Updated April 2024: Stop error messages and fix your computer problem with this tool. Get it now at this link
There are many malicious programs that attempt to occupy high CPU usage on Windows operating systems. One such program is called “Csrss.exe”. This malware tries to use up all the CPU resources on your computer, making it impossible to run other applications. If left unchecked, this could cause serious problems for your PC.
In most cases, Csrss.exe is installed without your knowledge. When you install software, you usually agree to terms and conditions that allow the installer to make changes to your computer. However, some apps do not clearly state what actions they take.

Overview of Csrss.exe High CPU Usage
The Client/Server Runtime Service host (csrss.exe) is a Windows system process responsible for managing the client/server model used by Microsoft’s.NET Framework. The process runs under the SYSTEM account and consumes significant amounts of CPU resources.
This article outlines how you can use Process Explorer to identify processes running under the SYSTEM account and determine what each one does.
What is Csrss.exe?
Csrss.exe is a core part of the Windows operating system, which is responsible for handling critical tasks like taking control of the computer during the shutdown process. While csrss.exe does perform some important functions, it is also used by malware to take over computers.
When an application crashes or hangs – such as Microsoft Word crashing while you’re writing a document – csrss.exe will automatically restart it. This allows hackers to use the same mechanism to gain access to a locked down machine. Malware can also force csrss.exe to start up without asking for permission. If you see “csrss.exe has stopped working” error messages on your screen, try rebooting your PC.
We highly recommend that you use this tool for your error. Furthermore, this tool detects and removes common computer errors, protects you from loss of files, malware, and hardware failures, and optimizes your device for maximum performance. This software will help you fix your PC problems and prevent others from happening again:

Is Csrss.exe a Virus?
Csrss.exe is one of those programs you never really pay attention to because it just runs in the background doing what it does best – nothing. But sometimes, it can cause problems for Windows users.
The program itself doesn’t do anything malicious; it simply monitors system activity and reports information about it to Microsoft. However, there are some instances where it could become a problem. For example, if someone installs a rootkit, it could use csrss.exe to gain access to the computer without being detected. If someone tries to install a keylogger, it could use csmgr.exe to send data to the attacker. And if someone wants to steal passwords, it could use cstmr.exe to log into accounts.
So how does csrss.exe work? Well, it’s actually a part of the kernel process called Kernel Base Dump Service (Kd). This is basically a diagnostic tool that allows developers to see what’s happening inside the operating system. It provides information such as memory usage, CPU utilization, network traffic, etc.
However, it’s important to note that csrss.exes aren’t viruses; they don’t replicate themselves, nor do they infect computers. They are merely tools used by hackers and cybercriminals to perform certain tasks.
Can I Disable Csrss.exe?
Csrss.exe is one of those things you don’t want to mess with unless you know what you’re doing. If you disable csrss.exe, you might end up having to reinstall your operating system. This isn’t something you want to do without knowing how to fix it. In fact, there are many different ways to reduce CPU load, but none of them will actually prevent the process from running.
If you disable csrss, you’ll see the following error message: “The requested operation requires elevation.” You’ll notice that there are no options to elevate the program. However, you can still run the command prompt as administrator. From here, type the following command:
net start wininit
This will restart the Wininit service. After rebooting, you’ll be able to open Task Manager again and turn off csrss.
You can also use the registry editor to disable the service. Open regedit and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\. Name the key csrss and press Enter. Double-click csrss and make sure StartupType Disabled. Reboot and try turning off the service again.
How to Repair High CPU Usage with Csrss.exe on Windows 10?
CSRSS.EXEis an executable file which runs in SYSTEM account. The malware will run in the background without any notification or Warning. There are many ways to solve csrss.exe problem such as registry cleaner, anti virus software, spyware remover, etc. However, it is better to use the manual method to delete csrss.exe process because some tools might cause damage to your system.

If you want to know how to stop csrss.exe, please follow our guide. If you want to learn how to prevent csrss.exe attack, please read our article.
Solution 1: Check Csrss.exe Virus
There are many different kinds of processes called csrss.exe. Each type of process has its unique purpose. Some malware creates multiple c srss.exe files and use them to spread malicious code; others just keep one copy around. If you see multiple c srss.exes, there could be something wrong with your Windows installation. If you find that csrss.exe appears in a folder named System32, the system will work fine. However, if csrss.exe resides in some other location, the problem lies with csr ss.exe itself.
If csrss.exe exists in C:\Windows\system32, the system will function normally. But if it is located in another place, such as C:\Program Files\Microsoft Visual Studio 12.0\VC\bin\x86_amd64, then the problem lies with the executable file itself.
Solution 2: Utilize Windows Defender to Perform a Manual Virus Scan
To manually scan for virus, please follow the steps below. If you do not know how to use Windows Defender, please refer to our previous article about it.
1. Open the Start menu and type “Windows Defender”. Click on the program icon.
2. Select “Scan Now”.
3. A window will pop up, showing the status of the scan. Wait for the scan to finish.
4. After the scan finishes, you can see the detailed information about the detected threats. You can delete the detected files directly from here.
5. If there are no problems found during the manual scan, you can close the Window. Otherwise, you can continue to read the next step.
6. Right-click on the file name in the list and select “Properties”. Then, go to the Details tab. Check the box beside “Hide protected operating system components.”
Solution 3: Delete the User Profile
If you are experiencing problems with csrss.exe using too many CPU resources, it might be because of one of the following reasons:
1. A corrupted Windows profile.
2. An old version of Microsoft Internet Explorer.
3. A third-party application that runs under the name “svchost.exe”.
4. Some malware infection.
5. There could be some error messages related to the registry.
6. You might be logged into a domain account.

Frequently Asked Questions
Why Am I Observing Two Instances of CSRSS Running Simultaneously?
If you’re like me, you probably noticed that there are sometimes multiple instances of the Client Server Runtime Service (CSRSS) running at once. This is completely normal; however, you might wonder why there are multiple instances of this process running at once.
The reason you see two instances of CSRSS running at once is because the program is actually doing two different things. One instance of the program is responsible for starting up the second instance of the program. So, what does this mean? Well, let’s say you want to run another instance of the program. You could simply double-click the.exe file again, but that wouldn’t work. Instead, you’d need to start the second instance manually.
In addition to the standard version of the program, there are also several different versions of the client server runtime service. These include the 32-bit version and the 64-bit version. For example, if you open the Task Manager, you’ll see both a 32-bit version and a 64-bit version listed under the Services tab.
This article explains how to identify whether you have a legitimate copy of the program installed on your computer.
