Ultimate Category Excluder for WordPress
Ultimate Category Excluder (UCE) is a WordPress plugin that allows you to quickly and easily exclude categories from your front page, archives, feeds, and searches. Just select which categories you want to be excluded and UCE does all the work for you!
You can download this plugin from the WordPress plugin repository.
This plugin has been particularly handy with categories that house useful content, but content that I don't want to have appear on the homepage or in my feeds. For example, I have a number of definitions for technical terms and while these can help users reading my content, there's no need to have a definition appear on my homepage or get pushed out via my RSS feeds.
