Welcome aboard, redhawk87
You are right ... windows 7 is not that big ! There are some ways to ger some extra space in the C drive. Hard Disk Space - Free Up and Recover
On the other hand, if you really want to extend the C drive, it is also possible. For better suggestions, can you please upload a screenshot of the full screen disk management window ? (Click the start button, at the bottom there is a blank bar saying "search program and files". Write "Disk management" there, and click the resulting link [create and format hard disk partitions]). Screenshots and Files - Upload and Post in Seven Forums
If there is the D drive just at the right side of the C drive, you can use the method Partition or Volume - Extend
, but at the same time, the Option three
of the tutorial Partition Wizard : Use the Bootable CD
works for the extension at the either side.
