Windows 8 Developer Preview and AD CS / PKI: Cannot Get a Certificate from Web
If you are using Windows Developer Preview and have difficulty obtaining or downloading a certificate using Internet Explorer 10 (IE 10), try using compatibility mode. Turning on Compatibility View is the same in IE10 as in IE9, so you can follow the instructions at "Why do some web pages look incorrect in Internet Explorer 9?" to make the chage. This tip was added to the Windows Developer Preview release notes as well.
