Win7 license

I have a windows 7 home premium 32-bit, is it possible to use the License that came with it to install a 64 bit instead? I bought 8GB of ram & I barley learned that my computer won't utilize all 8GB unless I have a 64 bit. Yes my computer can run 64 bit, I used the Microsoft program that tells you if it can run it. But my only question is, if I can use a a license that came with a 32 bit win7 home premium to remove the OS & install a 64 win7 home premium instead.

  1. if you purchased the retail pack there should be 2 options to install 32bit and 64 bit, but if you have DSP/OEM pack it will only be 32bit

    How do I know if I have a retail pack or the DSP/OEM? Would it say on the package I bought it in or where can I see which one I have?

    IF you Go to Control Panel - System and look at the section where it has the activation status if it is an OEM product it will have OEM in the Product ID line just below the Window is activated line !

    Even if it is OEM you can use it to change to 64 bit -- The product key will work for either 32 or 64 bit installs interchangeably BUT you will need to get an install disk for the 64 bit version (the retail version comes with both disks where OEM version only includes the 1 disk --- If you have an OEM version you can get the install media iso from Digital River (which is Microsofts approved digital download source - Link to article with various links for the images

    You will need the image that matches the version you have ( ie. home premium, Ultimate, professional, etc. - but the 32 or 64 bit versions are interchangeable) - So download the correct version for the license you have and create a bootable iso image to use for installation. --- NOTE : be sure to back up anything you need before reinstalling as switching from 32 bit to 64 bit requires a clean install - meaning you have to format the HDD and thus will lose any info on that partition !!
