In order to test different case-studies in the book, I tried to allocate
softwares to different users to advoid conflict. However, the profiles of
ALL users including administrator reside in one directory (Documents and
Settings). And some softwares will not function  inside a directory which
has name with spaces. Win2k also does not allow me to rename the folder.

I am pretty new with this OS and ask for your help. Many thanks.
