questionshow to upgrade windows?


The first question I would ask is whether or not your computer hardware supports the 64 bit operating system.



My hardware does support 64bit OS.

The problem is that all the documentation I read is not very clear.

From Microsoft:

"Can I upgrade from a 32-bit version of Windows to a 64-bit version of Windows?"

"No. If you are currently running a 32-bit version of Windows, you can only perform an upgrade to another 32-bit version of Windows. Similarly, if you are running a 64-bit version of Windows, you can only perform an upgrade to another 64-bit version of Windows."

Then the next paragraph utterly confuses me:

"If you want to move from a 32-bit version of Windows to a 64-bit version of Windows or vice versa, you'll need to back up your files and then choose the Custom option during Windows installation. Then, you'll need to restore your files and reinstall your programs"

I understand that no matter what, I will need to do a clean instal.
But I guess my real question, is can I do this with an Upgrade Version, or do I need to buy a Full Version of Win 7 Pro 64 bit.


There should have been a copy of the 64bit Win7 in the package with the 32bit version... Load the 64bit disk in the drive after backing up all your data off the machine and do a fresh install...


The best upgrade for Windows is Linux.


@durkzilla: Thank you, that 2nd link in your post was EXACTLY what I was looking for.


@lparsons42: I spent several years using various linux distros either solely, or on dual boot. (Linux always being primary in my usage.)

...And in my experience that is entirely false, a statement. Not only in the truth of it being an incompatible comparison in terms of upgrade/downgrade, but in my opinion of its merit. I know of no distro preferable, by me, to Windows 7 except in terms of cost.

(I see no need to back up my opinion with fact, since I'm responding to a similarly unsupported statement.)

Just FYI, I'm not one of the jerks that downvoted you. I'll upvote you anyways, because I miss being a linux troll. :)


You can use an upgrade to clean install if you use the "double install" method. Install as Custom first then install as Upgrade over it. Leave the key blank the first go-around and input it the second time.


You will have to do a clean install, but your key will work with the 64-bit version. You will not have to do the double install version since Windows is on your machine. Even if you format as long as the install disk sees that Windows is on your machine it will let you install and use your upgrade key.

Like other people have mentioned your key allows for an install of either the 32-bit or 64-bit version of the OS. You can only have 1 installed at a time though. You can't use the same key to install 32-bit on one partition and 64-bit on another.


@gregorylikescheapstu: I originally started using Linux because I didn't want to pay for Windows. Then I realized that Linux is orders of magnitude more stable than Windows, and have switched to Linux almost exclusively. If it weren't for a few pesky things that refuse to run properly in Wine (all of which involve hardware with windows-only drivers), I wouldn't have anything under my command running any version of MS Windows, anywhere.

If you consider expressing support for a more stable OS to be "trolling", so be it. It still astonishes me that there are so many people who consider formatting their HD to reinstall their OS to be a reasonable way to "fix" an unstable OS. The proper way to fix an unstable OS is to replace it with a stable one, not replace it with a new generation of the preexisting instabilities.
