[Fix] Net Routine Optimization Service CPU (100% Working)

This problem normally occurs randomly, although it can sometimes occur after such an upgrade to the Microsoft.NET Framework has been installed. Using Task Manager, mscorsvw.exe is just the executable file of the process, and this will be listed within that name or even as Runtime Optimization Service, depending on the version of Windows you are running. It runs seldom, and it is a service that optimizes the.NET Framework, and this, in turn, ensures that applications and software that rely on this now run more quickly as a result of the optimization.

But users have complained that this optimization requires an excessive amount of time & requires a significant amount of CPU resources every time this is executed, which they believe is incorrect. It also lasts for several days at a time. To attempt to remedy this issue, please follow the steps outlined below. 

Reasons Behind the .NET Runtime Optimization Service High CPU Error

The official response is that the procedure requires recompilation of its library and that it can only be done whenever the system is not in use or is otherwise idle. The procedure, according to Microsoft, will not take over than a few minutes to complete. However, that isn’t the situation, and customers are forced to wait for over a week before seeing any results. Consider some of the reasons behind this: 

It is normally slow to respond, so you can start to speed the process up by issuing specific commands on the computer.

Malware may be running in your system that has either hidden it as the program or that the service has indeed been compromised with malware. Try to run malware scanning on your computer. The AntiMalware service may be demanding a significant amount of resources in certain circumstances, particularly when malware is present. 

It’s possible that the service has been corrupted, and then you should consider rebooting it.

Fixing Methods of ‘Net Routine Optimization Service CPU’ Issue

Method 1: Optimize the Process

This is not necessary to terminate this procedure immediately because it will benefit your system as well as the way that applications and video games are run on your pc. Although, there are several ways to speed up the procedure, like running this handy command or executing a script to achieve the same result. This should allow the operation to make using more CPU cores, which should allow it to complete its tasks in a more timely manner.

Step 1: Alternatively, you simply navigate for “Command Prompt” either directly in the Start button or by selecting the search bar immediately adjacent to it. You have to right-click on the search result that matches the best and pick the “Run as administrator” option from the menu that displays.

If you are using an earlier edition of Windows, you may open up the Run box by pressing the Windows Key + R keyboard shortcut together. To start Command Prompt as an administrator, enter “cmd” into the box and press the Ctrl + Shift + Enter altogether. 

Step 2: Using your command prompt, copy-paste the lines listed below, and hit the Enter button after typing every command. Pick a command that corresponds to your computer system from the first two options (the first command is for 32-bit and the second command is for 64-bit).

cd c:\Windows\Microsoft.NET\Framework\v4.0.30319 

cd c:\Windows\Microsoft.NET\Framework64\v4.0.30319

Determine whether or not the.NET Runtime Optimization Service’s CPU use has returned to the stable.  

An alternate would be to use the official Microsoft program, which should perform the very same results whether you are confused about executing the command line on your own or whether you’re using an earlier edition of a Windows XP.

Method 2: Scan Your PC for Malware

Even though this sounds over the top, malware infections are one of the leading causes of this problem and you must check your computer for malware. Malicious programs would want to get a hold of your resources and they usually name their processes as something which would resemble files on your computer.

It may seem difficult, but malware infestations are by far the most common reason for this issue, and you must scan your system for malware. Malicious applications still want to enter your pc or laptop, thus they name the tasks in a way that is similar to the names of documents on your system.

Malwarebytes Anti-Malware is now a fantastic anti-malware solution that is available in a free version. You can easily download it from the company’s website.

Launch Malwarebytes by searching for it in the Start button or even on your Home pc, then select the Scan option from the application’s main screen. 

The utility will most likely start an upgrade process to refresh its malware database before continuing with the scan. Please wait to complete the process, which may take some time. If malware is found on your system, make sure it is removed or blocked.

Once the scanning procedure is completed, reboot your pc to check if you’re still experiencing problems with the.NET Runtime Optimization Service. 

Using additional security scanners is recommended whether you are familiar with the type of virus that has infected your machine (ransomware, junkware, etc.). Furthermore, a particular scanner may not be able to detect and remove all sorts of malware, so I recommend that you experiment with a variety of different scanners.

Method 3: Restart your Service

Restoring the program will also restart the entire process, however, this will be much more efficient this time around, specifically if there was an error that caused it to fail in the first place, as described above.  

Launch the Run application by pressing the Windows Key + R keyboard shortcut on your computer simultaneously. Then, type “services. msc” in the run dialogue box and hit OK to display the Services.msc window.

Once you hit on the Start button, you may find the warning message:

“Windows could not start the service on Local Computer. Error 1079: The account specified for this service differs from the account specified for other services running in the same process.”

If this occurs, follow the steps outlined below to resolve the error.

Method 4: Run a Clean Boot

In some situations, a third-party application may be responsible for excessive CPU utilization as a result of the required optimization. Because of this, you should do a clean boot to determine even if there isn’t any third-party impact on the program.


Fixing this error is very simple. Follow the steps properly to solve the error message.
