Csrss.exe Error Fix Tutorial – What To Do If Csrss.exe Has 100% CPU Usage?

Csrss.exe

Csrss.exe is a file used by the “Microsoft Client Server Runtime Server” system – a critical piece of software which allows Windows to control many of the graphical options on your PC. Despite csrss.exe being a highly important file, many people report this either as a virus, or as an unwanted program that will continually use 100% CPU usage on your system. If you’re seeing errors or problems with this file, you can follow the steps outlined in the tutorial on this page.

What Are Csrss.exe Errors & What Causes Them?

Most people report seeing csrss.exe errors when they right-click onto a file, icon or program on the desktop and try to do something. The issue is that the user profile you’re trying to open the feature for on Windows will be unable to work correctly, leading your system to run much slower and with the problems you’re seeing.

The cause of this problem can be anything from a damaged system setting to a corrupted registry file – making your system think it’s able to run the csrss.exe file, but it cannot. To fix this problem, you need to be able to repair any of the issues that are leading the problem to show on your system – a process which can be achieved by using the steps outlined below:

How To Fix Csrss.exe Errors

Step 1 – Clean Out The Registry Of Your PC

The most important part of fixing csrss.exe errors is to make sure that your PC has all the correct settings inside the “registry”. The registry is a central storage facility for all the files, options and information that your computer requires to run, and is where your system will keep many of the important files it requires to run csrss.exe. Despite the registry being highly important, it’s often being damaged and made unreadable. To fix this, you should first download a registry cleaner and let it fix any of the problems that you may have on your PC. This will resolve the csrss.exe error for most people.

Step 2 – Clean Out Any Viruses

It’s a common problem that people will get some sort of virus or infection on their PC, which will prevent your computer from properly being able to run various important files. Despite this causing major issues, you can fix most of these issues by downloading & running a reliable anti-virus scanning application. We recommend using a program called “XoftSpy”.

Step 3 – Delete Your User Profile On Your System

The most likely reason why csrss.exe errors will be showing on your PC is because your user profile will be damaged or corrupted. To resolve this problem, you should delete the profile and then re-create it. Please be warned, however, that this process will lose your personalized settings & information – making it important that you back up any of the files properly before you attempt this. Here’s what to do:

  • Log into your system as the “administrator
  • Right-Click on “My Computer” and select “Properties
  • Inside the new menu that loads, click on the “Advanced” tab
  • In here, Select “User Profiles > Settings
  • Select your corrupted profile and delete it
  • Re-create your profile to make your PC run smoother again
