Fix System And Compressed Memory High CPU Usage In Windows 10

Suffering from 100% CPU usage by System and Compressed Memory process on windows 10 computer. The computer not running smoothly became not responding for a long time. When you check Task Manage resource usage you will notice system and compressed memory consume almost 99% CPU usage. Looking for solutions to get rid of this problem. Don’t worry Here in this post we have some working solutions to fix the system and compressed memory high CPU usage problem permanently. But Before perform solutions first understand the problem. What are the System and Compressed Memory process? Why is it running on your Windows 10 computer? Why is it using a lot of CPU resources?

Windows 10 computers system and compressed memory is a process responsible for various functions related to system and memory. This process is mostly responsible for the compression of files, folders, and the management of RAM. This is an advanced feature on Windows 10 computers to compress the pagefile.sys.  Typically, the System and Compressed Memory process only use a small number of your computer resources, including CPU, RAM, and Disk.

Also, sometimes users report when windows service (superfetch, windows update, BITS) gets corrupted, not respond then it starts to consume huge system resources like CPU, RAM, or Disk. However, if it uses too much CPU, RAM, or Disk resource, then you’ll need to diagnose and find the cause of that high computer resource usage problem. In some cases, the System and Compressed memory process can use 100% of your CPU, or RAM, and make your computer run incredibly slow, or even crash.

System and Compressed Memory High CPU Usage

After knowing what is the system and compressed memory and what job done by this service let’s follow the below steps to fix this system and compressed memory hist CPU usage problem permanently.

Note: Bellow steps are also applicable to fix System and compressed memory HIGH Disk and 100% memory usage problem. 

Scan your computer for viruses.

Start with basic Troubleshooting check your windows for virus infection. Many viruses or malicious programs can cause the System and Compressed Memory high CPU (or memory) usage problem. So, before you continue to troubleshoot the issue, first install the latest updated AntiVirus or Antimalware application and perform a full system scan. check and remove viruses or/and malicious programs that may be running on your computer. After performing a full system scan remove any virus or malware if found and restart windows. Check this time windows running normally? If still face the same issue follow below the solutions one by one.

Note: The System and Compressed Memory process can cause high CPU, RAM, or Disk usage problems. I would recommend that you try all the solutions below, one by one until you fix them.

Stop or Disable Superfetch, BITS, and Windows update

As discuss some times corrupted not responding to windows services may also cause this system and compress memory to use high CPU, Disk, and memory issues. First, try to Disable them If these services cause any issue the after disabling the service you may notice windows come to a normal state. Here follow the below steps to stop these services.

Stop / Disable Superfetch Service

First What is Superfetch? It’s a Windows service that is used to maintain & improve your Windows system performance. However, Superfetch sometimes can cause the System and Compressed Memory process 100% disk usage issue. To fix it, you need to stop the Superfetch service, or even disable it. To do so, follow the instructions below:

  1. Press Windows + R to launch the Run dialog box.
  2. Type “services.msc” without the quotes and press Enter.

  4. Double-click on it and choose “Stop“.
  5. In the “Startup type” drop-down list, select “Disabled“, then press the “Apply” button and then the “OK” button.

On the same windows look for Background Intelligent Transfer Service ( BITS )and windows update service. Double-click on it and choose “Stop“. In the “Startup type” drop-down list, select “Disabled“, then press the “Apply” button and then the “OK” button. Now after stop all three Services Now restart windows and check System And Compressed Memory High CPU Usage problem Fixed. This is the most working solution to fix the High CPU, Disk, And 100% memory usage problem on All Windows computers. After performing this solution still getting the same problem follow the next solution.

Set The pagefile.sys File Size Back to Automatic

This is the Second Best Solution to Fix System And Compressed Memory High CPU Usage ( High Disk and 100% memory Usage ) problem on Windows computers. By default, Windows will set the page file.sys file size and manage it automatically. You can also adjust it to a particular value as you want. However, doing that can lead to a few issues with memory compression, or sometimes causing 100% CPU usage, High disk usage, or 100% memory problem in Windows 10.

If you recently changed the “pagefile.sys” file size, restoring it back to the default setting will help you solve this problem. To do so, follow the instructions below:

  1. First Press Windows and then choose Settings.
  2. In the Settings window, search for “Performance” and then choose “Adjust the appearance and performance of Windows“.

  4. In the Virtual Memory window, check the “Automatically manage paging file size for all drives” box.
  5. Click the “OK” button twice and then restart your computer.
