As stated in this answer Drush needs to find the settings.php file in order to work. My problem is that the settings.php file is indeed in the right folder (and I have navigated to the Drupal root folder before issuing the Drush commands), but it still does not work to update modules with drush. I just get the message that Command pm-update needs a higher bootstrap level to run. It even states itself that the Drupal settings file is located in sites/default/settings.php.

I have also followed the instructions in this post, with no luck.

What else can I try?

This is the error message:

C:\wamp\www>drush ups
Command pm-updatestatus needs a higher bootstrap level to run - you      [error] will need to invoke drush from a more functional Drupal environment
to run this command.
The drush command 'ups' could not be executed.                           [error]

Drush was not able to start (bootstrap) the Drupal database.             [error]
