You may be unable to extend the C: partition when it is running out of space because the "Extend Volume" option is grayed out. This usually happens when the unallocated space is not directly next to the C: drive, for example when it is located after the D: partition. To solve the problem without reinstalling Windows 7, use a partition manager to move or allocate the unallocated space so it can be added to the system partition safely.
The main reason is that Windows Disk Management can extend a partition only when adjacent unallocated space is available on its right side. If the free space is separated by another partition, the process cannot be completed. Disk Management also cannot move partitions, so a dedicated partition tool is needed in this situation.

This will move the unallocated space behind the C: partition and allow you to allocate it to the partition.
4.To save changes, click "Proceed" and wait several minutes. The unallocated space will then be successfully added to the system partition.
