vista upgrade from 32-bit to 64-bit

    Question

  • I've confirmed that my motherboard can hand vists 64-bit.  I currently am running Vista Home Premium, 32-bit.  If I upgrade to Vista Ultimate will this give me Vists 64-bit and can it recognize 8GB of RAM?  Is there any other issue or precaution Ineed to take before upgrading?

    Thanks

    We can’t upgrade from Windows Vista 32-bit version to 64-bit version directly, clean install is required. Please refer to the following KB article that is very detailed about this topic:

     

    (KB932795) Installation choices for 64-bit consumer versions of Windows Vista

    http://support.microsoft.com/default.aspx?scid=kb;EN-US;932795

     

    All editions of Windows Vista 64-bit versions can support 8GB RAM, more information is include in:

     

    64-bit Editions of Windows Vista

    http://www.microsoft.com/windows/products/windowsvista/editions/64bit.mspx

     

    The section named Installing a 64-bit version of Windows Vista on computer that is running a 32-bit version of Windows Vista may be more helpful on such an issue.

     

    Please note, the drivers designed for Windows Vista 32-bit version may not work in 64-bit system, so do some applications compatible with 32-bit system. Please ensure that you have the drivers for 32-bit Windows Vista, and the applications critical to your business and life can run correctly on 64-bit Windows Vista.
