However, the limitations of Disk Management have to be stated clearly. To shrink a partition in this utility, one can only shrink from the right side. That is to say, the generated unallocated space is AFTER the partition. Nevertheless, to extend a partition in this tool, the unallocated space must adjacent to the target partition and located in the right side. Otherwise, the “Extend Volume” will grey out. To make long story short, Disk Management can’t extend boot partition if the unallocated partition is separated by other partitions.

Moreover, Disk Management cannot shrink C drive beyond half even if there is redundant space left on the partition. As a result, to manage hard drive partition more smoothly, it is better to use powerful third-party free partition resize tool.
