In Windows 10, we have added a new concept in the Memory Manager called a compression store, which is an in-memory collection of compressed pages. This means that when Memory Manager feels memory pressure, it will compress unused pages instead of writing them to disk. This reduces the amount of memory used per process, allowing Windows 10 to maintain more applications in physical memory at a time. This also helps provide better responsiveness across Windows 10. The compression store lives in the System process’s working set. Since the system process holds the store in memory, its working set grows larger exactly when memory is being made available for other processes. This is visible in Task Manager and the reason the System process appears to be consuming more memory than previous releases.
在更新说明中g说（大致意思）：
压缩存储存在于系统工作集中。因为系统进程在内存中承载了（压缩）存储，因此当系统为其他进程留出内存时，工作集（占用的内存）会增大。这个变化会在任务管理器中可以观察到，这也是系统进程看起来比之前的版本占用了更多的空间的原因。
