    Vista 32 to 8 x64


    Hi all!
    I've currently a laptop with Vista 32 bit ( regularly activated ).
    My CPU supports 64 bit instruction format so I want to increase RAM and install Windows 8 x64.

    Is it possible??
    There is a way to do this with only an Upgrade disc?

    Thanks in advance for all the answers

    Welcome to EightForums.

    To upgrade x32 to x64, you need to do a clean install.

    No need to reinstall old Windows install.

    Clean the HD Drive, using Step one in this tutorial:
    SSD / HDD : Optimize for Windows Reinstallation - Windows 7 Forums

    & than Reboot PC to install.

    So I don't need a "full" Windows 8 PRO but only the 40$ downloaded 64 bit Upgrade?

    You can do a clean install, but you need to delete the old Windows install.
