Sit tight.
You might want to look at the AUTOEXEC.BAT file.
The following commands:
SET USERNAME=JOHN ;Your Name Here
SET PASSWORD=DOE ;Your Password Here
might do what you want.
As for setting up Microsoft programs, you might look into creating a
macro to setup the program login and password. You could call the MS program from within the AUTOEXEC.BAT (perhaps on a delay command) to open the program and run the macro.
Just an idea. I have not tried it myself.
Good Luck...
