Thanks Guillermo for the insight, the changes to httpd.conf is what I needed to configure a root directory. However, it still doesn't bring up the install wizard from URL http://servername/moodle01. If I navigate to this URL, it just shows the directory contents; it doesn't invoke index.php from D:\moodleroot\moodle01\server\moodle.
Windows installation seems different; it doesn't just work like others here are saying it should. To get http://servername/moodle01 to bring up the install wizard, I had to move the "..\moodle01\server\moodle" folder contents to D:\moodleroot\moodle01. This seems kinda messy and there must be a better way. But it works.
