IIS7.x: Webdav Troubleshooting

When you're troubleshooting webdav problems in IIS 7.0 and think that everything should be working (but its not), consider uninstalling webdav completely, rebooting, downloading the most current installer package from https://www.iis.net/download/webdav (even if you think you already have the latest bits), and reinstalling webdav. This isn't the answer to every webdav problem but it seems to me to allow good progress for the stranger webdav cases.
