Windows 7: Increasing size of C: boot partition?

Increasing size of C: boot partition?

In setting up my wife's computer, I allocated 30 gigs to the C: partition...probably a big mistake. I'd like to increase its size by about 100G, and I have shrunk the D: and E: partitions accordingly, using the Disk Management tool.

Now however I am stuck with two separate blocks of unallocated space, and apparently no way to expand the C: partition into that extra space. Is there any way this can be done within Win7 or do I have to seek out some additional software?
