[SOLVED] 100% Disk Usage by System and Compressed Memory

Process and Compressed Memory is a Windows 10 feature responsible for memory compression (also referred to as RAM compression and memory compression). This feature basically utilizes data compression to reduce the size or number of paging request to and from the auxiliary storage. In short, this feature is designed to take less amount of disk space and memory but in this case the System and Compressed Memory process start using 100% Disk and Memory, causing the affected  PC to become slow.

In Windows 10, a compressions store is added to the concept of Memory Manager, which is an in-memory collection of compressed pages. So whenever the memory starts to fill up, the System and Compressed Memory process will compress the unused pages instead of writing them to the disk. The benefit of this is the amount of memory used per process is reduced, which allows Windows 10 to maintain more programs or apps in physical memory.

The problem appears to be incorrect Virtual Memory settings. Someone changed the paging file size from automatic to a particular value, virus or malware, Google Chrome or Skype, corrupt system files etc. So without wasting any time let’s see how to actually Fix 100% Disk Usage by System and Compressed Memory with the help of below-listed troubleshooting guide.
