In this article, you will learn some basics about computer memory, the signs of high memory and some proven solutions for you to solve the most common Windows 10 high memory usage problems.

Some Knowlege about High Memory Usage

Computer memory is one of the most important physical devices of a computer to store information temporarily or permanently. It includes RAM (random access memory), ROM (read-only memory), and Cache (click computer booting to know the relationship between RAM and ROM). It enables computer CPU to access instructions and data quickly.

The memory is used to temporarily store the operational data of CPU and the data exchanged with an external memory (such as a hard disk). In other words, CPU can transfer the data that needs to be operated into the memory for operation when the computer is running and transmit the result out when the operation is completed.

Furthermore, the program installed on hard drive disk is also loaded into memory for running. That means the main memory is a major factor in determining computer performance and operation stability.

How To Check Windows 10 High Memory Usage Problem?

Windows 10 high memory usage is highly related to RAM and virtual memory. Although memory is closely connected with CPU and hard drive, the high memory usage problem is different than the problems of high CPU usage and high disk usage.

If the computer encounters a high memory usage problem, it will freeze, this situation happens often when a large game is running. Sometimes, you will see “Your computer is low on memory” error message windows.

In addition, computer users can also diagnose and determine high memory usage issues in Windows 10 on Task Manager. Please follow the steps: rightclick the taskbar and select Task Manager.

First of all, you should know there are common causes of the high CPU/RAM/memory usage problems on Windows 10.

  • Running multiple programs at the same time.

  • Defective program design.

  • Startup programs.

  • Registry hack.

  • Insufficient disk capacity.

  • Virus or antivirus.

How To Fix Windows 10 High Memory Usage issue?

Fix 1: Close Some Programs

If the high memory usage is caused by many programs which are running simultaneously, users could try to solve the problem by closing some unnecessary programs. Or if a program takes up too much memory, you can also end this program to fix the issue. Open Task Manager and then right click the application you want to end up under Processes and choose End task.

Fix 2: Disable Superfetch Service

Superfetch service, especially designed for traditional hard drive disk, is booted by default. It improves computer performance by only allowing the memory to load a fraction of the data needed to run common programs at fast speed.

If your computer disk is hard drive disk, you should not disable Superfetch service, even though it may cause high memory usage on Windows 10. However, if your computer disk is SSD, this service should be disabled. (Follow the instruction to disable Superfetch service. )

Press “Windows + R” keys, and type “services.msc” to open Services window, scroll down to select Superfetch, and then rightclick on it, at last, select Stop to disable it.

Fix 2: Turn Off Startup Programs

Some programs run automatically when the computer starts up. If you don’t need these programs to run at startup, you can disable them.

Load up your Task Manager and access the startup programs tab by typing in task manager in the Windows search menu. Next, rightclick any programs that you don’t want to run at startup, at last, select Disable.

Fix 3: Increase Virtual Memory

Virtual memory can make a portion of disk space serve as memory to relieve memory stress. On hard disk, the virtual memory is actually a big file named PageFile.sys.

How to set virtual memory in Windows 10? Follow the instructions as follows.

Step 1: Find virtual memory and click Change.

  • Open File Explorer and rightclick This PC, and then select Properties.

  • Next, select Advanced system settings in the pop-up window.

  • And then click Settings in Performance box under Advanced page of System Properties

  • Navigate to Advanced page in the pop-up Performance Options window, at last, click Change in Virtual memory box.

Step 2: Cancel virtual memory on partition C.

  • First of all, Uncheck Automatically manage paging file size for all drives.

  • Then select partition C and then check No paging file, and then click Set to save it.

  • After that, click Yes in the pop-up warning window.

Step 3: Set Suitable Virtual Memory On The Non-System Partition.

  • Select a non-system partition, and then check Custom size.

  • Set a same value in Initial size and Maximum size to avoid system frequently requesting page files of different sizes, which can reduce the consume of system resource and boost operating efficiency.

  • Then click Set and OK to save.

Fix 4: Set Registry Hack

Please follow the following instructions.

Step 1:

Press “Windows + R” and then type “regedit” to open Registry Editor.

Step 2:

Then Navigate to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Session Manager > Memory Management.

Step 3:

Find ClearPageFileAtShutDown, rightclick it to modify its value to 1, then click OK.

Step 4:

At last, restart your computer to boot up the Registry Hack setting.

Fix 5: Defragment Hard Drives

Defragmenting hard drives is a good way to save some memory space. Users can use Disk Defragmenter to do defragmentation.

Open File Explorer and select Partition C, and then click Manage on the toolbar and click Optimize. At last, select Partition C and click Optimize.

Additionally, computer users should delete unnecessary files on Partition C. The Space Analyazer feature of MiniTool Partition Wizard is recommended to do this operation. You can also use this feature to display hidden files for you to delete them. Please follow the tutorial.

Step 1:

Download MiniTool Partition Wizard and launch it. And then click Space Analyzer on the toolbar.

Step 2:

Select Partition C, then click Scan. After scanning process is completed, select unnecessary files and right click them to delete.

Note: “.sys” files must not be deleted, otherwise your computer can’t boot.

Fix 6: Methods That Are Suitable For Software Problems

Windows 10 memory leak

In certain situations, the Windows 10 high memory usage is caused by memory leak, which is caused by defective software design.Memory leak has great influence on computer server where programs will run for a long time. It will make memory space smaller and smaller and even result in downtime.

Windows 10 memory leaks will consume nearly all the memory space. Although rebooting the computer can solve this problem temporarily, when the software runs again, the problem will reoccur.

Fix 7: Virus Or Antivirus

Virus can also cause Windows 10 high memory usage problem. Users can run trustworthy antivirus programs, or they can run the built-in Windows Defender if they don’t install other antivirus program. Here is a guide to use Windows Defender.

Step 1: Find Windows Defender.

  • Click Start button and select Settings.

  • Next, select Security & Update.

Step 2: Run Windows Defender.

  • Click Windows Defender and Open Windows Defender Security Center.

  • Select Virus & threat protection and then click Quick scan.

There is one more thing, a lot of users have reported that certain antivirus programs, including Windows Defender may cause Windows 10 high memory usage. In this case, you are suggested to end the process of antivirus programs in Task Manger.

Fix 8: Adjust For best performance

Step 1:

Open File Explorer, right click This PC, then choose Properties.

Step 2:

Click Advanced system settings, then click Settings in Performance box.

Step 3:

Check Adjust for best performance and click Apply. At last, click OK.

Fix 9: Reinstall Windows 10

Some users also report that Windows 10 high memory usage only occurs when they leave the computer alone for about 30-45 minutes. This problem may occur after upgrading to Windows 10. They have tried the above methods, but still have no luck to solve the problem. Eventually they have to reinstall Windows 10 or reset PC.

When users decide to reinstall Windows 10 or reset PC, making a data backup is highly recommended. If the reinstallation and reset have accidentally caused data loss, MiniTool Partition Wizard can help you effectively recover them.

Fix 10: Increase Physical Memory

If the physical memory is very small, users may consider adding a memory bank. Open File Explorer and then right click This PC to select Properties, then you can check memory size.

4G memory can satisfy the needs for most users. However, if your want to use computer to run large programs or to play games like H1Z1, at least 8G memory is needed. If you want to add memory, please note that the memory type must be the same to avoid incompatibility issue.
