For Windows7 or Windows2008R2 or above, when the notebook is idle, the system will automatically trim it to maintain its own performance. If you want to optimize, it will be idle for an hour or two. If it is Samsung, Intel can optimize it with its own optimization software. If you want to optimize, ensure 4k alignment and ACHI mode. Then close superfetch, restore the system, and disable defragmentation. If the memory is large enough, you can turn off the virtual memory.
