C'est l'exploit que cet homme a fait. Il passe d'upgrade en upgrade par toutes les versions de windows (sauf ME) et se paye le luxe de démontrer qu'entre chaques upgrades, les parametres et applications sont conservées !!

Commentaire de l'auteur:

An experiment to see the effects of installing every major upgrade version of windows, in order, on the same machine.

FAQ

1) Why Didn't you Install ME?

Since Windows ME cannot be upgraded to 2000, I chose to install 2000 straight from 98 as it was chronologically the next release. I might do an
"alternate history" version to see what going from 98 to ME to XP looks
like.

2) Did Doom 2 and Monkey Island work in Windows 7?

Yes. Sorry I didn't point that out explicitly in the video.

3) Can you do the same thing with Mac OS?

I don't know enough about Mac OS to be able to say, and I would not be
the best person to do that experiment as I have never been a Mac user.

4) Where are you from?

Scotland.

5) What's that beeping noise in the background?

My smoke detector - its battery is flat :)
