there's a program called TweakPower. it let's you set the transparency degree of the taskbar. you can set it to 0 with it and the taskbar's gone. the taskbar stays removed even if the program is closed so you might wanna give it a try. the program is in german, so here's how to manage it: after you started it click on "windows" on the left side, then on "desktopdarstellung". in the mainwindow click on "effekte" and move the slidebar to the left. the effect will appear immediately
