely related to CSRSS. You will see, in fact, that conhost.exe runs under the csrss.exe process in the task manager.
All in all, suffice to say that conhost.exe is akin to a shell that facilitates running a system-level service like CSRSS, while still affording the ability to integrate modern interface themes and elements.
Is conhost.exe a virus?
The answer is: no, conhost.exe is not a virus. It’s actually an official component of the Windows operating system. As such, it’s completely harmless by itself.
However, it is POSSIBLE that a virus could replace the real Console Window Host (conhost.exe) with an executable of its own. Although it’s unlikely, you could still check the authenticity of conhost.exe by right clicking on it and choosing the “open file location” option.
If it’s stored in the Windows/System32 folder, then you’re all set; if it’s stored in some other folder, it might potentially be a virus.
That’s why it’s essential to have a good antivirus program protecting your system against such virus and malware attacks.
