well according to the threads on that forum, and the amount of stuff i tried to do with the registry editing has lead me to believe that once youve written a code segment like that, and save it as a .reg it instantly becomes like a executable piece of code that imports all the libarys in question into the registery and the very important one in that file seems to be one called WAVEMAPPER, which ive come accross in programming it seems to be a handle for wav sounds which ive noticed windows likes to use, and apparently the new version of adobe flash sometimes acidently removes it from the registry and the fix simply puts it back. but im not that sure as i said its merely the conclusion ive come to.
windows nt though i could go on about for some time, i wont go into to much detail but around the time windows 98 was being written (i think) which was posibly around 1980 all the windows programs where based on DOS, which was a bit...crap, caused crashes and stuff, so microsoft got together with IBM to write OS 2, which was like a new operating system and then a bunch of s**** happened and microsoft as usual came out on top, it fell out with IBM and took OS 2 all for itself and renamed it to NT that stands for New technology, so then microsoft based some operating systems on NT and some on dos...98, and i think ME. then 2000 was meant to be an accumaltion of both, built on NT but with emulators and stuff for dos. then finally XP was the new soley NT based operating system, which is why it doesnt support some things that 2000 will as it technically shouldnt have the emulators. so whereas windows was really based on dos, windows nt is based on the os 2, which really should belong to IBM but microsoft are evil backstabbing b*******...even there DOS was stolen lol....2bh i wonder if they ever programmed anything....(sorry msft pleas employ me

lol)
and thats pretty much the story i can remember from the long *** assingment i had to do on it, im not sure if its all correct though!
XP is something like NT version 5, it does tell you somewhere. the stupid thing though is that if you notice 2000 start up with the message built on NT technology so technically there saying built on new technology technogy.
hope that helps to some extent, research the history of NT, os2 or windows os's if you really want to know more
