The Windows built-in tool will not let you shrink the disk as there are system files, which you need to seek the help of third-party software. EaseUS Partition Master is the expert in coping with the inability to shrink volume issue. Its "Resize/Move" tool allows users to extend, shrink, and remove partitions easily.
