One thing i have noticed about all Surface tablets is that no matter what you change you lock/welcome screen to, for a short second you will see the standard circle wallpaper it came with... for glimpse of a second. Is this really a glitch that MS cannot solve. I tried many laptops that didn't have it. Maybe it's time that MS looked to the vendors for some simple learning. Update upon updates, it is still there. Am i the only one wondering about this.
