For the sake of security, turn updates back on. You can clear out the Windows Update cache either by using the script linked below:

Or by manually deleting all files under the following folders on your C drive:
C:\Windows\SoftwareDistribution\DataStore
C:\Windows\SoftwareDistribution\Download
I assume the reason you are not installing updates right now is because of this drive space problem?
Run WinDirStat and let it scan your C drive. It will show you were all of the data on the drive is located. Once you know where it is, that should give you an pretty quick indication of why it is there and what you can do with it.
