(Related : How can I upgrade from Windows 7 to Windows 8 and keep my files and applications? )

I'm trying to upgrade my Windows 7 Pro (msdnaa) to Windows 8 Pro (msdnaa).

The Windows 8 is the final version (I don't have access to previews on msdnaa anymore).

As you can see on the related question accepted answer, Windows 8 should give an option to keep installed programs. But it does not. The only available options are "Keep only personal datas" and "Nothing".

Any idea ?

I'm running with SP1. I've got two partitions (one of them only contains data of a virtual machine). The two operating systems have the same architecture (64 bits).

Screenshot, except that I don't see the "Keep Windows settings, personal files, and apps" option :

Are they the same architecture (32, and/or 64 bit)? – Ƭᴇcʜιᴇ007 Sep 14 '12 at 1:55
Yes. Furthermore, it seems that upgrade shouldn't be possible at all if the two architectures were different. – Nison Maël Sep 14 '12 at 2:09
Ok, that's what I was getting at. Maybe edit that info into your question. Also perhaps include partition and drive types (dynamic, basic, GPT, NTFS, software RAID, etc.), service pack levels, etc. – Ƭᴇcʜιᴇ007 Sep 14 '12 at 2:17
Are you by chance trying to upgrade Windows 7 x86 to Windows 8 x64 cause that isn't possible. Furthermore if you don't have access to MSDNAA anymore how do you have a copy from MSDNAA ( its actually called Dreamspark Pro ). – Ramhound Sep 14 '12 at 11:34
No, I'm upgrading from x64 -> x64. And I have access to the MSDNAA. But the Consumer Previews are not in my interface anymore (so I can't have downloaded the CP instead of the RTM) – Nison Maël Sep 14 '12 at 13:10

This is by design. Windows is not being upgraded, but being replaced with the new version. The registry is not being imported, nor are older applications.

You are normally able to upgrade Windows 7 Pro to 8 Pro. I'm pretty sure the OP is asking why he can't. – Ƭᴇcʜιᴇ007 Sep 14 '12 at 2:02
Yes, I'm trying to do an upgrade, not a reinstallation (upgrades are done when the OS is booted, reinstallation are using the live cd). – Nison Maël Sep 14 '12 at 2:11
To my knowledge the licence is upgraded and thats it. Windows 7 will not be upgraded, but replaced. – Keltari Sep 14 '12 at 2:19
The license is not actually replaced, once Windows is upgraded, the original license depending on some factors ( Retail License vs OEM License ) could actually be also used on another computer. – Ramhound Sep 14 '12 at 11:40
@Keltari According to Microsoft you can bring your data, settings, and apps along from Win7 only.… – imtheman Sep 14 '12 at 22:44
