Windows 7: OEM vs Retail

OEM vs Retail

Hello

I am starting this bew topic to seperate it from my query about downloading the Windows iso.

I have read numerous forums and keep getting conflicting results.

1) Does the Windows 7 Pro 64Bit OEM dvd contain the exact same software and structure as the retail disk?

2) Can the OEM DVD be converted to a all version disk?

3) Can the ei.cfg be edited to change the edition to another version or the channel be changed to retail?

I have read that the OEM and Retail dvd restriction has been removed and the retail and oem disk data is exactly the same since Windows 7 and it does not matter what disk you use.

However this seems to be shot down on various forums.

Does anyone have a oem and retail version that they can check?

The only difference between an OEM and "Retail" version is the OEM is tied to the system it is first installed on. Legally it cannot be installed on a different system. The Retail does not have that restriction, if you change hardware you can reinstall the Retail on the new hardware.

There's no way, that I know of, to convert an OEM to Retail (or vice versa). Whatever version it is, there is no changing it (legally). I suppose someone can hack it but then this subject goes beyond this forum.

There is nothing like an "OEM" disk or a "Retail" disk. The installer is exactly the same in both cases and Windows behaves in the very same way. The OEM/Retail is just a characteristic in the key used to activate, that just tell MS if it allows unlimited activation or just in the very first PC it was used.

Again, there is nothing like "an OEM disk". It's just the very same Windows installer. But yes, it can be changed to install whatever version you want. The only difference is the x86/x64 versions.

The channel doesn't depends on the disk, but the edition can be easily changed with ei.cfg. Moreover, just deleting it altogether will make the installer ask you when installing what edition do you want (home premium, professional, etc.). Of course, you can only activate the edition that matches your serial.

I'll add this post from your other thread which I think is what you are confused about,

What I believe you were reading about were branded OEM disc's which come from manufacturers like Dell, HP, etc. They don't require a product key in most cases because they will be made with their factory key already installed.

When most people talk about OEM discs they are referring to a system builder OEM which is the same disc as retail, but an OEM product key that cannot be transferred after installed, like a retail can. (One install at a time of course)

A Microsoft made DVD with Windows 7 OEM/Builders or a Microsoft made DVD Retail are the same. The COA key you activate either with is the difference.

If one has the desire to buy a Microsoft made Retail DVD for Windows 7, good luck.
Finding a legal copy of Windows 7 Retail is like finding hens teeth.
