If I download the Windows 7 Beta iso (which is quite a big file to me , as you would expect) and the beta updates updates will i need to re-download the iso or will it be like vista and have a thing pop up saying Windows Update? I really don t want to download it every week. and say NOOT updates but things like it upgrades from build 7000 to 7500 or something. Will i need to redownload then?

To upgrade it to a newer build you will need to reinstall it but to install regular updates you don t. You can just use Windows Update. You re welcome. Be sure to make me have the best answer! :)
