I just came across a neat little utility called Package This that allows you to create an offline Windows Help File (.chm) from topics on MSDN.  This is a great way to get the latest SDK documentation on your local drive without having to wait for (and install)the latest refresh DVD.

The utility is available in both compiled and source, and does have a few dependicies, so make sure you read the info first.  Download Here

As a test, I created a local version of the Windows Home Server SDK docs, and it worked as promised.

Special thanks to MDodich on the WHS forums for pointhing this out!

UPDATE : Please note, the WHS team has created an addendum to the SDK that is not in this help file.  You may download it here
