This thread was originally started in May 2012 soon after the Three Elms PH closed and the possibility of a Tesco Express was first mooted. Since that time the store has opened, with serious concerns about customer parking and pedestrian safety by the (small and inadequate) car park entrance on top of the junction, and illustrations of certain problems and improvements made since. At the end of 2014 Tesco announced plans to open a store at the top of Peascod Street, in the old H Samuel (1888 Grade II) shop premises but subsequently this was apparently shelved and so our thread title has been adjusted to reflect the latest position. (July 2015)
This thread covers outlets in Windsor but it should be noted that there is a major Tesco store in Slough, and another Tesco Express in Datchet, so we have 'ample' Tesco outlets locally. Below is the original post from May 2012.
Sadly, the rumours were true and The Three Elms looks like this today.
