So if I understand you correctly I can do as a 6th step the removing of the python2.5 which comes with winGRASS. What do you mean exactly with removing, deleting the python2.5 folder in programms/grass6.4.1/? 

Which references have to be removed? There were no environemental variables created during the winGRASS installation pointing to Python25 (the winGRASS python).
