ben100014 Posted April 5, 2009 Share Posted April 5, 2009 Hey everyone, I am about to upgrade my computer to a 64-bit Intel Q6600. I am curious, when I upgrade my computer to 64-bit hardware, will I be able to upgrade install to the 64 bit version of Windows? ( Without clean installing it) Thanks in advance.

cluberti Posted April 5, 2009 Share Posted April 5, 2009 No, you cannot upgrade from x86 to x64 with any version of Windows. You will always have to perform a clean install. Link to comment Share on other sites More sharing options...

And my data coped to another hard-drive?Yes, even if you do everything like you would in x86. It is simply not possible to upgrade from x86 to x64, as they're not the same OS (especially with XP - XP x64 is really Server 2003 under the covers). It's documented lots of places, but the most direct is here:Whatever version of Windows XP Professional x64 Edition you use, however, it will only be available as a fresh install. There is no provision for an upgrade from Windows XP Professional.Note that this applies for Server 2003 and Server 2008, Vista, and will apply for Windows 7 too.

Basically whats going to happen if you boot from the dvd, its going to roll your old install into a folder call windows.old. All the apps and programs wouldnt be installed already. Keep in mind you can do this with an upgrade dvd or full dvd. Link to comment Share on other sites More sharing options...
