Fix Windows Vista Help and Support problem in RTM
Info from Kristan Kenney If you have been getting the dreaded “Internet Explorer cannot download / from help” error message when attempting to open Help and Support in Windows Vista, try this fix. It re-associates the .xml file type with its default settings. Once you’ve merged this into the registry, re-launch Help and Support and it should work. You can download the fix at http://www.chris123nt.com/guides/RTM_Fixes/Fix_Help_and_Support.zip. By the way, My friends and I did not get that problem after the installation of Vista RTM and Office 07 RTM. It’s really strange!
