unsecurom is old as hell anyway, probably wouldn't work....
and the question you asked you could answer yourself by simply trying the german crack (after backing up the files it changes).....
and 'NT Based environment' = win2k upwards, so yes, xp is included, however there was a patch for unsecurom to make it work in nt based os'
but it still probably wont do what u need, due to its age...
