I have low space on the C: drive (C: drive is 12 GB). I hear somewhere on the net that you can actually delete the install files of Windows updates.
How can I delete them? Where are they located? Is deleting these files going to damage Windows or remove the installed security patches?

You're probably thinking about people suggesting deleting the
$NtUninstall*$subdirectories pof%SystemRoot%. These subdirectories contain the uninstall files for updates.Deleting these directories removes your ability to uninstall the updates that created them. I tend not to delete these directories because I prefer to have the flexibility to back-off an update, if need be.
In a couple dire situations I've moved these directories to another volume for "safe keeping" to free up space but I wouldn't recommend deleting them.
