Upgrading windows 7 from 32 bit to 64 bit

I'm running windows 7 32 bit but I want to upgrade to 64 bit. Will this cost me anything or is my product key still valid for 64bit windows 7? Also where can I find the install files for free to make a usb install drive?
 

Question Info


Last updated March 28, 2020 Views 37,306 Applies to:

The Windows 7 product key will activate both 32 and 64Bit versions, so that is not an issue. However since your key was already activated, you may need to activate by phone this time around (see the end of my response).

Upgrading from a 32Bit to 64Bit version requires a "Custom" / Clean install of Windows. So backup you documents to external media (USB Drive) and be prepared to re-install your applications, so locate the installation media and associated product keys.

For the 64Bit installation see the following (Steps 1, 2 and 4 for a USB installation):

1) Download the appropriate Windows 7 .ISO file which includes Service Pack 1
(Note: must match what your product key version is for)


How to find out if I have a 32 or 64Bit version of Windows installed on my computer:
http://windows.microsoft.com/en-us/windows7/find-out-32-or-64-bit


Windows 7 Home Premium 32Bit:  http://msft.digitalrivercontent.net/win/X17-58996.iso
    SHA1 Hash value: 6071b4553fcf0ea53d589a846b5ae76743dd68fc
Windows 7 Home Premium 64Bit:  http://msft.digitalrivercontent.net/win/X17-58997.iso
    SHA1 Hash value: 6c9058389c1e2e5122b7c933275f963edf1c07b9


Windows 7 Professional 32Bit: http://msft.digitalrivercontent.net/win/X17-59183.iso
    SHA1 Hash value: d89937df3a9bc2ec1a1486195fd308cd3dade928
Windows 7 Professional 64Bit: http://msft.digitalrivercontent.net/win/X17-59186.iso
    SHA1 Hash value: 0bcfc54019ea175b1ee51f6d2b207a3d14dd2b58


Windows 7 Ultimate 32Bit: http://msft.digitalrivercontent.net/win/X17-59463.iso
    SHA1 Hash value: 65fce0f445d9bf7e78e43f17e441e08c63722657
Windows 7 Ultimate 64Bit: http://msft.digitalrivercontent.net/win/X17-59465.iso
    SHA1 Hash value: 36ae90defbad9d9539e649b193ae573b77a71c83

2) After downloading the correct .iso file install HashCalc and validate the SHA1 hash value
is correct.
HashCalc: http://www.slavasoft.com/hashcalc/index.htm
(note: If the download is not corrupt, the value HashCalc returns will match the SHA1 value I posted)


a) Launch HashCalc and navigate to the location of the .iso file you downloaded.
(The default download location is: C:\Users\User account name\Downloads)
b) Remove all check marks from the list of HashCalc options except for SHA1.
c) Click the ‘Calculate’ button and wait for the SHA1 string of letters and number to be displayed.


3) Next use ImgBurn (or Gear ISO) to create a bootable DVD.
Choose the “Custom Installation (advanced)” option and remove the check mark(s)
to eliminate unwanted options.


ImgBurn - In addition to supporting the creation of Cds/DVDs from .ISO files,
it supports a wide range of other image file formats, and it's free.

Burning ISO Images with ImgBurn article: http://neosmart.net/wiki/display/G/Burning+ISO+Images+with+ImgBurn
(The steps are the same for Windows 7 or Windows 8), except you are not creating a Repair disc but a full installation DVD)


Note: Always use high quality DVD+R media and the slowest burn speed (4x or 6x) if offered a choice.

Depends how you got the original installation and what you were licensed for by whomever sold it to you as well as whether or not the system you have will run a 64-bit operating system.

As for getting the ISO - depends on a couple of factors.  Assuming ENGLISH as the language though:

... match the edition you have installed now (Home, Professional, Ultimate.)  Use this to make your media:

The product key used to activate Windows 7 32 bit can also be used to activate the 64 bit version. You will likely need to reactivate by telephone though.

You will have to do a clean installation, there is no in place upgrade path from Windows 7 32 Bit to 64 bit.

Using the Windows 7 64 bit disk, install the Windows 7 Windows Easy Transfer Utility from the DVD (To find it, just navigate to x:\support\migwiz, 'x:' represents the name of your disk drive. In this folder, you will see a collection of files, the important one you need to look for and double click is 'migsetup'.) , run it and create a WET file (Windows Easy Transfer file), if you have an external hard disk, you can have it stored there so you can access it later when you do a clean install of Windows 7 64 bit disk.

Once you have done that, simply do a clean install of Windows 7 64 bit disk. In Windows 7 64 bit disk, launch Windows Easy Transfer, follow the on screen wizard, point to where you stored the the WET file (external hard disk), and it will restore your personal files and settings. Reinstall any necessary applications.

If you don't have 64 bit install media for Windows 7, you can download the corresponding edition you have a license for from the following link:

Windows 7 Home Premium (x64) - 64 bit


Windows 7 Professional (x64) - 64 bit


Windows 7 Ultimate (x64)* - 64 bit

Boot from the Windows 7 DVD

To learn how to change your BIOS options to boot from the DVD drive, the following tutorial:


http://notebooks.com/2011/05/05/how-to-load-bios-and-change-boot-configuration/


Click Install Now

Accept License Agreement

When the option is displayed to select an installation type, click (Custom Advanced)

select the disk partition where you would like to install Windows 7 Click Next.

You will receive the following warning:

The partition you selected might contain files from a previous Windows Installation. If it does, these files and folders will be moved to a folder named Windows.old. You will be able to access the information in Windows.old, but you will be able to use your previous version of Windows.

(At all cost, do NOT click anything named Format or Delete or Partition. So even doing a custom install, your personal files are still preserved. Click OK

Setup will now start the installation. During the installation, your machine will be restarted several times.

When the installation is complete, you can complete the Out of Box experience such as selecting your laptop, create a username, password, your time zone. You can then proceed to download the latest updates for Windows and reinstall your applications and drivers.

You can then recover your personal files from the Windows.old folder and reinstall all your applications and drivers.

Thank you for this posting these directions.  I purchased a Windows 7 Professional - 64bit upgrade disk through our College Microsoft HUP program.  Can I use this disk and follow the procedure you listed above or should I download and install the Windows 7 Professional 64Bit X17-59186.iso image listed?

I had hoped to upgrade my WinXP 32bit to Win7 64bit.  I teach a class in PC Hardware technology and custom built a new PC with an AMD A10-7850 processor and a Gigabyte 64 bit motherboard.  In the process of transferring the hard drive from my old system to the new hardware we trashed the XP drive and its operating system.  I have spent the last 5 weeks attempting to install a 64 bit OS.

Your technical insight would be greatly appreciated.

If what you purchased includes Service Pack 1 then the "Upgrade" disk you purchased would be identical to what I listed above as it is the product key that determines if you have the "Full" or "Upgrade" for activation purposes.

 Good day,

I attempted to install Win7 Pro 64 on my system hard drive.  It is a 1TB drive and has an unallocated 450GB partition.  When I attempted the install I received an error: "Windiws cannot be installed to this disk."  Details: The selected disk has an MBR partition table.  On EFI systems, Windows can only be installed on GPT disks: 

Does this imply that I must purchase another disk drive or wipe this disk out, format it and restart again?

Sincere thanks,

  John Finkler
