“I want to divide my C drive into two partitions, use one partition to install programs, use another one to save some operation files. But I find that the “Shrink Volume” option grayed out at my computer, is this a error of Windows server 2016 or problem of my computer? How can I fix it and enable shrink volume?”

FAT32 volumes cannot be shrinked in disk management and if your disk is old with fat32 file system, it cannot be shrinked under Disk Management.

Solution: Shrink c fat32 drive with Partition Resizer which is a safe tool that can ensure OS safety without losing data.
