Two worst offenders are:
- Antivirus: Just hogs memory, the scan runs "throughout the day" and I've had to resort to using scripts to shut the thing down just so my code will compile.
- Other annoying features: Lets make you stare at a dayglow green wallpaper and give you no way to change it to something that doesn't offend your eyes, lets place a bunch of icons on your dock and desktop that you can't get rid of, just bookmarks to common apps. Lets also make a popup show up on your laptop every day to remind you that you need to upgrade to OneDrive but forget to give me the permission to actually upgrade so this message repeats itself and fails every time..
