It is recommended that you do not end this process right away as it really helps your computer and the way all applications and software work.
However, there are many ways to speed up the process, simply by running some useful commands or by executing the official script that hosts a windows script from a windows script file to get the same result. This allows the process to use more CPU resource cores, which can speed up the execution process.
The steps are below:
1. Open the start menu and type and search. “ Command Prompt” or tap the search button next to it. Right click on the first result that appears at the top.
2. Click “Run as administrator”from the drop-down list.

8. Before proceeding with the other steps, check that the option in the Startup type menu in the service properties window is set to Automatic.
9. You may be prompted with several dialog boxes on the screen when changing the startup type. Confirm them all so that the service runs smoothly.
4. Perform a clean boot
In some cases, a third-party application can be the cause of high CPU usage due to necessary optimizations. Therefore, this solution is to apply for a clean boot to scan and check for third-party impact on the service.
Running a clean boot helps to check if the CPU usage is as high as it used to be.
1. In the search bar next to the Windows start icon, type and run “msconfig“
2. The system configuration window will open. Click on the Services tab.
3. Check the “Hide all Microsoft services”box at the bottom of the window. In this case, only third-party services will remain in the list.
4. Now click “Disable All”to disable them all.

FAQ
What is the Runtime Optimization Service. NET?
.NET is the runtime and runtime for working with common language applications. In other words, it can be said to help applications originally written in C#, VB, and F#, such as the Windows Power shell or Visual Studio, work. not written in “machine code”; they are written in a “common intermediate language”that needs to be compiled into machine code at runtime to make it easier for a computer to understand. If the optimization service does this ahead of time, your applications may skip the compilation process (JIT) step and start the process faster than expected.
What’s happened. NET? Is it a library, compiler, framework or runtime?
.NET is a virtual machine platform developed and written by Microsoft. It has a useful feature and a complete standard library that allows the user to use it to build most business related desktop and web applications.
What are runtime services in. NET?
.NET provides a runtime environment known as the Common Language Runtime. It runs the code and offers services that make the development process easier for users. Compilers and tools provide much of the functionality of the common language runtime and allow users to write code that benefits endlessly from this managed runtime.
Is the runtime. Net Core is never optimized for non-server applications?
Universal Windows apps use the. net core, which is already optimized for non-server applications. Also, there really is nothing like “optimizing the runtime for servers”.
