The virtual PC is free, but the OS is not!

Go to http://portableapps.com/ which is a great set of the basics, and
has links to all sorts of individual projects as well to portable-ize
various apps. Good info on how it's done. There is also a great program
called "Total Uninstaller" that does a great job of tracking what
registry entries are made and where every file goes when installing or
running (takes snapshots and isn't quick, but you run it once). There
are files that get installed in the program directory's tree, the
common  Windows areas, and entries to the registry. Many apps will just
recreate the entries if they don't exist, others will barf instead.

It is possible to take the common files and put them with the program
exe and it will find them by default (you can run it from a single
directory) - the only problem being that if an incompatible version is
on the host machine AND in use at the time you run it, it won't load
yours. I've found very few conflicts 'portable-izing' 3GB worth of apps
I use so far though.

If the registry is a big problem for MPLAB, then using Total
Uninstaller, you would know its entries and could make a small VB app to
write the entries at startup and zero them out before ejecting the USB
stick.
