From http://msdn.microsoft.com/msdnmag/chm/ , select the 2007 Issues and the December issue, English version. The link gives me a 404 File or Directory not found error. The full link to the chm file is: http://download.microsoft.com/download/3/a/7/3a7fa450-1f33-41f7-9e6d-3aa95b5a6aea/MSDNMagazineDecember2007en-us.chm This looks similar to the November link, so I suspect the actual file name has a typo.
