Hate is too Sterling for these gripes, but this is relatively the best fit:
Windows 10, useful for some games with friends, because of the “nudges” to change my behavior, like asking if I really want to keep using that program, the magic-fingers messages on installation (suggesting I just blindly trust), and the difficulty to install without an online account, among other things. I can’t replace it yet, but the day will come, one way or another.
