HI,
There are some settings for Registration in the Woocommerce >> General Tab:
-Registration
|—Allow registration on the checkout page
|—Allow registration on the “My Account” page
|—Register using the email address for the username
And besides this controls, “User registration” is a WordPress functionality. WooCommerce uses that WP-function in order to add a new user-role as customer.
If you don’t want any users to register than you may want to look at the WordPress Main Settings
WordPress Admin >> Settings >> General
-Membership
|–Anyone can register
We have a Dante v2.12 update out to fix all the issues and recommend to upgrade to latest version .Hope it will help you .
With Best Regards
