So what's wrong with OEM? Same OS. It's the key you are using that is preventing you, you are using the product ID.
Wrong. Read my above posts. You've come in late. I have the 25 digit
Key - but it's the key to the OEM version and not the full retail version.
I have read the whole thread, I've installed windows hundreds, if not well over 1000 times. I was IT Admin at a school for 18 years. There is no difference between OEM and retail in the OS. OEM is for shops that build computers (Original Equipment Manufacturers) and is just a way for them to buy it cheaper than the retail version, no fancy packaging etc. The OS is exactly the same. I'm not wrong, you just don't understand and seems you do not want to.

Quote:What Does Windows 7 OEM Mean?
by Nick Davis, Demand Media
Windows 7 Original Equipment Manufacturer is a version of the Windows operating system available to computer manufacturers and companies that build computer systems. A company can purchase Windows 7 OEM versions for any computer systems it builds and plans to sell to others. OEM versions are intended for computers that are already built, are being built for use within a company or for any computers already containing another version of Windows.
Intentions
Windows 7 OEM versions are intended for server and PC manufacturers including HP, Dell, Toshiba and others. These versions are also intended for PC assemblers including commercial and individuals who are building computers from parts, for resale through a company. Companies cannot buy Windows 7 OEM from an area office supply, computer or electronics outlet, though. The package is available directly from Microsoft and third-party resellers including online resellers.
Limitations
Windows 7 OEM versions are not scaled-down or missing any components. The versions work exactly like end-user versions and include the same pre-installed applications including Internet Explorer, Windows Media Player, Windows Explorer and other applications. Windows 7 OEM versions do not contain free phone or technical support, however, because the computer manufacturer is supposed to provide support.

Licensing
Each Windows 7 OEM version contains one license, an end user license agreement (EULA), and is intended for one computer. The license includes a product key that you must enter when installing the operating system on the recently built computer. The operating system installation process works the same as with other Windows versions -- a wizard guides you through the installation process.
Windows Activation
Like other Windows versions, buyer must activate the operating system within 30 days. Activation is done via the Internet or by calling Microsoft’s registration service. Activation is free and the OEM software can be reinstalled activated on the same computer as many times as necessary. The buyer cannot move the Windows 7 OEM version to another new computer or deactivate the version and move it to another new computer.
Selling
When selling a computer containing Windows 7 OEM, you need to attach or include the Windows Certificate of Authenticity with the computer. The certificate is included in the Windows 7 OEM packaging and lets the computer buyer know that the version of Windows on the computer is not a pirated or bootlegged copy. The Windows Certificate of Authenticity contains the Windows product key and information about the Windows EULA.

edit2: You even said you were trying to use the product ID a couple of pages back
Quote:Thanks Kat - but I tried that source ages ago and got knocked back because the product key I gave them was only for an OEM version (Pre-installed version) - and only contains 20 digits instead of the required 25.
If your KEY is 20, it's not the KEY but the ID.
