When using XAMPP and importing a Drupal website, I ran across an issue. The clean URLs weren’t working for some reason.
Load your Apache httpd.conf file and search for AllowOverride None. Replace it with AllowOverride All.
All should work nicely now!
This fix isn’t specific to XAMPP, mind you.
It should also work on similar setups, such as with WAMP and MAMP.
If you still have issues after this, then check your HTACCESS file (though the default Drupal 7 one should be fine) and your vhost file.
