What is conhost.exe?
Conhost.exe is a process under Windows Vista and Windows Seven that handles the functioning of the cmd command with respect to the security protocols. Now with the advent of Windows Vista introduced in the market there were many significant changes made to the core Microsoft engine. Conhost.exe is one of such changes and it led to many alternate performances such as inappropriate drag and drop function to the Command prompt.
Now previously all the responsibilities entrusted to this new process was handled by csrss.exe (Client Server Runtime Process), a system process powered by Admin privileges. Now you would be interested to know why this process was created. The reason is very simple yet precise. Earlier interactions between processes or applications running under different LEVELS were not allowed to intercommunicate so as to exchange files or data. Microsoft considered this as a problem for inter-dependencies of applications and this led to the innovation of Conhost.exe process.
Is Conhost.exe a virus?
This process is a very genuine process and is of no worry if it is running from its system defined root directory. But other than this if there is another location from where it is being run or called, specially from the Temp file or My documents or Users directory, it is a threat to your system.

Conhost.exe – Windows Vista: Windows Seven
Now this is a very tricky thing Microsoft did with this process. While it was first introduced under Vista so as to manage the security aspect of the console window, it led to some bugs and errors in the long run. But with every loophole being surfaced, Microsoft quickly decided to run this process under Csrss.exe under Windows Seven. This change in authority led to minimal errors or I would rather say zero error of this process. Now if you watch with process explorer you will find this process running under Csrss.exe whereas under Vista it was an independent process.
If you have this error message on your screen you belong to the least category of people who ever encounter problem form this process. As I have mentioned earlier this is a Zero error process (I meant it after it was reprogrammed under win 7), the solution is also a direct one.
Usually such errors occur after you have newly installed any new application on your system. The first step would be to uninstall the newly installed application and see if the error persists or perishes. Now if the error still pops up, there is a higher chance of another malicious program using this process under it.
Browse to the system root directory to see if the file is there. If it is then you have a higher recovery chances.
- Go to tools — folder options —- show hidden files and folders — Show hidden operating system files and folders – Ok.
- Now search for conhost.exe on your whole computer. If more than one shows up delete all other than the one inside the root directory.
- Update your antivirus and run a full scan of your system.
If the problem still persists try scanning all your programs with official Microsoft scanner. You can download it from here.
Conhost.exe multiple instances
If there are multiple instances of this process running under task manager, Do not panic as this is totally natural. This generally happens when the console host is unable to handle a particular request and it just tries again and again generating multiple instances. To overcome it just open the task manager, right click the conhost.exe process and select end process tree.
