Windows 10: Windows 10 20H1 to address high CPU and performance issues

Microsoft is introducing a new algorithm for the Windows Search indexer that makes it more efficient in terms of overall system performance, CPU and disk usage. The changes included in Windows 10 version 2004 (20H1) could finally address the complaints of high CPU and disk usage in the OS.

Microsoft says it carried out extensive research over the last year to identify critical problems in Windows Search. The research revealed that excessive disk and CPU usage are the two main general performance issues experienced by users.

Windows Search service or search indexer powers Windows Search across all apps, File Explorer, and it roams across your PC. Microsoft uses search indexer to crawl your files, documents, pictures, videos, apps, and metadata to return results quickly when you trigger Windows Search.

Microsoft has been continuing to work on Windows Search improvements while developing new features for the OS. For example, Windows 10 May 2019 Update added ‘Enhanced Mode’ that makes it easier to expand a search index.

By default, Microsoft limits Windows Search to scan folders like document, pictures, videos, and desktop. The Enhance mode expands the coverage to include all folders except the locations used by Windows such as System32.



While Windows Search indexer is important, it causes excessive disk and processor usages. Microsoft is apparently aware of significant system slowdowns caused by Windows Search and a fix is included in the next update.

According to Microsoft, Windows 10 version 2004 comes with a new algorithm to detect excessive disk usage and other performance issues. If performance issues are detected, Windows 10 may throttle any search indexing activity to reduce possibilities of slowdowns.



Microsoft says it would stop the Windows Search indexer service when CPU usage goes above 80% and disk usage goes above 70%. The service is also disabled when gaming mode is turned on or when the device’s battery charge is less than 50%.

Microsoft says it would also continue to improve Windows 10 search in other ways and Windows Search improvements is very much an ongoing process.

You can expect your devices to run a little smoother after installing Windows 10 version 2004. According to a recent report, Microsoft has already finalized the next major release and 20H1 could be deployed as soon as April/May 2020.

Hi Steven,

Thank you for posting your query in Microsoft Community.

I understand the inconvenience you are facing. Let me help you in resolving the issue.

I would appreciate if you can provide us the following information to help us understand the issue better.

• Did you make any changes to your computer prior to this issue?
• Which anti-virus program is installed on the PC?

I would like to inform you that High CPU usage occurs for various reasons, for example: virus/malware infections, out-of-date drivers, anti-virus programs or other third-party programs, etc;

I suggest you to follow the methods below and check if that helps:

Method 1: Windows has a built-in troubleshooter to check and fix issues with system. I would suggest you to run this troubleshooter to check if the issue is with your System
Maintenance.

• Press Windows key + X on the keyboard.
• Click on Control panel.
• Type “Troubleshooting” without quotes in the Control panel
  search box.
• Click on Troubleshooting and click on View all.
• Click on System Maintenance troubleshooter and follow the on-screen instructions.

Method 2: Check if the issue resolves in
Safe Mode.

Refer this article to boot to safe mode:

Steps to reduce the CPU usage.

1-Press "Ctrl," "Shift," and "Esc" on your keyboard. This brings up the task manager without any intermediary screen.

2-Click the "Processes" button on the task manager.

3-Click the "CPU" column header until the arrow next to the label points down.

4-Right-click a program you recognize that uses a high percentage of the CPU and click "End Process." Click "End Process" to reconfirm. This eases up on the CPU's load. Use this step if you're not using a process or if the process has stopped responding. Do
not use this procedure for windows processes.

High CPU usage in Windows 10.

Hello Gred,

We realize the inconvenience you are experiencing with high CPU usage in Windows 10. We will certainly help you.

• What do you mean when you say "there are many scheduled updates that I can not see"?
• Do you mean you are not receiving Windows updates?

High CPU percentage may be due to various reasons like too many programs running in the background or a certain program is consuming high CPU usage. Let's try the below steps and check if it helps:

Step 1: Place your system in Clean boot state and find out which software or program is causing the issue:

To help troubleshoot error messages and other issues, you can start Windows by using a minimal set of drivers and startup programs. This kind of startup is known as a "clean boot." A clean boot helps eliminate software conflicts.


Refer the article below to perform clean boot:

http://support.microsoft.com/kb/929135

Note: Please refer to the section:
How to reset the computer to start as usual after troubleshooting with clean boot
of the Kb article to boot the computer in normal startup after fixing the issue.

Disclaimer: A clean boot is performed to start Windows by using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install
a program or an update or when you run a program in Windows. You may also troubleshoot or determine what conflict is causing the problem by performing a clean boot. You must log on to the computer as an administrator to be able to perform a clean boot. Your
computer may temporarily lose some functionality when you perform a clean boot. When you start the computer normally, the functionality returns. However, you may receive the original error message, or experience the original behavior if the problem still exists.
If the computer is connected to a network, network policy settings may prevent you from following these steps.

Step 2: Further I suggest you to refer the link below and check if it helps:

Let us know the status of the issue. We will be glad to assist you further.

Thank you.
