One of the main culprits behind a slow computer system is resource hogging. When a specific program or piece of software is using up all of your CPU resources, your computer is unable khổng lồ process other applications. This will cause the computer lớn slow down, freeze, và even crash. While the .NET runtime optimization service typically does not cause high CPU usage, if it is corrupted or runs too slowly during the optimization period, it may use up 90-100% of your CPU on Windows 10 machines. If you find this happening, we have 4 solutions khổng lồ fix the issue.

What Is the .NET Runtime Optimization Service và Why Is It Important?

The .NET runtime optimization service, also known as mscorsvw.exe, is a core component of Windows 10 machines. It is used khổng lồ optimize your machine by pre-compiling .NET assemblies in the background while your computer sits idle. The reason why the .NET framework is used for software, programs, và applications, is because it contains native image generator technology, which is what allows applications and software lớn launch quickly. Without the optimization by the .NET runtime optimization service, your applications would be slow to launch. 


While you may be tempted lớn disable or end this task from the task manager, do not vày this as the hogging of your CPU resources is only temporary. If this is a recurring problem for you, there are some reliable methods that can tốc độ up the .NET runtime optimization service & ensure your computer isn’t suffering from a malware infection.

What Causes .NET Runtime Optimization Service khổng lồ Have sầu High CPU Usage?

The .Net runtime optimization service was programmed to recompile the .NET framework libraries over a span of 5-10-minutes and is only supposed to run when the computer is idle. In many cases, users report that this is not the case and here are some causes as to why.

The optimization service is running too slow, causing it to lớn hit well beyond those 5-10-minutes of operation time.The service has become corrupted, either by malware or has been damaged in some way.The optimization service that you see listed in your task manager is actually malware running under the disguise of this service.

Luckily, there are ways to lớn giảm giá with malware and any of the fixes below should solve your problem.

4 Solutions to Fix the “.NET Runtime Optimization Service” High CPU Usage Issue.

1. Run a Malware Scan to lớn Eliminate Possible Infection.

The first solution is lớn run a malware scan to lớn see if there is any type of infection or virut on your computer that could lead to the .NET runtime optimization service to lớn use a high amount of processing power. While we bởi recommend that you run a scan using your own antivi khuẩn software, sometimes malware can be disguised as regular files on your computer, causing antivirut software to lớn miss it. With this said, we also recommover running a program that is designed specifically lớn find và fix malware. A fantastic option for this is Malwarebytes. Here are the steps needed khổng lồ run a malware scan using Malwarebytes as the example.

Download and launch Malwarebytes on the computer.Clichồng on the “full scan” option.Wait for the scan khổng lồ complete.If malware is detected, select it from the danh mục and quarantine it which will remove sầu it.Restart your computer lớn see if the high CPU usage still exists with the .NET runtime optimization service.

Please keep in mind that not all malware can be detected with just one program, so running several scans with different threat levels may be required.

2. Speed Up và Optimize Your .NET Runtime Optimization Service Using the Command Prompt Tool.

The .NET runtime optimization service was designed to run using only one CPU core, but with how advanced our computer processing units are now-a-days, we can have sầu the application use multiple cores to lớn run faster. In order to bởi vì this, you will need to lớn use the command prompt tool that is built inkhổng lồ Windows 10 and you will need to know if you are running a 32-bit or a 64-bit operating system.

To find out if you are running 32-bit or 64-bit, open up your “tệp tin explorer” and right-cliông chồng on “My PC” or “My computer” and choose properties. Look under the “system type” khổng lồ see what type of system you have.In your start menu, tìm kiếm “commvà prompt” to lớn find the tool. When it pops up in your thực đơn, right-cliông xã on it and tell it lớn “run as administrator”.Enter in “cd C:WindowsMicrosoft.NETFrameworkv4.0.30319” if you have a 32-bit system và hit enter OR, enter “cd c:WindowsMicrosoft.NETFramework64v4.0.30319” & hit enter if you have sầu a 64-bit operating system và processor.Next, enter in “ngen.exe cộ executequeueditems” as the second commvà and hit enter.Wait a minute or two & then cthua trận your command prompt and open up your task manager lớn see if the issue has been resolved.

If you are running an older version of Windows và you’ve sầu run inlớn the same problem with the .NET runtime optimization service, you can use the official Microsoft script that does the same thing as the commands above sầu. This script is found here on this GitHub page and will require you to use the “save as link” on the “raw” script. The tệp tin type should be a Windows script host. You will need lớn download it and then double cliông xã and hit “execute” to lớn run it.

3. Restart the .NET Runtime Optimization Service.

You can always try restarting the service to see if it completes its process in a quicker manner the second time through. Here is how to lớn vì chưng this.


Right-clichồng on your Windows start menu & choose “run” from the danh sách or search “run” in the search bar. You can also use the Windows key on your keyboard and tap “R” lớn get it to pop open.The “run dialogue” box will open up. Type in services.msc inkhổng lồ the box & hit enter.An interface will appear. Scroll down and find the NVIDIA Telemetry Container và right-cliông chồng on it. Choose the “restart” option.Right-clichồng on the NVIDIA Telemetry Container again và choose the “properties” option.If the service is already started, choose the “stop” option. Run it again by hitting the “start” button.In the properties window, set the Telemetry Container to startup automatically.Apply the change and then hit “Ok”.

Exit and open up the task manager to lớn check to lớn see if the high CPU usage has gone bachồng khổng lồ normal for the .NET runtime optimization service process

Please note: This only works if you are running a dedicated NVIDIA powered graphics card.

4. Perkhung a Clean Boot of Your System.

It may be possible that a third-các buổi tiệc nhỏ application that you are running is causing the .NET runtime optimization service lớn run a high CPU usage. To find out if this is the case, run a clean boot of your system, so that you are only running Windows services and the default programs that are needed for your computer khổng lồ function.

Bring up the “run dialogue” box again (see solution three).Type in msconfig inkhổng lồ the box & hit okay.A configuration window will pop up. Choose the services tab at the top, checkmark the “hide all Microsoft services” box and select the disable all button. Hit okay.This will prompt you lớn restart the computer. Choose the option khổng lồ restart at a later time. Bring up the “run dialogue” box again và type in msconfig and hit okay.When the configuration box opens up again, choose the “startup” tab at the top and choose the “open task manager” from the danh mục. Look at the last field available called “startup impact” và disable any from the danh mục that are labeled as high impact. To disable, right-cliông chồng on each one that is high impact và choose disable. Reboot your computer in clean boot mode lớn see if the problem still persists. If it does not, you can re-enable any of tasks that were previously labeled as high impact by following the steps above & choosing enable. This will allow them to automatically startup on reboot.

If none of the above fixes help, you can always temporarily disable the .NET runtime optimization service, but this will vì harm to your NET Framework, which may require you khổng lồ complete repairs on it. It is not recommended that you disable the service for this reason as the NET Framework is required khổng lồ run a lot of mặc định programs on your Windows system.
