So I checked the python.exe*32 (the only python that is running) in the
taskmanager (after booting and starting the wxGUI). And although
GRASS_PYTHON is set in the environmental variables to C:\Python27\python.exe,
the python which is used is still the GRASS-Python in
the path C:\Programm Files(x64)\GRASS 6.4.1\extrabin\python.exe
So what causes this? How can I proceed? What should I check?
PYTHONHOME is NOT set!
Any suggestion what causes the problem?

How did you set GRASS_PYTHON?
AFAIK, it's set in %GISBASE%\etc\env.bat; this will override any
global setting.
