The first pictures is Regedit when i launch it in the 32bits prefix and the second is Regedit in 64bits Prefix. I launch 2 regedit command, one in every prefix. If you see the first picture (with one problem), you can notice that the police size for "Registre" "Edition" "Affichage" "Favoris" "Aide" is biggest than the second pictures. This is my problem.
