For one of my sites, I haven't done them all, I just clicked on widget and then delete on the right col meta file and that did it. John

Humm! I'll have to check my sites. Tnx. Shawn! John

Great Info Shawn. Sometimes meta is very useless :(

Thanks for the training. Another one checked off.

It definetely gives a more professional look to the website, and I really like them to be as clean as posible, since the meta box doesn't have utility for customers it's highly recommended to remove it.
Thank you for this tutorial.
