Conhost.exe, called the Console Windows Host file, is legitimate and offered by Microsoft. You should run this so that Command Prompt works with Windows Explorer. With the help of the feature, you can drag and drop files into Command Prompt directly. When any third party requires access to the command line, it can use conhost.exe as well.
If you find something is going wrong with your PC, then you need to pull up the Task Manager and find files that may seem to you in such a way as these do not belong. conhost.exe is one of the files which stands out the most. It is a necessary file that can be found running always, and it doesn’t depend on the version of the PC you use.
What is conhost.exe?
Conhost.exe refers to Console Windows Host that you can find in the Processes tab of the Task Manager. In addition, the file has connections with csrss.exe and cmd.exe, referring to ClientServer Runtime System Service and Command Prompt processes, respectively.
What is Conhost File’s job?
It can add some external specifications to the command prompt. The earlier Windows versions didn’t come with these. For example, Command Prompt uses the same window frame due to conhost.exe as other programs.
This one is a crucial part of running windows on the PC. It is also a recent addition to this procedure. Conhost.exe was specially made for Windows 7 to simplify the heavy burden that is put on the csrss.exe file.
What Does Conhost.exe Do?
Basically, the main job of conhost.exe is shifting a few elements of running the system-level services from csrss.exe so that it can permit additional customization and security. While the moving process of the elements is going, Windows can do more theme-related elements so that there will not remain any risk of corrupting the csrss.exe file.
Software that use Conhost.exe:
You can start the process using every example of CMD and programs that use the command line tool, even though you cannot see the program running like its performance in the background.
These are a few processes that can start conhost.exe:
- Dell’s “DFS.Common.Agent.exe”
- NVIDIA’s “NVIDIA Web Helper.exe”
- Plex’s “PlexScriptHost.exe”
- Adobe Creative Cloud’s “node.exe.”
Is Conhost.exe a Virus?
Most people don’t think that it is a virus or they need to delete it. However, users should check a few things if they are unsure about this.
If you are a beginner and find this running in Windows Vista or XP, it is probably a virus or maybe an unnecessary program. The reason for that is these windows versions do not use the file. Have you seen conhost.exe in any of these windows versions? Then, navigate to the page’s bottom to see what you should do.
The file may be malicious or fake if it is in the wrong folder. The original file runs from a particular folder. Therefore, using Task Manager to do a few things, like verifying its description and checking the folder from which it’s running, is one of the simplest things to learn if the process is harmful or not.
You should first open Task Manager by hitting the Ctrl+Shift+Esc keys on the keyboard.
You need to look for the process in the Details tab. If you use Windows 7, find the Processes tab.
You should follow these steps now because several instances of conhost.exe are available. However, if you want to gather all conhost.exe processes, choose the Name column to sort the list. If you don’t see any tab in Task Manager, you have to use the More details link, which is available at the Task Manager’s bottom section, so that you can expand the program to full size.
You must see the far right section below the Description column within that conhost.exe entry, ensuring that it can read Console Windows Host.
The correct description never indicates the safety of a process because a virus may use the same description. But if you get to see another description, it may happen that the .exe file is not the real Console Windows Host process. So, it can be treated as a threat.
You should tap on the process and select Open file location.
The folder will display where the file is available.
You need to use Microsoft’s Process Explorer program if you cannot open the file location following this process. In this case, you need to tap twice to open the Properties window. After that, you should use the Image tab, letting you find the Explore button, which can be seen near the file’s path.
Why Are There Several Instances of the Console Window Host Process Running?
As a user, you can get to see several examples of the console Window host process which runs in Task Manager. Every example of cmd can create its Console window Host process. Besides, other applications that use command lines can create their Console Windows Host process even if the user can’t get to see an active window available for them. The Plex Media Server app is a good instance that can run in the background. Besides, it may use the command line so that other devices can find this on your network.
Several apps running in the background can work this way. Therefore, you may see many examples of this process that run at any given time. In most cases, every process consumes little memory, below 10 MB, and zero CPU when the process remains inactive.
Why is Conhost.exe Using So Much CPU and Disk?
If you find any specific example of this process causing issues such as continual excessive CPU or RAM usage, check into particular apps that get involved in finding a minimum concept of where to start the troubleshooting procedure. However, it is unfortunate that the Task Manager can not offer good information about it.
Microsoft can offer an extraordinary tool to work with processes as being part of its Sysinternals lineup. Hence, you only need to download Process Explorer and run this. Moreover, as the app is portable, you do not have to install it. Furthermore, it can offer several advanced specifications.
Tapping Ctrl+F enables you to begin a search. It is the simplest way to track down these processes. Then, you have to look for “conhost,” and your task is to tap through the results. Then, the main window will appear to display the app connected with that specific instance of the console window host. If you get notified by CPU or RAM that this instance is creating issues, then you need to narrow it down to a specific app.
Can you remove it?
It is a vital file. Due to which, you should not remove it. This file is linked to csrss.exe and cmd.exe. Therefore, removing it indicates your Windows OS will not be able to function.
How to Remove a Conhost.exe Virus:
Have you found the file a virus? If it is, then you should know that you can delete it easily from the PC.
First, you should try to shut down the parent process which uses the file. It prevents the process from running malicious code. Do you know which program can use conhost.exe? If you know, then skip the steps given below. Next, you should attempt removing the app expecting that you can remove the linked virus as well. Hence, you need to use a free uninstaller tool to ensure that all are deleted.
- Your first task is to download the Process Explorer. Then, you need to double-click on the file which you are willing to remove.
- After that, you should go to the Image tab to choose Kill Process.
- Next, you should tap on OK for confirmation. Finally, you should try running a virus scan when you see that it is impossible to shut down the process.
- Hit OK so that you can go back to the main display. If you want, shut down the Process Explorer at this time.
The file is now disconnected from the parent program, which has started this. You should try to reboot the PC and check if the conhost.exe is removed. If you are willing to remove it, you need to run Task Manager or Process Explorer every time you restart to ensure that you have deleted the virus.
You should try to delete conhost.exe. After that, you need to open the folder from the fourth step mentioned above and delete this.
You may use Everything for doing a complete search on your PC, ensuring that the file you are viewing is in the \system32\ folder. For example, there could be another file in the C:\Windows\WinSxS\ folder, but it is not the one which can be found running in Task Manager or Process Explorer. If you want, delete other conhost.exe imitations.
It is possible to run a full system scan by installing any conhost.exe virus removal tool. With the help of this, you can find the conhost.exe virus and remove it.
If the previous methods don’t work, you should try installing a full antivirus program. While it helps to delete the fake file, it also assists in setting up the PC with a scanner used to keep viruses away from the PC.
If necessary, you may take the help of a free bootable antivirus tool that lets you scan the entire PC before the operating system starts up. This method is expected to fix the virus because the process will not run during the virus scan.
Is it a legit process?
You should know that the original one is a legit process. The OS or operating system needs this, and you must not remove this. But what will you do if the process isn’t original? The process might take up much memory and CPU usage. What will you do now?
To verify the process, you should go through these steps.
- You should right-click on the process in Task Manager. Then, you need to choose the option Open file location.
- If the file is in C:\Windows\System32, you can ensure that a legitimate app runs the process.
But it may happen that the process is not in System32. If it is the case, there is a chance that a virus or malware disguises itself as a Console Windows Host process. A few viruses can keep memory usage at a high level. Hence, you need to use antivirus software to scan suspicious files and remove this.
