I have only seldom access to windows, but this command should work,
shouldn't it? Can you verify, that either of the commands:
%sudo% %params% "cmd.exe /k type %newcontent% >%myfile%"
and
%sudo% %params% "cmd.exe /c type %myfile% >%newcontent%"

works? (Please replace %sudo% by runas, %params" by you parameters for
runas and %myfile% and %newcontent% by the name of the file as given in
the commandline?

BTW: It might be better to solve this issue off list.

Christian
