#YouKnowWhatGripesMyAss? (apologies/thanks to @Yuriel for the tag)
Applications that add desktop shortcuts to the desktop by default and without asking.
I actually spent time curating the look of my desktop and I don't need a disorganised slew of random icons mucking it up, thank you very much.
Note: anyone recommending Linux in response to this will be muted or blocked.
Note 2: Yes I know I can hide icons, that's not the point.
