Can the public beta of Windows 7 be installed in different PC's such as desktop and laptop? Or should you download a version for each? Thanks for the info and keep up the Extraordinary work!

There is only one version for this sort of computer type. You can install the Beta of Windows 7 either on a PC and on a laptop.Peter Forster, MVP Virtual Machine, Austria

Thank u very much for confirming me.I know that all os r bootable after burnt to a dvd or cd or while they camebut I'm quite confused after reading vista service pack 1 needed for upgradation.I forgottenforsome moment thatupgradation meanswith saving previous data shifted to new os.Thank u again!!!regardsJagadish: )

you can install on a laptop or a desktop, you can use the product key three time (according to microsoft) I've used it nth times on different computers, it still gets accepted and activated (Me thinks Microsoft only let go of 10 product keys for all beta users)....could be wrong though.
