I am currently testing D8 in Windows8 and it begins to fail after install. I am posting here because I think it is related. Let me know if I should create a new issue.
Basically once Drupal8 is installed all it does is give these Apache errors when visiting any path in Drupal.
[Tue Feb 26 14:29:43 2013] [error] [client ::1] File does not exist: D:/wamp/www/drupal/user
However, if I change the URL to localhost:8888/drupal/index.php/user then everything works (somewhat) fine.
BTW, I am installing in a sub-directory (not using web root dir or v-host)
Apache Version : 2.2.22
PHP Version : 5.4.3
OS : Windows 8
WampServer 2.2
