What is Original Equipment Manufacturer System Locked Preinstallation Activation?

Examples of Microsoft’s Major Partner Original Equipment Manufacturer (OEMs) are:

  • Alienware/Dell
  • Lenovo/IBM
  • HP/Compaq
  • ASUS
  • Acer
  • Samsung
  • Sony
  • Toshiba
  • MSI
  • Fujitsu

Microsoft Major Partner OEMs preinstalled Windows 7 on millions of machines. In order to save production time these Major OEM licenses utilised a BIOS based activation mechanism. The conventional way would have required the OEM to input a unique 25 digit product key and call Microsoft for every single machine…

This BIOS based activation mechanism is called OEM System Locked Preinstallation as an activation mechanism. Customised Windows 7 installation media inputs a generic product key known as a System Locked Preinstallation (SLP) key which results in offline product activation if and only if the System License Internal Code (SLIC) is valid i.e. the system has an eligible system BIOS. For more details on determining the SLIC see my BIOS/UEFI guide.

Lets take Dell and the Edition Windows 7 Professional for example. Every single Dell PC shipped with Windows 7 Professional OEM has the same product key 32KD2-K9CTF-M3DJT-4J3WC-733WD and this will show up in system properties as Product ID: 00371OEM-8992671-00524 (the first 5 digits differ depending on language, English is shown). A Dell Branded Windows 7 Professional Reinstallation DVD will automatically select to install Windows 7 Professional and input this product key and offline product activation if and only if the system has an eligible Dell BIOS and has been sold with Windows 10 Pro OEM (via downgrade rights), Windows 8.1 Pro OEM (via downgrade rights) or Windows 7 Professional OEM.

Lets take Dell and the Edition Windows 7 Home Premium for example. Every single Dell PC shipped with Windows 7 Home Premium OEM has the same product key 6RBBT-F8VPQ-QCPVQ-KHRB8-RMV82 and this will show up in system properties as Product ID: 00359OEM-8992687-00095 (the first 5 digits differ depending on language, English is shown). A Dell Branded Windows 7 Professional Reinstallation DVD will automatically select to install Windows 7 Home Premium and input this product key and offline product activation if and only if the system has an eligible Dell BIOS and has been sold with Windows Home Premium Pro OEM.

Note if your OEM e.g. Dell have only certified a particular model to run Windows XP or Windows Vista, there will not be a Dell BIOS update available and hence the system will not be certified for Windows 7 OEM System Locked Preinstallation and Product Activation will fail.

To identify if your system has been installed using a Microsoft’s Major Partner OEM SLP you will have a product ID of the form:

  • xxxxx-OEM899xxxx-xxxxx

You may check your activation status by pressing [Windows] and [Pause|Break] or by going to Start and right clicking computer and selecting properties.

windowsactivated

If there is no OEM in the Product ID you have a Retail or Volume license and these licenses are not supported with this guide…

Note if the product ID has the form:

  • xxxxx-OEM910xxxx-xxxxx

You have Windows 7 installed via the unique 25 digit product key from the Code of Authenticity (COA) affixed to your computer.* This activation mechanism works however OEM System Locked Preinstallation is in general preferred.

* It should be noted that there are two very poorly understood additional OEM licenses which may lead to confusion. These two licenses are Commerical OEM System Builder Licenses and Manufacturer Refurbisher OEM Licenses. These licenses do not have OEM System Locked Preinstallation and are hence not supported in this guide.

Although OEM media which applies OEM SLP is preferred. For Windows 7 Microsoft had a terrible Digital Distribution with only Retail installation media being made downloadable. There is no official OEM download for most OEMs. For Dell systems:

This Dell branded Reinstallation media is more up to date than Microsoft’s offerings and automatically applies OEM SLP.

Identification Stickers for Windows 7 OEM System locked Preinstallation

I will mention identification stickers now…

If the system is shipped with a Windows Pro OEM Edition and is eligible for Windows 7 Pro OEM System Locked Preinstallation:

win10ProWin8Pro

If the system is shipped with a Windows Home OEM Edition and is ineligible for Windows 7 OEM System Locked Preinstallation i.e. product activation will fail:

Win10Home Win8Home Win8Bing

If the system has an OEM branded Windows 7 COA it is eligible for OEM system locked preinstallation from that OEM:

Windows 7 COA

These COAs are often found under the battery compartment or computer cover to prevent fading:

Laptop COA

If the COA is unbranded it is not eligible for OEM System Locked Preinstallation. A commercial OEM COA even for a Pro Edition has no Downgrade Rights as tit doesn’t support OEM System Locked Preisntallation.

Unfortunately there are many systems sold with incorrectly licensed Windows 7 COAs. A HP system sold with a Dell branded COA or a Dell branded COA sold without a Dell system is non-genuine. This can become confusing for end-users when they have bought an older Dell Windows Vista system and this PC has had its Windows Vista COA removed and replaced with a Dell branded Windows 7 COA. Needless to say these non-genuine COAs aren’t supported and OEM System locked Preinstallation will fail for system models where no BIOS Update is available to certify the system to run Windows 7.

What is the Activation Backup and Recovery Program?

OEM system locked preinstallation keys cannot be used in the traditional manner… If one uses traditional Retail installation media (or Commercial OEM installation media) downloadable from Microsoft OEM SLP will not be applied.

If one attempts to input the OEM System Locked Preinstallation Key during installation:

Win7-9

Or via Change your Product Key:

4

It will result in an unactivated Windows Edition.

The Activation Backup and Recovery (ABR) Program is a third party utility which allows one to Backup and Reapply OEM System Locked Preinstallation. The backup procedure obtains the OEM cert file and OEM SLP key in text form however because the cert file files are in mass circulation e.g. every single Dell Windows 7 Professional OEM install has the same cert file and same OEM SLP key, in most cases the Backup feature is not required.

The use of the ABR Recovery utility alongside the cert file means one can install Windows 7 Retail without a Product Key to initiate a 30 day trial and then apply OEM System Locked Preinstallation.

activate

As ABR only applies OEM System Locked Preinstallation it will only work on eligible systems. If the cert file and OEM SLP key is used on an illegal system you will be given 9 days to input a valid product key.

This tool is useful if there is a product activation issue and Dell/HP OEM SLP needs to be reapplied without reinstallation or if one has a Retail Installation DVD.

Download Links and System Locked Preinstallation Keys

Most major OEMs are supported with this collection:

  • Alienware/Dell
  • Lenovo/IBM
  • HP/Compaq
  • ASUS
  • Acer
  • Samsung
  • Sony
  • Toshiba
  • MSI
  • Fujitsu

These were obtained from here which covers a few more less common major OEMs.

Restore

Download ABRbeta (Windows 7) and the Activation Files.

The following steps may look a bit more complicated than they actually are. Essentially all you are doing is extracting two folders. One has two programs activation_backup.exe and activation_restore.exe. The cert and product key files must be copied to this extracted folder so the activation_restore.exe can be launched.

Extraction

Right click the “Dell/HP ABR Activation Files Vista and 7” and select extract all.

1

Opt for the extracted files to be in downloads.

2abr

Select to open the folder and snap it to the right. Next snap downloads to the left. Extract ABRbeta.exe (Windows 7) or ABR.exe (Windows Vista) by double clicking it.

3abr

Accept the warnings to run it

4abr

Again select the default location of downloads and select extract

5abr

You will now have a folder called ABR, open it to the left and open the ABR activation files to the right.

6abr

Activation-Restore.exe

Select your version of Windows.

7abr

I will use Professional as an example. Move the backup-cert.XrML and backup-key.txt file to the ABR folder.

8abr

Once these files are copied across run activation-restore.exe by double clicking it and accept any user-account control. It will input the Major OEM SLP key from the backup-key.txt and use this with the backup-cert.XrML to activate Windows Vista or Windows 7.

Note: You may be prompted to continue press [y] and [enter] if asked (usually you are asked this only if you entered a product key during installation which was not recommended).

Product Activation Check

Restart your computer and check your activation status by pressing [Windows] and [Pause|Break]. Windows 7 should be activated in the exact same manner as the OEM factory install.

windowsactivated

The rest of this guide is just additional information… and won’t be required in most cases…

Backup

In the rare cases where the Cert file is not downloadable or you wish to backup your own one.

Check to see if your computer is running an OEM license by looking at the product ID in System Properties (press [Windows] and [Pause|Break]:

windowsactivated

Look at your Product ID; the product ID of a major Windows 7 OEM license with OEM SLP will have the form of xxxxx-OEM-899xxxx-xxxxx and for a major Windows Vista OEM license the SLP will have the form xxxxx-OEM-733xxxx-xxxxx. The ABR backup will not work for a system without such a product ID.

Download ABRbeta (Windows 7) or ABR (Windows Vista). Extract ABRbeta.exe (Windows 7) or ABR.exe (Windows Vista) by double clicking it.

3abr

Accept the warnings to run it

4abr

Select the default location to extract.

5abr

This will extract to an ABR folder, open it.

6abr

Launch the activation_backup.exe

abrbackupfull

Accept any UAC prompts, you will now have a backup-cert.XrML file and backup-key.txt file created.

abrbackupfull2Copy the ABR Folder to a safe place for later use. These can be used later to restore your OEM product activation.

If you have the cert file for any OEM thats not Dell or HP you may add the files to a zip file and save this to OneDrive and share it in the comments section. It can help other users with Vista or 7 from your OEM which wish to clean install and whose hard drive or installation has failed and have no recovery media.

My Dell Shipped with Windows Vista OEM – Can I Install Windows 7 OEM Instead?

Windows 7 OEM was a Free Upgrade for Late Windows Vista OEMsystems. Microsoft marketed Windows 7 OEM as a “Free Upgrade” to Windows Vista OEM if the system was sold 6 months before the release of Windows 7 OEM. Windows 7 OEM was released on the 22/07/2009.

This “6 months” is just a rough guide. In reality it is the hardware which dictates the ability to perform the Free Upgrade from Windows Vista OEM to Windows 7 OEM… Lets take the Dell OptiPlex 760 system which was released by Dell on the 29th of October 2008. It may have been sold any time from November 2009 to December 2009. This makes the vast majority of these models sold in the 6 months before the release of Windows 7 OEM (Microsoft’s marketing Window). Irregardless of the precise point of sale, Dell the OEM classify them as the same model and they have the same BIOS update making them eligible to run Windows 7 Pro OEM.

As a consequence most models released around this time are eligible to run Windows 7 OEM provided they have their latest BIOS update applied.

  • The latest BIOS Update in many cases updates the SLIC to 2.1 from SLIC 2.0 making the system valid for Windows 7 OEM SLP (for more details see my BIOS/UEFI guide).

Dell models released in this time period are eligible to run Windows 7 using Dell OEM SLP providing their following BIOS update is applied.

After applying the latest BIOS Update check to see if your SLIC is 2.1. If it is WIndows 7 OEM will activate if it isn’t Windows 7 OEM will fail to activate. For more details on checking this see my BIOS/UEFI guide. This check is needed on the Mid 2008 systems (I don’t have all the hardware to test).

Ineligible System Example Test

This is just a demonstration to show that the Activation Backup Recovery program or Dell Windows 7 Reinstallation DVD won’t work on ineligible systems.

A Dell Latitude D820 was used with an Vista Business COA in this test. It has a genuine Windows 7 Upgrade license and was later activated using it.

This system was only sold by Dell with Windows XP and Windows Vista, hence the latest BIOS revision only has markers for Windows XP and Windows Vista. If one tries installing with a Dell Windows 7 Professional Reinstallation DVD or using the ABR files for Windows 7 which mimic the activation mechanism of the Reinstallation DVD on this system, Windows 7 will not activate. Instead you will get a 9 days until automatic activation as shown below.

When you click to activate now you will be unable to activate with the Dell SLP key and will be prompted to enter another product key. After 9 days you will get:

55 thoughts on “Windows 7 OEM – Applying OEM System Locked Preinstallation Activation using the Activation and Backup Recovery Program

  1. Hi,
    Have downloaded the Win7 Ultimate SP1 and did all what you said here. Once I start the installation in a new HDD of my Inspiron M5040 an error come up saying:

    Have tried to find a driver for the HDD in DELL support site but the one available driver is not working. Tried the HDD site, not luck.

    Any suggestions as to how resolve this?

    Thanks!

  2. You’re right. I made the error entry in caps and was deleted by the blog. Anyways, what the error say is: No drivers available, etc…This is a brand new Hitachi HDD with the new Advance Format system file.

    1. M5040 is an AMD system and not an Intel one. I am less experienced with AMD than Intel systems as I prefer Intel. According to WD you shouldn’t need a driver for AMD:
      http://www.wdc.com/global/products/features/?id=7&language=1

      Obviously you are finding that you do. Its the AMD A50M Chipset family so you need the AMD AHCI drivers.
      They might be obtained within the Chipset driver listed by Dell R313347. Once extracted with 7zip there is a folder called packages and within it a folder called drivers. I would try selecting this folder to load during the Windows setup. However I am not sure if the Dell driver will cover an AF HDD so I would go for the one direct from AMD:
      http://support.amd.com/en-us/download/chipset?os=Windows

      Try the top one. Once extracted with 7zip select the drivers folder:
      13-4_vista_win7_win8_32-64_sb\$_OUTDIR\Packages\Drivers

  3. I have completed a hardware upgrade on a Dimension E510 and purchased a Dell reinstallation DVD for Windows 7 Pro. The installation went fast and smooth but the Product Activation Code I’ve purchased from a noted online software retailer is not working. I wrote them and they sent a second PAC which did not work either. I’m a bit confused right now about the article above but is it possible that I need to buy the PAC from Dell to activate the copy of W7 Pro or will the procedures outlined in your article above work for me?

    Thanks for your answer.

    1. Neither the Reinstallation DVD or the ABR program (which mimics the activation mechanism of the Reinstallation DVD) will work on your system.

      The Dimension 5100 was sold by Dell with only Windows XP and maybe in some cases Windows Vista. Thus Dell have only placed the markers for Windows XP and possibly Windows Vista in the system BIOS. They have not placed the Windows 7 markers in the BIOS and the activation mechanism will therefore sees an invalid BIOS and hence will not activate. See notes on ineligible systems:
      http://dellwindowsreinstallationguide.com/a-clean-install-of-windows/microsoft-product-activation/the-activation-backup-and-recovery-program-windows-vista-7-version/#Ineligible

      A retail license should activate directly. See here for details describing the differences between OEM and Retail:
      http://dellwindowsreinstallationguide.com/a-clean-install-of-windows/the-oem-or-retail-license/

      In your case you have purchased a Reinstallation DVD and a COA so phone activation may work:
      http://dellwindowsreinstallationguide.com/a-clean-install-of-windows/microsoft-product-activation/phone-activation-windows-vista-7/
      In reality a Dell Windows 7 COA should not be sold separately from a Dell system so it is also possible you were sold a non-genuine license. Theres lots of piracy of fake Windows 7 COAs and for these reasons COAs are removed in Windows 8 and later. The system builder OEM license is usually just Microsoft branded.

      1. Thanks. This is pretty frustrating since I had upgraded my wife’s PC at her office which was from the same era as this one but was of the OptiPlex variety, I think. The cases were shaped the same except my wife’s was taller. It runs W7 with no problems at all and validated itself. The little E510, so far, runs W7 just fine, too.

        The PAC was purchased from buycheapsoftware.com, not one of those on ebay that I looked at prior to the purchase and didn’t trust in the slightest. I can’t see them selling fake licenses but they may not know about the markers you speak of.

        So phone activation through Microsoft is the only possible way you see to activation? Your link above points to a page that is no longer there but it is one of the options available after the activation attempts I’ve made have failed.

        Thanks again.

      2. Sorry I updated that link, it should work:
        http://dellwindowsreinstallationguide.com/a-clean-install-of-windows/microsoft-product-activation/phone-activation-windows-vista-7/
        If your wifes was an OptiPlex 760, Dell sold it with Windows 7 so the latest BIOS does have the markers for Windows 7 Dell OEM activation. The OptiPlex 745 and 755 do not similar to the Dimension E510.

        I would be very cautious of buying software like this:
        http://www.buycheapsoftware.com/details~productID~5975.asp

        “When buying Microsoft software as a digital download, we recommend that you avoid auction sites and peer-to-peer (P2P) file sharing sites. At the moment there are a limited number of sites where you can legally purchase digital downloads of Microsoft software. One example is the online Microsoft Store, where you can buy a wide variety of genuine software and hardware directly from Microsoft (in select markets). Additionally, you can purchase a digital download of Windows at http://www.windows.com/shop.
        With the exception of Product Key Cards distributed with Certificates of Authenticity (COA’s), Microsoft does not distribute products keys as standalone products. If you see a listing on an auction site, online classified ad, or other online page advertising product keys, it’s a good indication that these keys are likely stolen or counterfeit.”
        http://www.microsoft.com/en-gb/howtotell/Software.aspx

        i.e. Microsoft don’t simply allow giving out of product keys via telephone.

  4. We were in town today and I looked at my wife’s old computer again and it’s actually a Dimension 9200.

    The PAC I bought for the E510 was this one:
    http://www.buycheapsoftware.com/details.asp?productID=5748. They’ve been around for a long time and we’ve purchased a lot of software from them personally as well as for my wife’s office an the plaice I used to work as well. The PAC was sent via e-mail and they attached this to the reply I got when I asked them the first time about the first PAC not working:

    Product Key : XXXXX-XXXXX-XXXXX-XXXXX-RJ3PX (my X’s)
    Validity : Valid
    Product ID : XXXXX-OEM-9309671-17961
    Activation ID : da22eadd-46dc-4056-a287-f5041c852470
    Edition Type : Professional
    Description : Windows 7 Professional OEM:COA
    Edition ID : X15-37341
    Key Type : OEM:COA
    Crypto ID : 186

    I’ve finally arrived at a point where I can try the phone activation. If it doesn’t work I guess I’m just out of luck on the upgrades and whatever. Just hope I can get my money back on the W7 Pro license.

    Thanks again.

  5. I can’t believe it! Using the phone activation procedure the activation was a success! Did it override the BIOS markers or something?

    1. The BIOS SLP activation is the main activation mechanism of the Dell Reinstallation DVD. Inputting the unique 25 digit product key on the COA and activating by phone is a secondary activation mechanism usually reserved to the rare cases when the SLP mechanism doesn’t work. You should be fine provided that site doesn’t sell the same PAC to multiple customers.- I’m still not sure if its a legitimate license you have and have reported the site to Microsoft Support.

  6. Fine by me. I KNOW there’s quite a few that need to be reported on Ebay.
    When starting the phone activation procedure how is the, I think, 36 digit code that you read off to Microsoft derived? Does it come from the PAC I tried to use to activate it or the embedded OEM PAC that was not working to begin with?

  7. Philip – great site. Thank you for putting this together.

    Unfortunately I am stuck. I feel like I have been going in circles trying to activate Windows 7 on this Machine.

    Inspiron 545s Desktop came with Vista Home Premium with a free Upgrade to Windows 7. This worked well for years. After heavy use I was advised to reinstall Windows.

    I have gone through reinstalling several times and always find Windows 7 needs to be activated with a product key. No product key given with the Dell upgrade disks. I am back at this same spot now.

    I installed Vista first which showed as authentic and activated. Then I used the Dell upgrade disks that were provided originally to upgrade, then installed all of the Windows updates. The machine is working great. But I am stuck with 29 days left and I can not figure out how to activate. I am going nuts. I considered staying with Vista but cant use Office 365, ++

    Can you point me in the right direction?

    1. If you have BIOS A12 and it still doesn’t activate then Dell hasn’t added the SLP activation mechanism to this machine. Usually if Dell have Windows 7 drivers the latest BIOS should work with the Dell Windows 7 SLP activation.

      Upgrade discs should have came with a retail upgrade product key.

  8. Hi Philip,

    I have a Dell latitude laptop on which I fully erased the Windows 7 with an Arch Linux for two years.

    I now want to switch back to Windows 7 but I have nothing backed up from the original Dell install. I also could have flashed the BIOS before even if I don’t remember doing it (does it erase the OEM license?).
    Do you think it could be a problem for reactivation? Should I prefer the dell installation media over the retail one when following your “clean install of windows” guide?

    By the way, thanks for these awesome guides.

    1. The Dell Windows Reinstallation DVD applies the Activation Mechanism automatically. For retail media you need to use the ABR program to apply the same activation.

      The ABR program will work on any Dell BIOS which came with a system shipped by Dell with Windows 7 (including any legitimately updated Dell BIOS). It’ll also work on any Dell systems shipped with Windows 8.0/8.1 Professional.

      You should have no problems using either for activation.

  9. How will this work on Dell Vostro 220s factory installed VBus OEM COA label with downgraded rights to XP Pro? Never obtained Dell’s FREE Win 7 Pro upgrade disk…..

    1. For that model, Dell never released Windows 7 drivers which is why I made an unofficial set:
      http://dellwindowsreinstallationguide.com/driver-sets/vostro-desktops/vostro-220s-windows-7-64-bit/
      This means the latest BIOS for that model only has markers to accept the Dell Windows Vista Business SLP key and Windows XP Professional SLP key. i.e. was not upgraded to have Windows 7 Professional markers so a Dell Windows 7 Professional Reinstallation DVD or the ABR program with Dell cert files on a Windows 7 Professional install will be rejected and hence fail to activate.

      If you want to run Windows 7 on it you will need a retail license (these are quite pricey as Windows 7 has stopped being sold). It will work with the Windows Vista Business.

      My advice is to install Windows 10 Technical Preview and use it to evaluate Windows 10 64 Bit until its finally released. At which point you should be able to purchase Windows 10 at a promotional price.

      1. Thank you Philip. I have purchased a Win 7 Pro OEM from BestBuys. I will try to activate the OS with that OEM Disk Key. Will post results at later time.

        It’s a shame Dell doesn’t always appreciate your valuable assistance to us ‘untechies’ at large…

      2. The OEM disc from Best Buy will be a generic OEM disc and not a Dell OEM disc. It therefore won’t require the SLP markers in the BIOS and will activate with its own 25 digit product key. The generic OEM is similar to the retail license however has 2 limitations; once installed on the desktop it is non-transferable (forever tied to the desktops motherboard). The second is that the product key will not work with Microsoft’s Software Recovery Tool (which is pretty non-functional anyway).

        The Windows 7 Generic OEM license will be eligible for the free upgrade to Windows 10 in Late Summer.
