Windows 7: 32 bit --> 64 bit

32 bit --> 64 bit

I'm currently running Windows 7 32 bit. I had purchased and used the upgrade disk to move from the machine installed Vista to Win7 in '07 or '08 after purchasing the Thinkpad.

I recently (after some informative discussions here) upgraded RAM from 2-->4GB. Of which, due to the 32 bit OS, I'm only utilizing ~3GB.

Given the increased performance resulting from the increase in memory plus that fact that now the 64 bit platform is no longer bleeding edge stuff and drivers are not an issue, I'm now seriously serioulsy considering moving to 64 bit so that I can utilize all 4GB of RAM.

From what I gather online, my Win7 upgrade disk has 64 bit on it and can be invoked somehow? I understand that the change will not preserve my files and that I'll need to reinstall all applications and data files?

2 questions:

1. Am I correct that the MS upgrade disk that I used going from Vista to Win7 can be used again to move from Win7 32 bit to Win7 64 bit?

2. Am I correct that I will then have only the OS on the machine and will need to reinstall all applications and data?

3. Does this idea sound even remotely reasonable :-)?

You cannot upgrade from Win 7 32-bit to Win 7 64-bit, it will have to be a clean install.

You will have to re-install all your applications and data.

Fine--but to confirm, I can do so using the same upgrade disk?

The 32 and 64 bit versions of Windows 7 are on separate discs. I do not believe the upgrade disc you purchased has 64 bit on it.

Markg,

Before you get to far along:

GRC*|*SecurAble: Determine Processor Security Features*|**

Run that program to 100% confirm that you can install and utilize a 64 bit os.

You can use dism to find out what images are on your dvd.

However, I will tell you in advance, MS only puts 32 bit versions on one dvd and 64 bit versions on another dvd.

DISM.exe /Get-WimInfo /WimFile:C:\test\images\myimage.wim

That's the general format that you need, but of course you have to put the actual boot.wim file in there. I thought I had a write-up on this but haven't found it yet. The end-result will be separate dvds.

The 32 and 64 bit upgrades come on separate DVDs. You may be able to use your license key with a 64 bit upgrade, if you can come up with installation media. (Some retail .iso files are on the Net, although we aren't allowed to post links. Web search may turn them up. Hint: mydigitallife.)

You can't do an upgrade-in-place for a 32 bit version of Windows to a 64 bit version. You'll have to re-install all applications.

Do 64 bit drivers exist for all of the peripherals in your notebook? You may want to run the 64 bit version of the Upgrade Advisor.

Markg,
Here's the dism command you will need:

dism /get-wiminfo /wimfile:e:\sources\install.wim

where E: is the drive with the Win 7 dvd
and you must run dism from an elevated command prompt, i.e., run cmd.exe as administrator.

The CPU is correct for the task but the Windows7UpgradeAdvisorSetup.exe is not. I've installed and run the thing twice and twice it has 'stopped working' and 'go online for a solution' simply resulted in the application closing.

It might be time to take a Zen approach to this thing, say it wasn't meant to be and simply stay put with my ~3.1GB of useable memory.

So if I found the media and if I downloaded the media and if I burned the ISO file to a DVD for installation can I assume that the opportunity to enter my current key to determine if it is acceptable will occur before the installation nukes my current drive?
