Windows 7 - 32 and 64 bit upgrade question

According to the MS website, Windows 7 Home Premium upgrade includes both 32 and 64 bit versions. Does anybody know if they are selectable on the upgrade? I will be running WinXP Home, which is a 32 bit OS, but I'll want to install the 64 bit version of Win 7. Is this possible, or will the upgrader be limited to the bitrate of what is already on the HDD?

Thanks

  1. Best answer
    if it follows other versions of windows then there would be no way to upgrade from a 32-bit OS to a 64-bit OS without doing a fresh install.
  2. According to what I read on the website, a fresh install, going from XP to 7, is required from the upgrade.

    "Running Earlier Versions?
    If you have Windows XP or Windows 2000, you can purchase Windows 7 Upgrade versions. But you must back up your files, clean install, and reinstall your applications."

    For a Vista installation: An "Upgrade" is limited to the bitrate already installed. Should you decide to do a clean/complete installation to the same partition - 7 will detect the existing version, and should put your data into a folder it will create called "WINDOWS_OLD".


    For XP - Back up your data and do a clean installation for either version of Win7.
