If you've ever had to do the "rename .Xap to .Zip" routine while doing Silverlight development, then you'll enjoy this fix. The entry also sets the MIME type of .Xaps to "application/x-silverlight-app", so it relates to my earlier post about the MIME type, too.
I've been using this on my Windows Vista and Windows Server 2008 workstation, but have not tried it on XP.
