i have windows vista home premium.
so would it then work to "upgrade" my system without harming the structurse and without having to reinstall anything? is that correct?
There have been many, many posts, and I agree, that the upgrade you want is not the best way to go. Both from the standpoint of a quality OS and time taken to upgrade, it is better to do a clean install.
If you use Windows Easy Transfer, and back up all your files, you will be much happier with a clean install.
