Buckingham Palace's spokesperson referred to her as Lady Davina Lewis in his confirmation of the divorce (link in message #136), and I am not sure she would be able to revert to Windsor even if she wished to. King George V's proclamation of 1917 said:
Now, therefore, We, out of Our Royal Will and Authority, do hereby declare and announce that as from the date of this Our Royal Proclamation Our House and Family shall be styled and known as the House and Family of Windsor, and that all the descendants in the male line of Our said Grandmother Queen Victoria who are subjects of these Realms, other than female descendants who may marry or may have married, shall bear the said Name of Windsor:
Lady Davina is included in "female descendants who may marry or may have married" (she has married, even if she has now divorced) in "the male line of Our said Grandmother Queen Victoria", so the conventional understanding is that she is not allowed to "bear the said Name of Windsor". Queen Elizabeth II, also a female descendant in the male line of Queen Victoria who had married, needed to issue a royal proclamation to allow herself to bear the name of Windsor.
