People used Process Monitor to scan Origins behaviour and posted pictures of the program accessing files of their tax management program

and their cell phone manager

now obviously its scanning directories, but to look for games when the only "games" available on origin are from EA I find it hard to believe it would need to do such a deep recursive scan, but regardless I find it quite amusing that this program can pretty much hook into everything - read config files and who knows what else, it's shit like this on why I don't buy many games and the primary reason I refuse to install origin.
