The System and Compressed Memory Service high CPU usage issue occurs on Windows 10 computers without an obvious reason. Up to today, I have faced this issue several times, either in clean Windows 10 installation(s) or in many Windows 10 computers and tablets such as Microsoft's Surface Books.
What is the System and Compressed Memory Service?
On previous Windows versions, when your physical memory (RAM) becomes full, Windows uses a file on your disk called "pagefile.sys" as an extra memory and stores there pages that aren't used at the time the memory becomes full. At a later time when RAM is emptied, Windows load back these pages to RAM. This feature prevents the system from running out of memory.
On Windows 10 the above feature, goes one step further, but instead of transferring the unused pages to the pagefile, Windows compress them (to make their size smaller) and continues to keep these pages in the physical memory (RAM). This service is called "System and Compressed Memory Service" and is used on Windows 10 to improve the overall computer performance.
