It is a little more difficult when there is no unallocated space in Windows 7. You can delete the partition behind C drive to create an adjacent unallocated volume and then follow the steps above to increase size of C drive on Windows 7.

Tip:

1. 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. When you shrink a partition under Disk Management, the unallocated you get is not contiguous to C drive.

2. Since deletion will erase all data on the partition, you had better move all important data to another place before deleting the partition.
3. You can only create unallocated space on the same hard disk. If there is more than one hard drive installed on your computer, you cannot squeeze unallocated space from one hard drive to extend another hard drive.
