6 Easy Ways To Fix 100% Disk Usage By ‘System and Compressed Memory’ In Windows 10

Windows 10 comes with its own set of problems one of them is “100% disk usages by system and compressed memory”. If not 100% then it can be really high amount of disk usages. System and Compressed memory handle the different processes and memory on the Windows system.

If you are affected by high disk usages in Windows 10 then you should have these questions in mind-

What is the system and compressed memory?

How can you fix it?

We have got you covered in this tutorial.

What is The System and Compressed Memory?

It is a Windows native process that controls and monitors various functions relevant to the system and RAM operations. The process is responsible for the compression of different files and folders in your hard disk. It also manages the RAM memory for various processes and programs.

Typically, system and compressed memory should only utilize a minor part of the computer system memory. But sometimes, your PC suddenly starts to run at full force and you hear the sound coming from the CPU.

Is this problem old or a result of a virus/bug?

This problem was first reported in 2013. It was not until Windows 10 Upgrade that people actually felt the nuisance of the system and compressed memory disk usage.
This is NOT a bug and upgrading your Anti-Virus will not make a difference. It is just old Windows 10 in all its glory.

Introducing Pagefile

A feature called ‘Pagefile’ exists within Windows by default.

When you uninstalled heavy programs before in Windows XP, Windows 7, etc., the system would offload some of the least used Pagefile from your hard drive to save some space for the RAM that is already full.

When the RAM is full, fetching data takes time, hence the slowdown! The whole process is quite cumbersome, but you get the picture! As a result, the slower systems would crash/freeze frequently.

Today, these problems have been mitigated with faster & larger-sized RAMs and ROMs. Moreover, Windows 10 can automatically choose how much size should it allocate to Pagefile.

Where does Pagefile fit into the modern context?

In Windows 10, system and compressed memory high disk usage happens due to the process described above, Windows 10 limits the task of putting away unused Pagefile and stores them in the RAM instead.

This has a florid title called ‘Method & Compressed Storage Service’.

It is primarily configured in Windows 10 to enhance the system performance. Although you can change this default setting and set it to automatic to let the system choose what is best.

Fix ‘System and Compressed Memory’ 100% Disk Usage In Windows 10

There is no particular fix for the issue, you have to try these options. It may be due to corrupt system files, paging, superfetch, visual effects, and many more.

Here are some working fixes you can apply-

1. Repairing Corrupt System Files

There may be some corrupt Windows files behind high disk usages. You need to find and repair such files.

  1. Open the cmd as an administrator.
  2. Type sfc /scannow and hit enter. The system file checker would find the corrupt files and repair them.

Once the process is complete, restart your PC. SFC tool scan detects and replaces the corrupted or missing system files using the available recovery image inside Windows.

If SFC can’t repair the corrupt files that mean the replacement files inside the Windows 10 are damaged and the SFC tool won’t work.

In this case, you need to use the DISM tool (Deployment Image Servicing and Management) to scan and repair the install.wim image, after this you can use SFC tool again.

Open elevated cmd and type-

  1. DISM /Online /Cleanup-Image /CheckHealth to check the health of the local repair image.
  2. DISM /Online /Cleanup-Image /ScanHealth this command will scan the issues with the local image file.
  3. DISM /Online /Cleanup-Image /RestoreHealth The command will repair issues with the image file.

This DISM tool will connect to the Windows update server to download and replace corrupt or missing files in the local recovery image. Which is install.wim. Make sure you are connected to the internet and Windows update it to turn ON.

Once the image repair is complete, run the SFC /SCAANNOW command again. Since the DISM tool repair only the image file not Windows 10.

If you want to automate the above process then you can download a third-party tool called Reimage Plus.

Download the program REIMAGE PLUS, and run it to check for corrupt and missing files. If found any, this software will repair them automatically.

Now, head to Task Manager (Ctrl+Alt+Del) and see if the system and compressed memory usage is still on the high side. If so, then move to the Second Method.

2. Let Windows Choose The Paging File Size For All Drives

The size of the Pagefile can be reset by a user. By default, Windows decides this on its own. If you have ever configured this part, then you need to set it back to Automatic mode.

1. In the Start menu, click Settings and search for Performance & then click on Adjust the appearance and performance of Windows.

2. A new window with Performance Options will now pop open. Head over to Advanced.
