We just refreshed the Sample Browser to support Windows 8 Consumer Preview. You can now install and run the sample browser on Windows 8 CP or Windows Server 8 Beta.
In this update, we also fixed an issue that when the sample download fails because some paths or file names in the sample package are too long (> MAX_PATH (260) characters), the sample download status is restored to a wrong value. With this fix, the sample download status will be restored to the value before you hit the download/update button.
