Laptop constantly on high memory usage. How to fix

Hi Arya,

Welcome to Microsoft Community.

I'm Hahn and I'm here to help you with your concern.

According to the screenshot you provided, 93% memory usage is very high.

There are many reasons for this problem, and we suggest you can follow the following method to troubleshoot it step by step.

Method 1: Increase Virtual Memory

Virtual memory is a computer system memory management technology that allows a portion of disk space to be used as memory to relieve memory pressure. You can manually increase virtual memory to solve the problem of high memory usage in Windows 11.

1. Press Windows Key + R together to open the Run window, type sysdm.cpl and press Enter to open System Properties.
2. Under the Advanced tab, click Settings.
3. In the pop-up window, select Advanced > Change.
4. Uncheck Automatically manage paging file size for all drives and select partition C (system partition), then check No paging file and click Set.
5. Click Yes in the pop-up window, and finally click OK.
6. If you also need to increase the virtual memory of non-system disk (take F drive as an example), you can check Custom Size, and then set the values of Initial size and Maximum size to 2048MB, and finally click Set and OK.

Notes:

Setting the Initial size and Maximum size values to the same size will prevent the system from frequently requesting paging files of different sizes that consume system resources for no reason, and it will improve operational efficiency.

You can adjust the Initial size and Maximum size values to 1.5 or 2 times the physical memory, which can be found under the Performance option of Task Manager.

It is recommended that you restart your computer to allow the changes to the Initial size and Maximum size to take effect.

Method 2: Disable Superfetch Service

The Superfetch service can help programs create caches, which serve to make full use of free memory and quickly load a portion of the data pieces needed to run commonly used programs, thus improving computer performance.

Therefore, the Superfetch service may also cause high memory usage problems on solid state drives (if your computer is using a mechanical drive, you don't need to disable the Superfetch service), and you can solve the high memory usage problem by disabling the Superfetch service.

1. Open the Run window, type services.mscand press Enter to open the Services window.
2. Find the Superfetch service and right-click Stop.

Method 3: Defragment the Hard Disk

Defragmenting your hard drive can help your computer run more efficiently, here are the detailed steps.

1. Press Win+R to open the Run window,type dfrgui and press Enter to open the Optimize Drives.
2. Click on the drive that needs to be defragmented and then clickOptimize.

Method 4: Set ClearPageFileAtShutdown to Free up Virtual Memory

Modify this registry entry to delete the page file at shutdown to free up virtual memory. You can follow the steps below to set this up.

1. Press Win+R to open the Run window, type regeditand press Enter to open the Registry Editor.
2. Navigate to the path below.  Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management.
3. Find ClearPageFileAtShutdownand double click to open it, thenchange the value to 1, click OK. Restart your computer to enable the Registry Hack setting.

Method 5: Disable Chrome Preload Option

In order to make the web browsing process smoother, Chrome has added a page preload option. It preloads the next web page that the user is going to view and shows the web page at a faster speed when the next page is actually opened.

Although this option enhances the user experience, it will also cause high memory usage in Windows 11, you can choose to disable this option.

1. Click the Settings button in the upper right corner, and then select Settings.
2. In the left menu, select Privacy and security, then selectCookies and other site dataon the right.
3. Find the Preload pages for faster browsing and searching option and close the button on the right.

Method 6: Disable NDU in the Registry

Disabling NDU files in the Registry is also a solution for high memory usage in Windows 10, but this method may affect the use of your Internet. If none of the above methods can solve your problem, you may try this method.

1. Type regedit in the Run window and press Enter to open the Registry Editor.
2. Navigate to the path below. HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Ndu.
3. Find the Start file in the Ndu file, double click to open this file and change the value to 4, then click OK.

Please restart your computer to see if the problem is solved. If you find that your computer's Internet connection is disabled, we recommend you perform the above steps again and change the value back to 2.

If there is anything not clear, please do not hesitate to let me know.

Your Sincerely
