well my Unregistered friend I am wandering why do you think is imposible to have windows vista with an old pc like mine? I must tell you that I have forgoten to tell in my first post that I used Vlite (is a program to custumize the windows vista installation) with this program you can remove programs that you do not need and stuff like that, I did not remove much because I wanted to leave it almost complete, the one of the few things I change was the minimum ram required from 512 MB to 256 MB and then removed READYBOOST from the installation, this two things combined is what will let you install VISTA with 128mb of RAM and even lower if you dare, the rest is up to you, but remember you can custumize and remove all the programs you want but if you do not do this things (lowering the minimum RAM required and removing READYBOOST) you won´t be able to install vista in an old pc like mine!!! try it if you like it, using microsoft virtual pc 2004 or 2007 just don´t tell the program you are about to install VISTA, when ask by the virtual PC what operating system you are about to install just put XP and that´s it....
