Hi Preston, this is not a permissions issue, it is caused by Windows limited partitioning capabilities . . .
From looking at your screenshot, do you want to extend your C drive into that Unallocated space?
If so, Windows will refuse to do that, because there are other partitions between the two, you need to use a 3rd party utility to do that
Download the free version of AOMEI partition assistant, the free version is fully featured, easy to use and will allow you to extend your C drive into the unallocated space, by automaticallt moving those other partition to the right . . .
