Windows 7: Upgrading from Windows 7 32bit to Windows 7 64bit

Upgrading from Windows 7 32bit to Windows 7 64bit

Hello, I am wanting to upgrade my Toshiba Satellite L750/0T1 from Windows 7 Home premium 32bit to Windows 7 Home premium 64bit.

I understand that this process will wipe all my data, and I am wanting to do a clean install during this upgrade.

I have also checked that my laptop is compatible with 64bit.

First of, would I be able to upgrade using my existing Windows 7 Product Key?
Or would I have to buy a new Windows 7 Home premium 64bit OS with a new Product Key?

I bought my laptop from DSE a few years ago and was wondering if they would be able to make a deal of some sort that would save me from buying a new Windows 7 Home premium 64bit OS.

Would there also be anyway for me to keep a copy of the Windows 7 Home Premium 64bit Disc?

Any help with this would be greatly appreciated .

Your key will work for 64 bit, you don`t have to buy anything.

Do you have a 64 bit disc ?

No I don't, I don't have a disk for 32bit either.

My laptop came preinstalled with Windows 7 Home Premium 32bit.

I have tried doing an ISO file, but when I run it there is always an error about SPWIZENG.dll and autorun.dll?

Would I be correct in downloading the 64bit version of Windows 7 Home Premium and using my 32bit product key when I do a clean reinstall?

Is there a process for downloading the correct ISO file and burning to a disk that I could follow, to make sure I do it correctly?

Read the 1st tutorial, it will tell you all you need.

AFTER reading the tutorials, ask any questions BEFORE you start.

You don`t have a 32 bit key, you have a Windows activation key

And please download the network drivers for your computer and put on a cd or a flash drive (usb stick) before you start, so you can install them and get online once you`re done with your new install.

For the first step would I download a 32bit ISO or a 64bit ISO (I assume 64bit since I am upgrading?)
i.e would it be the x64 or x86?

Also which one of these would be the correct one to download?

  • Windows 7 Home Premium x64 SP1 U (media refresh)
  • Windows 7 Home Premium x64 SP1 (old)
  • Windows 7 Home Premium x64 RTM
  • Windows 7 Home Premium N x64 RTM
  • Windows 7 Home Premium x64 RTM (not bootable)
  • Windows 7 Home Premium N x64 RTM (not bootable)
I have also noted that some of the downloads have not been consistently available. Would this affect me downloading the ISO files? Would I have to use a software downloader of some sort?

Thanks, would it also be best to still use the Windows 7 USB-DVD Download Tool?

Or do you have a better suggestion?
I know some people have said burning a disc at a lower speed works best.

You don't need a software downloader. All you need is a blank DVD.

How to burn the ISO varies depending on which burner application you use.

Here's how to do it using just Windows 7:

Burn a CD or DVD from an ISO file

Here's how to do it with Imgburn, a popular and reliable program:

The Windows 7 USB-DVD Download Tool is a simple way to burn a bootable DVD or make a bootable USB stick. I don't know why the call it a download tool.
