[Fix] System and Compressed Memory High CPU, RAM & Disk Usage

System and Compressed Memory High CPU, Memory RAM and Disk Usage? Learn here how to fix it with simple methods on Windows 10.

Today I will address a concern that some Windows 10 users have when they monitor the use of RAM in their system. This is the high CPU, memory or disk usage that sometimes shows the System and Compressed Memory process.

System and Compressed Memory?

Why is this happening, and what can you do to fix it? In this article, I will explain, but first of all it is necessary to understand why the high CPU usage of the System and Compressed Memory process isn’t a bad thing, but on the contrary, it is a “symptom” of an improvement that has incorporated Windows 10 and that allows a better performance of your computer.

It may sound like a joke for some, but the fact that the Windows 10 System and Compressed Memory process can take up to 4GB of RAM (or even more) isn’t an error, but something positive if you compare it to how RAM was managed in previous Windows versions.

Better Performance

In Windows 8 and earlier it happened that when the RAM to use was exhausted, the system automatically moved the memory used by the apps at rest to the paging file, which served as virtual memory housed in the hard disk.

However, since the reading speed of the files on the hard disk is much, much slower than that offered by the RAM, this caused that the use of the applications hosted in the paging file also became slower.

In Windows 10 the paging file still exists, but before using it, the system seeks to implement a better solution to compress the RAM used by the less used apps.

In this case, the performance is also lower than if the RAM were used in the usual way (since to use the apps it is necessary to execute decompression processes), but higher than that obtained using the paging file on the hard disk.

The System and Compressed Memory process is the one that Windows 10 uses to store all the compressed memory of low-use apps. That’s why this process can consume several GB of RAM, according to what the task manager shows.

By using so much RAM, it is just optimizing the use of the limited memory you have to improve the performance of applications.

But if you want to stop this service or disable it to recover your lost CPU, Disk or RAM usage, you can follow these methods.

How to Disable System and Compressed Memory

If the problem is persistent and Windows updates don’t solve it, you can disable its operation. Who is responsible for the control of compressed memory is ntoskrnl.exe and runs a service called Superfetch.

You can see your status in the Task Manager in the Services tab.

If you want to disable it temporarily, click with the right mouse button on it and click on Stop.

However, this will only stop you during this session. When you restart the computer, it will be activated again.

If you want it not to do it until you say otherwise, you will have to disable it from Services, for that follow these steps:

1. Press the key combination Winkey + R and type the command: services.msc
2. Press Enter and once in the Services window, find the service named: Superfecth
3. Right click on it and select Disabled under the startup type box.

If you want to re-enable it, you must return to this Services window and select Automatic.

Wrapping Up

System and Compressed Memory is a useful service that optimizes your memory ram on your Windows 10. But if you want to disable it to fix a high CPU or disk usage issue, now you can do it easily following the steps mentioned above.
