We make a comprehensive study on the string winding corrections tosupergravity solutions in double field theory (DFT). We find five-brane andwave solutions of diverse codimensions in which the winding coordinates arenaturally included. We discuss a physical interpretation of the windingcoordinate dependence. The analysis based on the geometric structures behindthe solutions leads to an interpretation of the winding dependence as stringworldsheet instanton corrections. We also give a brief discussion on theorigins of these winding corrections in gauged linear sigma model. Our analysisreveals that for every supergravity solution, one has DFT solutions thatinclude string winding corrections.
