Re: Windows Vista x86 to x64?
 

Correct me if I'm wrong, but does HP even come in 64bit? Or was it basic that didn't...
I'm fairly certain one or two of the Vista installs didn't come in 64bit

Re: Windows Vista x86 to x64?
 

Nope, both Home Premium and Ultimate come in x64. (I'm using HP x64 right now)

Re: Windows Vista x86 to x64?
 

I knew Ultimate did...I used to run it, but didn't know HP did.
Ohwell.

For once Microsoft tech support comes in handy.

To answer your question:

Re: Windows Vista x86 to x64?
 

I'm using Home Premium 64-bit as well. All editions have 64-bit versions, if I'm not mistaken.

Re: Windows Vista x86 to x64?
 

Even the Starter Edition. :P

I think the reason Microsoft does not offer a 64-bit switchover, is because some copies of Windows Vista are only licensed for 32-bit, or 64-bit. Requiring the purchase of a 64-bit copy.

That, and that the CDs seem to be universal. Or at least the Ultimate CDs have all versions (even the Euro, and Starter versions) on the disc.

Yeah I think it just installs some modules or something.

But honestly there's no reason not to get x64.
I can't believe they aren't going with only x64 for win seven.

And I thought home basic only came in x32?

Re: Windows Vista x86 to x64?
 

That still exists? =p
The license keys are interchangeable between 32-bit and 64-bit versions of the same edition, e.g. you can use a license key from Home Premium 32-bit to install Home Premium 64-bit. All of the current generation Windows operating systems work like that (Vista Home Basic, Home Premium, Business, Ultimate, Windows Server 2008, Windows 7). The previous generations (XP Home and Professional, Server 2003) were different; 32-bit and 64-bit edition license keys were incompatible.
