when i uncheck my user pic, my name is across the left default windowblind user icon on this one.
That is not a default user icon, it is part of the user pane image in this skin.
Since this skin is set up for Vista look with user icon on right, the content margin settings are set to move user icon, when in use, into the frame for it on right.
Open the skin in SkinStudio, on left side of preview select XP Taskbar, click on user pane in preview, in Text Settings you should be able to move text by increasing the X value of Text position shift
