                                            Code of Authenticity (COA) and Windows Identification Labels

                                            Systems manufactured before 2012 were sold with a Windows 7 Code of Authenticity (COA). This contained the Edition of Windows 7 and a 25 Digit Product Key and was typically placed under the battery to prevent fading. This installation key works with Windows 10 Installation Media but will only activate with Phone Activation with Windows 7 Installation Media.

                                            Systems sold after 2012 have the following sticker to identification labels to indicate that they have an embedded Windows OEM License.

                                            OEM – Original Equipment Manufacturer

                                            The Windows Original Equipment Manufacturer (OEM) License is a Windows License supplied preinstalled with a device.

                                            This is typically the type of Windows License supplied with a Dell, HP and Lenovo computer which preinstall Windows on tens of thousands to millions of Devices. The Product Support for the Hardware and the Software is supplied by the Equipment Manufacturer and not Microsoft. We will refer to these as Major OEMs and the License as a Major OEM License.

                                            There is an additional OEM License called the Commercial OEM License. This License was designed for low volume OEMs for example a Medical/Scientific Instrument manufacturer who may make specialised hardware on hundreds to thousands of Devices and for independent local PC Shops who would build and sell hundreds to thousands of custom Desktop Computers and provide Hardware and Software Support to the End Customer. These OEM Devices are known as Commercial OEM Licenses. They were unfortunately predominantly incorrectly licensed as consumers often purchased these Licenses as "Cheap Retail Licenses". Commercial OEM Licenses do not have OEM System Locked Preinstallation Activation Mechanisms.

                                            What is OEM System Locked Preinstallation?

                                            Original Equipment Manufacturers (OEMs) like Dell preinstall Windows on millions of Devices. In order to avoid having to manually type an alpha-numeric 25 digit product key and calling Microsoft for Product Activation on every single computer they manufacture, they activate their devices using a different mechanism called OEM System Locked Preinstallation (OEM SLP).

                                            Below is a list of OEM activation mechanisms for different types of Windows Installation Media. It took some time for Microsoft to create downloadable multi-edition installation media that works with all Windows 7 OEM, Windows 8.0 OEM, Windows 8.1 OEM and Windows 10 OEM Licenses. These installation guides arose as I experienced these difficulties and found a series of unofficial workarounds which I shared with the Dell Community Forums and the popularity of these workarounds eventually reached Microsoft who implemented many of the suggested fixes in Windows 10 Version 1511 and almost all the suggested fixes in Windows 10 Version 1709 and later. For up to date installation guides see the following:

                                            Windows 10
                                            Windows 8.1
                                            windows 7

                                            The only fix that wasn't incorporated fully in Windows 10 Version 1709+ Installation Media is the activation mechanism involving direct SLIC 2.1 however the indirect activation mechanism Genuine Ticket can be used instead.

                                            MSDM – Microsoft Digital Marker

                                            For systems sold with Windows 8 OEM and Windows 10 OEM the 25 digit product key is not seen printed on a label but is embedded in the MSDM table of the UEFI BIOS. Windows 10 Installation Media downloadable from Microsoft will automatically input these product keys during installation and as it's multi-edition it will automatically select the correct Edition corresponding to the Windows Product Key. Although most people shouldn't need to, one can check if they have a MSDM by installing RWEverything.

                                            RWEverything

                                            The ACPI tables should load by default (if not select Access → ACPI Tables).

                                            SLIC – System License Internal Code

                                            For Windows 7, the 25 digit product key was printed on a CoA but it is typically not used during Windows 7 Installation. Instead Windows 7 is activated from Factory using OEM System Locked Preinstallation. For Windows 7 OEM SLP three things are required:

                                            • The System has a SLIC Version of 2.1
                                            • The Installation Media Inputs:
                                              • A xrm-ms File.
                                              • A Generic OEM SLP Key (Generic for the OEM e.g. Dell and the Edition of Windows 7 e.g. Professional).

                                            If all three requirements are satisfied OEM SLP is applied. Although most people shouldn't need to, one can check if they have a SLIC by installing RWEverything.

                                            RWEverything

                                            The ACPI tables should load by default (if not select Access → ACPI Tables).

                                            A SLIC Version of 1.0 is for Windows XP, a SLIC Version of 2.0 is for Windows Vista and a SLIC Version of 2.1 is for Windows 7. Systems shipped with Windows 8.1 Pro and Windows 10 Pro will have a SLIC Version of 2.1 in addition to the MDSM because they are eligible for OEM Downgrade Rights to Windows 7 Pro OEM.

                                            Windows 7 OEM Installation Media

                                            The Out of the Box Experience (OOBE) script calls the System Locked Preinstallation Script (SLP) script. The SLP script has two lines the first line installs the OEM.xrm-ms file and the second line inputs the generic OEM SLP key. This is the key for Dell Windows 7 Professional.

                                            This is the SLP script from a Dell unmodified Dell Windows 7 Professional Reinstallation ISO:

                                            cscript %windir%\system32\slmgr.vbs -ilc %windir%\system32\oem\OEM.xrm-ms
cscript %windir%\system32\slmgr.vbs -ipk 32KD2-K9CTF-M3DJT-4J3WC-733WD

                                            Windows 7 Retail Media or System Builder OEM Media does not contain an $OEM$ folder and will not apply OEM SLP and will instead ask for a Retail Product Key During Installation. This has caused a lot of confusion regarding OEM SLP.

                                            Applying Windows 7 OEM SLP Using Retail Media

                                            Retail Installation Media asks for a Product Key During Installation. We can uncheck "Automatically Activate Windows when I'm Online".

                                            Post Installation we can apply the OEM System Locked Preinstallation. Download the following:

                                            OEM.xrm-ms file  and SLP.cmd Collection

                                            Extract, select your OEM and then Edition of Windows 7. Copy the OEM folder directly to the C:\Drive. Right click the SLP.cmd file and select run as administrator, this will apply OEM SLP as per the factory settings.

                                            The slp.cmd script for Dell Windows 7 Professional is shown below. Note the OEM folder must be copied to the C:\ Drive directly so the script can find the OEM.xrm-ms file. 

                                            slmgr -ilc C:\oem\OEM.xrm-ms

                                            It can be modified to apply OEM SLP for your OEM by changing three files in Notepad or Notepad++:

                                            NotePad++

                                            EI.cfg

                                            The EI.cfg file is found in the sources folder:

                                            Where D is the Drive Letter.

                                            Open with Notepad and change Edition:

                                            Replace the 25 Digit Product Key with the correct one for your OEM and Edition of Windows 7 (below).

                                            OEM SLP Key Collection

                                            Many people on forums are instructed to use key finders to find their OEM Product Key and instead will find the OEM SLP key and fail to activate using it. These keys will only activate using windows 7 OEM SLP, they do not activate using other activation methods.

                                            Note the first 5 digits of the Product ID listed below will differ corresponding to the language installed.

                                            Genuine Ticket

                                            This Product Activation Mechanism is only required if the COA is faded (if it is not you can clean install Windows 10 using the key on the COA for initial one time Product Activation) and the system has never had Windows 10 Installed and Activated (if it has had Windows 10 Previously Installed and Activated the Activation Server will remember your Device and Automatically Reactivate provided you installed the correct Edition of Windows 10).

                                            To generate a GenuineTicket for the initial Product Activation Mechanism of Windows 10 you will need to first install Windows 7 with enough drivers to connect to the internet. Then on the Windows 7 Desktop you should attach a Windows 10 Bootable USB:

                                            Copy the GatherOSState.exe from the sources folder to the Windows 7 Desktop.

                                            Ensure you are online and right click gatherostate.exe and run it as an administrator:

                                            Accept the User Account Control Prompt:

                                            If your Windows 7 OEM Install is genuine and you are connected to the internet, a genuineticket will be generated.

                                            You can use this genuine ticket for Product Activation. Copy it over to your Bootable USB.

                                            Once Windows 10 is installed from the Bootable USB, copy the GenuineTicket over to the following folder and then restart your Computer.

                                            C:\ProgramData\Microsoft\Windows\ClipSVC\GenuineTicket

                                            Microsoft will check this folder upon startup and submit the genuine ticket and your system details to the Product Activation Server giving it the green light for Product activation. Once this is done you can clean install Windows 10 without a Product Key and it will activate when online. You won't need the GenuineTicket ever again.

                                            The genuineticket will only work on the same computer it was generated on.
