Note 76: Fredrik works [at the time of my writing, this is not true any more] for CodeGear in Europe. In his his blog you can find a lot about Delphi and Vista and (in particular) a post about “UAC and Signed Applications” at http://blogs.codegear.com/fhaglund/archive/2007/06/08/35729.aspx.
This was the original link, but the content is not there any more. All you can find is a link to the new location in the new Fredrik's blog, but the specific pages seems to be missing there as well. Anyway, you can find (on the new blog) several posts about UAC in Vista from the Delphi perspective. Maybe Fredrik can help me find the new URL...
This blog post is part of my "113 Delphi 2007 Handbook Notes" blogging project, to promote my new Delphi book.
