Windows – upgrade Windows XP 32-bit to Windows 8 Pro 64-bit via an online download

windowswindows 8windows xpwindows-8-upgrade

I have a desktop that has Windows 7 64-bit OS installed on it. I heard about Microsoft's Windows 8 Pro online upgrade offer for $40, so I want to take them up on that. But I also heard a lot of "negative" stuff about Windows 8, so I'm not really ready to take my current Windows 7 and upgrade it to 8. What I was thinking to do is this:

I have my old desktop that came with Windows XP 32-bit OS. It now sits in my garage, but I still have a product key for it. I also got me a brand new SSD drive, so I thought to install Windows XP 32-bit on it and later upgrade it to Windows 8 Pro for $40, like they say in that offer. Then I'll use it for a while and if I like it, I'll transfer all the data from my current Windows 7 installation.

The issue is how to install Windows 8 Pro 64-bit on a Windows XP 32-bit?

Best Answer

  • First would install XP and all drivers on the SSD, then run the W8 upgrade assistant, it will scan and flag any Hardware, software or drivers that are problematic. Do this before you buy a license.

    A 64bit processor is required, so check your processor to see if it supports 64bit instruction set and is a 1 GHz processor or faster with support for PAE, NX, and SSE2.

    Yes you can upgrade from XP to W8 64bit if your hardware meets the requirements. But requires using DVD media, it cannot be done using the upgrade assistant.

    Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows 8? Yes, but you can't do this using Upgrade Assistant. If your PC has a 64-bit capable processor (CPU) but is currently running a 32-bit version of Windows, you can install a 64-bit version of Windows 8 Pro, but you'll need to buy it as a DVD and perform a custom installation. If available in your country or region, you can buy Windows 8 Pro from a participating retail store. You can also buy it online from the Microsoft Store in Austria, Belgium, Canada, France, Germany, Ireland, Italy, Japan, Netherlands, Spain, Switzerland, United Kingdom, and United States.

    Note: You might be better off buying a full copy of W8 "System Builder", it costs more but you can move the install and license to a different PC if the original PC you install it on dies or you just want to upgrade to a better PC. Buy it at any electronics retail store.
