The Windows 10 Anniversary Update (1607) introduced a new annoyance for me, moving the Action Center / Notification to the right of the clock in the system tray. Maybe I’ve just used Windows for too long and am so used to the clock been in the same place, however this minor change really started to annoy me after a couple of days, especially as i’ve never had any use for the action center anyway.
Thankfully Windows 10 has some options hidden away that allow users to turn system icons on and off.
