I'm using taskbar eliminator to remove my windows 7 taskbar as I prefer my mix of rainmeter and rocketdock, however it doesn't really work all that reliably.
The taskbar appears when windows starts and I have to manually run taskbar eliminator again to remove it. The taskbar occasionally pops up of its own accord again later regardless.
The program is set to run on startup and while I am using Soluto, Taskbar Eliminator is set to stay in boot. I have two screens and manage them with DisplayFusion
