Although you can get unallocated space by shrinking partition in Disk Management on Windows 7, it is recommended to delete the partition behind C drive because adjacent unallocated space is needed in order to extend C partition. Besides, "Extend Volume" is available unless there is continuous space behind this partition. Otherwise, you cannot extend any partition.

Since deletion will erase all data on the partition, you had better move all important data to another place before deleting the partition.

You can only create unallocated space on the same hard disk. If there are more than one hard drives installed on your computer, you cannot increase unallocated space from one hard drive to extend another hard drive unless you have a third-party tool to help you.
