Is there a way to uncheck a "x" category of all posts in wordpress, without entering a post at a time and unchecking the category?

Uncheck all posts that contain an "x" category using the following query:
DELETE FROM 'wp_term_relationships' WHERE 'term_taxonomy_id' = id_categoria

Mass set Categories
It has this plugin that adds and removes bulk categories.
It presents all the posts at once, you will be marking and unchecking the ones you want.
There's also a idea for something similar to be implemented in Wordpress.

The most logical thing is to do this with Bulk Edit in WordPress, as commented in Ricardo's answer . But I have seen that the Mass Set Categories plugin is made up of a single file; but the code seemed confusing and out of date, so I did a quick upgrade.
Basically, it is an interface showing all the posts and with checkboxes listing the categories. The main functions are get_posts , get_categories and wp_set_post_categories .
I added an option in the first post that copies the checkbox value to all other posts to be able to check / uncheck in bulk
