Just to clarify, add VBO, create a view page that lists products, add the Commerce Product Bulk Operation view field, and choose the modify entity values (there may actually be a status option - if so just use that) and select the Status field to be modified. Save the view, go to the page, hit the global check box at the top - a message will show asking if you want to select all product, hit modify values, select the status change, and go.
