Some off the settings in my S:.vimrc work defenitly like "syntax off" / "syntax on" or "set number" / "set nonumber". But as I said "colorscheme blue" or "colo blue" worked not.
When I put the line "autocmd GUIEnter * colo blue" into my S:.vimrc it works a treat and the colosheme in the GUI is changed as expected. So thanks very much for your help.
I did some google search for the command "autocmd GUIEnter" you told me and
this came up.
It looks like this behaviour was also seen with vim 7.3 for some Windows users and they speculate that some plugin is messing it up.
I also tried the secound workaround that I saw on stackoverflow which also worked.
