How do I turn off caching in IIS7?

Click on the server name then go to output caching.

Then simply either tick the prevent all caching or untick user-mode caching and it should stop IIS from keeping a cache of the pages.

Next time you do a full refresh, it should get the files from the hard drive and not the cache/memory
