Csrss stands for Client Server Runtime Subsystem, it basically just creates worker threads between client requests. These files are found in the details tab of the task manager. They are integral to the operating system of your computer and should not be deleted.
The csrss files are actual windows files and don’t actually do any harm to your computer, so you should keep them. However it may be problematic when viruses like Trojan horse and malware are hidden under the guise of these files.
It does become problematic when trying to identify whether these are actual windows files or hidden viruses. Here is how you figure out whether these files are legitimate or not and how to keep your computer safe:
- Press WIN+x together, then select task manager in the menu.
- Go to the details tab, then hit C key to find the csrss.exe files faster.
- Select open file location by right clicking on csrss. Exe.
- Ensure that the file locates to Local DiskC:/ Windows/ System32.
This ensures that the csrss file is an actual windows file in your OS rather than a virus hidden in your computer.
