The only difference it should make is to enable the computer to log onto a
domain type network and a few other features not available to the
non-business license like the fax capabilities. It should NOT delete any
programs or data files but as with any change to the operating system you
should have a full and complete backup of data files and preferably an image
of the functioning computer before the upgrade.

See
http://www.microsoft.com/windows/win...s/default.aspx
for the differences between the versions.
