Fix System And Compressed Memory High CPU Usage In Windows 10

Suffering with 100% CPU usage by System and Compressed Memory process on windows 10 computer. Computer not running smoothly became not responding for 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 this post we have some working solutions to fix system and compressed memory high CPU usage problem permanently. But Before perform solutions first understand the problem. What is 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 a advanced feature on windows 10 computers to compress the pagefile.sys.  Typically, the System and Compressed Memory process only uses a small number of your computer resources, including CPU, RAM, and Disk.
