Doug,

            Now I'll do technical hair splitting, but it's not trivial.  What 
you say, "You need to install those programs," is frequently simply not true, 
and that's more the case for a number of older Windows programs that were never 
"installed" in the full meaning of that term in the first place.

            Installation on any Windows system requires the involvement of 
changes to the registry if one is using the term "install" in the way Microsoft 
has used it.  You can still see this dichotomy in NVDA itself:  there is an 
installed version, which involves changes to the registry (and sometimes 
running components as services that can be started before any single user logs 
in - e.g., screen readers that operate on the log in screen) and a portable 
version which makes none.  Someone else pointed out earlier that they put the 
installed and portable versions of NVDA on their machine in case an upgrade 
makes it impossible to start the installed version they still have the portable 
one, though resident on their hard drive rather than a USB drive, available as 
backup.  So long as the system boots into Windows a portable/stand alone 
program can generally run whether a number of installed programs can or not.

            I've been doing simple copying of Microsoft Photo Editor for 
decades now because it can be run as a stand alone program with no installation 
required.

            Based on what Doug has described it seems more likely than not that 
this was a collection of stand alone programs that did not require 
installation.  Of course, if any were not, then what you've said stands for 
that select group.  I just can't see how he could have copied stuff off an XP 
machine to an external drive and trigger those programs in the way he describes 
if they were not "portable"/stand alone programs as opposed to installed ones.
