Windows 10: Windows upgrade to 64 bit failed

Trying to upgrade to 64 bit version of Windows 10 32 bit version. Upgrade failed due to wrong format on hard drive. Is there a way to fix this without having to reformat my hard drive?

Windows 10 Upgrade 32-bit to 64-bit

So, Windows 10 Upgrade is being rolled out worldwide, and I have 'reserved' my upgrade.

Currently my computer is running Windows 7 Pro 32-bit. I'm planning to 'upgrade' it to Windows 10 64-bit (via fresh install, of course).

After reading many references, these will be the steps I'll do:

1. Let the "Get Windows 10" app upgrade my OS to Windows 10 32-bit
   
2. Note the activation key
   
3. Download the Installation Media for Windows 10, but choosing 64-bit instead
   
4. Perform a clean install
   
5. Reactivate using the activation key in Step #2
   

(Of course I'll backup my data first.)

However, I still have some questions:

1. On Windows 7, the activation key does not differ between 32- or 64-bit versions. Is it still so with Windows 10?
   
2. Will I be able to download a different architecture on Step #3?
   
3. Is there anything I need to prepare beforehand?
   

Thank you for your assistance.

 

Can I downgrade From Windows 10 64 bit to 32 bit

Hello !

I Upgraded to Windows 10 64 bit , but it's a little slow

I failed to back to 32 bit

any help , please step by step

 

Upgrade to Windows 10 64-bit

First, note that you can *not* upgrade from either Windows 7 or 10 32-bit to 64-bit. There is no way to change the "bitness" of any version of Windows by an upgrade.

Since that means you have to do a clean installation, there's no sense in doing it in two steps. Just clean install 64-bit Windows 10.
