Plus fresh installs are so nice and clean.
People think I am crazy when I tell them if they buy a Windows PC like a HP to wipe it and install a regular Windows version to rid of all the crap that comes preinstalled.
:\ Then later I get asked all these questions, now I just say, "I use Linux, I don't touch Windows."
I do the same thing, bloatware sucks.
I would switch to a Linux main, but I'm impatient for the most part and don't feel like taking the time to do stuff in linux that I can do faster in Windows.
Basically boils down to it's what I'm used to and I don't feel like switching everything (not to mention there's a few bits of software that don't like to run even in wine).
