Write an article of removing the pre-installed software that come with new PC

Your job is to write a practical, straightforward article about software that comes pre-installed with most new Windows PC's. These are usually called with names such as crapware, bloatware or just pre-installed software. The article should be about: 1) What is crapware 2) Why PC makers install crapware 3) What are some of the most common crapware (give out examples but use wording such as "some people consider X, Z and Y as crapware", not "X, Z and Y is crapware") 4) How to remove crapware The emphasis should be on the fourth item. As a solution for the problem of removing crapware, your job is to introduce a freeware program called Decrap, which is designed to remove all the pre-installed software and other junk from computers. It can also be used to clean old computers but it's mainly targeted for new computers. Use a minimum of 250 words. Only bid if you are an experienced article writer.
