"Process" roughly means "a program that's running at the moment". A strange one would be something like bird_tweet.exe or evil_virus.com. Gentoo doesn't have random tweeting bird problems, but it does require knowledge of things like recognizing a strange process. I doubt you'd like it.

Sorry, I should've recommended rebooting Windows. Rebooting Windows solves the majority of problems, and reinstalling it solves the rest. ("Problems" in this case means annoyances which CAN be solved while still deciding to run Windows instead of something else.)
