I too typically start Windows 8 in desktop mode, but I did it through the little app you mentioned from Stardock called Start8 (more details at http://stardock.com/products/start8/). For only $4.99, I can avoid all the the task scheduling issues and go right to the desktop. I've also been using their Fences (for many versions) and have recently started also using their Decor8, which lets me customize the lock screen, Start screen, as well as desktop. Cheap, and it does the trick...;-)

Thanks,
Richard
