in short, no.
Because of the fact that when you install something like ms office, it:
writes registry entries
creates symbolic links
installs new files in the windows dir.
you will have to do seperat installs.
also, say you have a drive partitioned into three partitions.
everytime you open a data file, you need to access all three partitions:
the windows partition to find out which program opens the file
the programs partition to open the program that opens the file
the data partition for the actual file itself.
A harddrive head can only read/write to one place at any given time, so this would drastically slow down your computer.
On the flipside, if you had three different physical drives, and decided to do something like this, it may, actually speed up your system (depending on a couple of factors)
