MS Paint

If you would like to keep your sanity, I would recommend not using this app, otherwise you risk getting annoyed into insanity.
Many fonts broken, it changes to segoe ui, cant be bold, and it crashes without reason, so its forever gone as it doesnt autosave. Makes people wanting to break things out of rage.
