Interesting article here. As a builder I do not have a problem with bloatware but I bought a laptop last year and was quite taken aback by the amount of rubbish that came installed. Yes you can remove these programs but if you are a PC noobie then this is not really an option.
We use to have a local computer repair person, who use to reformat quite a number of problematic machines. That not only removed any bloat-ware or add-ons, but about everything else, and all for £60 an hour.
