Windows 10: Utilizing unallocated space Drive C

Good Day! What can I do to utilize the unallocated space in Drive C? I have recently downgraded my Windows 11 OS to Windows 10 due to activation. During Windows 10 installation, I deleted some partition to the Drive C to utilize the whole disk but I didn't see the 770MB partitioned drive. I cannot extend nor shrink the volume of the Drive C itself and the unallocated space. 770MB is quite a big storage having a 512gb SSD.

Unallocated Space to C Drive

Hi Travis,

It appears that a disk partition was created but was never assigned its allocation. Assuming there are no files stored in the unallocated partition, perform these steps to combine it with your C: drive:

• In Disk Management, right-click on (C which appears next to the
  Unallocated partition.
  
• Select Extend.

Let us know if you're able to combine the spaces after following the steps above.

Regards.

 

adding unallocated disk space to drive C:

How can I add the unallocated disk space to drive C:\ when the unallocated space is not adjacent to the C:\

partitions are on the drive: such as Drives: E, F, G, H

drive F:\ has been shrunk and I would like to add the unallocated space to the C:\

however, windows will not let me expand the C: drive or move the unallocated space to Drive C:\

I am trying to do this because Windows has run out of space on Drive C:\ and I am now having a hard time printing, saving, etc.
