Reasons C Drive Extension Doesn’t Work With Windows 10

Even though so many people have encountered this problem, not many know the why extending C drive in Windows 10 is greyed out. There are some reasons why that is so. The first most probable reason why the extension is greyed out is that your PC does not have unallocated space. There is no way you can carry out a drive extension without the having an unallocated space. Also, in the case that such space is available, the problem may be that it is not near the C drive you want to extend. The second reason is that the inbuilt Windows Disk Management you are trying to use does not work with on a FAT partition. If your C drive is a FAT partition, the inbuilt utility would not work as it works with only NTFS partition. The third reason is that the C drive partition is the one holding your boot files. If that is the case, then the process would not work.
