The OEM or Retail License and Product Activation – Windows 8.1


I start with a brief introduction into Window licensing and have put together my recommended mechanisms for downloading Windows installation media and activating your product depending on your license type.

There are some more in depth notes which explain in more detail how to determine your license type and explain how the activation mechanisms and if necessary workarounds work.

For all intents and purposes Windows 8.0 Service Pack 1 is Windows 8.1 so anything mentioned below that applies to Windows 8.1 also applies to Windows 8.0 unless specifically differentiated.

The older revision of this page got extremely popular due to previous issues where I compiled a working convoluted set of workarounds that are no longer necessary, Microsoft have simplified their Windows Deployment and hence made installation of Windows 8.1 far easier.

Notes on Windows 10

Microsoft will release Windows 10 (probably in late summer) as a free upgrade to all Windows 8 and 8.1 users (providing they have upgraded to Windows 8.1 or clean installed Windows 8.1).

In order to ensure Microsoft does not make the same mistakes it made with the Digital Deployment of Windows 8 and Windows 8.1 go to this link and vote this idea up and share so everyone else votes it up.

Brief Introduction – Windows Licensing

Microsoft Windows 8.1 is sold via many different channels and there are a number of different activation mechanisms for Windows 8.1 depending on the type of license you are utilising.

There are 5 different license types:

In Depth – Windows Licensing

Major OEM License

The Windows 8.1 OEM license should be eligible for a free upgrade to Windows 10 for a promotional period of 1 year after its final release.

Because no installation media is provided for Windows 8.1 RT (a crippled version of Windows 8.1 essentially equivalent in functionality to Windows Phone) and Windows 8.1 with Bing or Windows 8.1 SL with Bing. I do not recommend purchase of any of these devices.

The Microsoft Windows 8.1 OEM licenses uses OEM 3.0 system locked preinstallation keys for activation. OEM 3.0 SLP activation inputs a unique 25 digit product key into the systems UEFI BIOS and hence has no need for a COA which have been removed due to piracy issues and due to the multiple problems users had when they peeled off or faded.

This part mainly concerns OEM product keys as there are more Editions and the product key (SLP key) resides in the UEFI BIOS. Many that will advise you on Windows installation on Microsoft Answers will say the choice is very easy and that there are only two “Editions” to choose from in accordance to your sticker and are wrong… there are actually 8 OEM editions users have made me aware of…

Unfortunately there is no way for the user to distinguish between some of these Editions and it should be stressed that are not interchangeable:

Windows 8.1 (Core/Home) ≠ Windows 8.1 N (Core/Home) ≠ Windows 8.1 SL (Core/Home) ≠ Windows 8.1 with Bing ≠ Windows 8.1 with Bing SL ≠ Windows 8.1 Professional ≠ Windows 8.1 Professional N

Home Editions

If you have this sticker which says “Windows 8” you likely have one of the following three editions:

Cora

  • Windows 8.1 Most Common
  • Windows 8.1 Single Language Common
  • Windows 8.1 N Rare

In the vast majority of cases the “Home Edition” is “Windows 8.1” or “Windows 8.1 Single Language”. If your system has this sticker try downloading these two .isos and if one of the .isos takes you to the license agreement during installation you have the correct “Edition”.

The “N” Editions are rare so try these only if the regular .isos don’t work.

Home with Bing Editions

I had a look at a few shops BestBuy, PC World, Staples in the US, CA and in the UK. I checked the sticker at the base of the system and compared this with the Edition in system properties. I was looking in particular for a difference in the with Bing systems. Although all the systems have a sticker which just says “Windows 8” similar to the other 3 Editions which the Media Creation Tool Supports it was a different sticker.

If you have this sticker which looks like the following you likely have one of the with Bing Editions which are unfortunately not supported by the Microsoft Windows 8.1 Media Creation Tool:

withbing3a win8bing

  • Windows 8.1 with Bing Most Common
  • Windows 8.1 Single Language with Bing Common

Pro Editions

If you have this sticker you likely have one of the following 2 editions:

Professional

  • Windows 8.1 Pro Most Common
  • Windows 8.1 ProN Rare

In the vast majority of cases the “Professional Edition” is “Windows 8.1 Pro”. If your system has this sticker try downloading this .iso and if the .iso takes you to the license agreement during installation you have the correct “Edition”.

The “N” Editions are rare so try these only if the regular .isos don’t work.

RT Edition

If you have this sticker you have Windows RT:

RT

A Windows RT device has hardware in particular a processor that is non-Intel/AMD using instead Arm processors. These devices were made to compete with Chrome Books as budget devices and prolonged battery life.

However in reality Arm processors do not scratch the potential of Intel/AMD processors because of the magnitude of third party applications written using either the Intel x86 or AMD x64 architectures (Intel and AMD have an agreement – Intel use AMD x64 and AMD use Intel x86).

These means the overwhelming majority of third party applications will run fine on Windows 8 but not on Windows RT. This gives Windows RT essentially the capabilities of Windows Phone…

This Edition was terribly marketed and sold often by shops as Windows 8. As a consequence of being sold and marketed as a broken variant of Windows 8 with the end user seeing it as a device with Windows 8 but with nothing working, Windows RT was highly unpopular. In turn as it was unpopular, developers never felt the urge to write programs which would run on Windows RT therefore making it redundant.

Windows RT is unfortunately unsupported by the Windows 8.1 Media Creation Tool and you have to procure installation media from Dell.

Determining Edition from System

If your system is working you can determine your Windows Edition and the easiest way of determining what edition your product key is for is by right clicking the start button (or pressing [Windows] and [x]) and then selecting system:

winx

Your Windows 8.1 Edition will be listed at the top.

Windows8.1SL

Determining your UEFI OEM SLP Product Key

The product key can be obtained using RWEverything but this is unecessary if the correct installation .iso is utilised from the Windows 8.1 Media Creation utility:

To find out the OEM BIOS Embedded System locked Product Key select ACPI Tables and the MSDM tab, copy down your product key.

rweverything

Note RW-Everything is the preferred utility to obtain your BIOS embedded product key because it will give you the product key regardless what version of Windows is installed. Other utilities can give bogus keys from the Windows registry.

For example this can be important if you have downgraded to Windows 7 and wish to migrate to Windows 8.1.

Legacy Issues with Installation Media

Important note, in the past Microsoft had a substandard deployment of both Windows 8.0 and 8.1 but listened to user feedback. Older installation media had the following problems and even if you have procured them from Dell I recommend never using them:

  • Discrimination between Windows 8.0 and Windows 8.1 Product Keys
    • Windows 8.1 media rejected 8.0 keys
    • Windows 8.0 media rejected 8.1 keys
    • Could be bypassed by use of Generic Keys and Change Key after installation.
  • Windows 8.0 involved a convoluted forced upgrade to Windows 8.1 via the Microsoft Store. This was problematic at best. The download is practically the same size as the full .iso.
  • Windows 8.1 media with this fault did not contain update 1. The update to update 1 was also problematic.

Use the Windows 8.1 Media Creation Utility to get Windows 8.1 with Update 1 Media.

Retail and Retail Upgrade

The Windows 8.1 Retail licenses should be eligible for a free upgrade to Windows 10 for a promotional period of 1 year after its final release. This is not applicable to Vista or XP licenses.

If you purchased Windows separately from your computer:

  • Windows 8.0 is “Upgrade Only”
  • Windows 8.1 is “Full”

However Windows 8.0 → Windows 8.1.

These licenses will come with a unique 25 digit product key affixed to the box with the installation media or were sent to you via email. Its recommended to email yourself a copy of the 25 digit product key in case you misplace the boxed media.

The Full version of the license can be installed and transferred from one computer to the other without any problems provided that it is only installed on one computer at a time.

“Upgrade Only" installation media as the name suggests only lets you install on top of an old Windows version. There are two main problems with this:

  • This method of installation always leads to detrimental performance
  • Many users have lost their installation media for their old license or didn’t get installation media for their old license if its OEM.
    • The OEM will be unable to ship installation media for the original Windows XP license as its reached End of Life.
    • The cost of procuring media for an out of Windows Vista system is higher than a new license.

It is therefore recommended you toss any Windows 8.0 installation DVDs in the bin. You may download a Windows 8.1 .iso using the Windows 8.1 media Creation Tool and this does not discriminate between Windows 8.0 and 8.1.

For the Retail Full licenses input your product key during installation and it should automatically activate online.

The Retail license is supported by Microsoft and not Dell. Dell may therefore not provide drivers for systems users have upgraded themselves but Windows 7 drivers will suffice in most cases. I have some additional notes mentioned here regarding system drivers:

http://dellwindowsreinstallationguide.com/driver-sets/

Windows 8.1 retail can be evaluated by use of generic product keys:

  • Core/Home=334NH-RXG76-64THK-C7CKG-D3VPT
  • Core/Home N=6NPQ8-PK64X-W4WMM-MF84V-RGB89
  • Core/Home Single Language=Y9NXP-XT8MV-PT9TG-97CT3-9D6TC
  • Professional=XHQ8N-C3MCJ-RQXB6-WCHYG-C9WKB
  • Professional N=JRBBN-4Q997-H4RM2-H3B7W-Q68KC
  • Professional with Media Centre=GBFNG-2X3TC-8R27F-RMKYB-JK7QT

OEM System Builder License

This is easily the most understood license because Microsoft’s intended use of the license was different to the bulk number of cases where the license was used.

This license is designed for smaller system builders to sell e.g. for local computer shops to purchase that build custom systems and sell them on to the end user with preinstalled Windows and installation media. Because such shops only sell a low volume of systems (compared to Dell or HP) there is no custom BIOS to include the markers for OEM SLP activation. The computer shop are meant to be the ones to support the license and since they can only support their own configuration there is the same OEM inability to transfer the license; it is tied to the original mainboard. The installation and activation for this license type is therefore more similar to a retail license. Phone activation may be required if Retail media is used for installation however.

In reality however it is seen by the end user as a cheap “Retail" license and users purchased it as it was significantly cheaper than the Retail Full or Retail “Upgrade Only" licenses. Experienced end users accepted that they got the license for cheaper and their only limitation was that they couldn’t transfer the license or get Microsoft support. Naturally less experienced users also followed this trend and didn’t understand the limitations.

Volume Licensing

The Volume License is essentially a volume “Upgrade Only" License although it can be utilised for clean installation.

The point is organisations purchase maybe >25 or more systems with OEM licenses from Dell. IT departments will struggle deploying custom Windows installations on possibility 100’s or 1000’s of systems with OEM licenses.

The Volume License gives them the flexibility to deploy Windows throughout their entire organisation without having to waste time phoning Microsoft to activate every system or separately clean install each system with a Dell Windows 7 OEM Reinstallation DVD.

If you are the end user, you likely have a dedicated IT department handling this. If you are the dedicated IT department and want to know more about it, then contact Microsoft who will give you a custom quote:

  1. Hello Phil, I’m trying to do a fresh install of Windows 8 Single Language. Can I use my product key on a 8.1 Single Language? Will it work?

    1. Yes this downloader now accepts Windows 8 and Windows 8.1 keys as equal unlike previous flawed downloaders.

      The Windows 8.1 Single Language .iso will work with Windows 8.0 Single Language OEM/Retail key.

  2. To one of the experts, I want to downgrade from win 8 to win 7 (Ult) on my laptop. I have win 7 disk.

    1. It is not worth your time downgrading from Windows 8.1 to Windows 7 Ultimate (via a full retail license) at this stage. In Late Summer Windows 10 will be released and Windows 7 and 8.1 will both be auto-updated to Windows 10 as a free update. Using 2 Windows licenses for a system to get Windows 10 is not worthwhile and its not worthwhile performing the downgrade for only a “few” months use. Both Windows 7 and 8.1 will be realistically obsolete once the majority of the userbase has migrated.

      Windows 8.1 can be made usable with the following settings which should get you by for they few months:
      http://dellwindowsreinstallationguide.com/a-clean-install-of-windows/a-clean-install-of-windows-8-1/customising-windows-8-1/
      You can install Windows 10 Technical Preview at present but should be aware that it will have bugs.

      There is also the fact that Dell are not providing new Home Inspiron systems with Windows 7 compatible drivers so you may get limited functionality in some cases. You have to make some adjustments to the UEFI BIOS setup such as disable SecureBoot, enable UEFI, convert your installation media into FAT32 UEFI Bootable media for the GPT partition scheme, enable USB Debug (disable USB 3.0 functionality) in order to accomodate a Windows 7 install. Windows 7 has >200 updates to install so updating takes longer than the Windows install.

      If you wish to proceed with the downgrade (not recommended) you should at least provide some basic information such as the model and post on the Dell Community Microsoft OS Forums opposed to the comments here:
      http://en.community.dell.com/support-forums/software-os/f
      If the system is a non-Dell use Microsoft Answers:

  3. sir my windows does not show activated after i use data recovery function by pd …………………..
    and i created this recovry from my new lappi so why this not showing activated sir plsss give me any solution as soon as possible

    1. Explain what you did in detail, provide model number, version of Windows and its better to post on the Dell Community Microsoft OS Forum opposed to the comments here.

  4. I INSTALL windows 8.1 core edition but the key you provided is not working and when i try to activate its not working either
    what to do please . i have laptop acer

    1. Do not use generic keys for an OEM license. If you are prompted for a product key with that .iso you have likely selected the wrong Edition. See here:
      http://dellwindowsreinstallationguide.com/download-microsoft-windows-and-office/download-microsoft-windows/download-windows-8-1-retail-and-oem-iso/
      Try Windows 8.1 and Windows 8.1 Single Language. The correct Edition will not ask for a product key and take you straight to the license agreement screen. The incorrect edition will ask for a product key.

  5. Does updating windows from 8 to 8.1 changes the OEM product key in BIOS? I am asking this question because I’ve got 2 directories in windows registry, viz., “HKLM\Software\Microsoft\Windows NT\CutrrentVersion\DefaultProductKey”, and “HKLM\Software\Microsoft\Windows NT\CutrrentVersion\DefaultProductKey2”. But I don’t know if they were already there before updating windows.

    1. The product key in the UEFI BIOS cannot be changed via software as it would be a disaster if it could.

      Updating from the store sometimes gives you another key which is useless and hence throws out many programs which look to the Windows registry for the product key. Its a reason why I recommend RWEverything which looks at the hardware and not programs like Berlarc Advisor which look at the registry for the product key.

  6. Hello, i have just bought HP new laptop After 2 weeks i get warning tht yur window is going to expire insert yur prouduct key. Currently i have window 8.1 single language and i cant find it product key. Plz send product key

  7. Help me
    I have an acer laptop the sound drivers and usb drivers does not want to read anything
    what should I do

  8. I have a Dell latitude 3540 which I bought secondhand, It came with Windows 8. 0 Enterprise, which I couldn”t be updated to 8.1. When called Microsoft and gave the key from the Bios, they said that it was an legit key, but that it was for Windows 8. pro. They even sent me a reinstall disk for 8.1 (I paid $15 for it.) But when I tried to use it, it wouldn’t accept the key. And when I called Microsoft back, they said that that’s because it’s a dell machine–I told them it was dell machine before I bought the disk–and that I needed to call dell to activate it. So when I called dell, they refused to sell me a ‘usb key’ which they implied would solve the problem, because I couldn’t give then the proper information about the previous owner. (The machine was still under warranty.) They asked me to fill out a form and then made me wait a week. Anybody have any ideas? I really don’t want unupdatable 8.0 enterprise, which Microsoft say doesn’t exist, on this machine. Is there any way I can get back to 8 or 8.1 pro without buying a full license.

  9. Thanks Phillpyip, I’ll have a look. There’s a new wrinkle. Dell won’t send me a reinstall disk, but they say that this computer was downgraded to Windows 7, and so that the key that I have should work for Windows 8 or 7. Is that possible? I was told that if I can get a hold of Dell reinstall disk or usb for 7 or 8, that it would work–and not even ask for the key. Is that right? And won’t I have to get Microsoft (by phone) to activate it after the install? Who to trust.

  10. I have purchased a dell laptop with Ubuntu out of the box and I installed windows 8.1 but that’s pirated and I didn’t get dell branding.Please provide me 8.1 dell oem ISO with all dell branding

  11. The question is. My computer was supplied with OEM (Dell) Win 8.1. I was so P`d off I reformatted and loaded Retail copy of Win7. However I have upgraded the win 7 on to my wife’s Vista computer.

    In theory I STILL have a valid Win 8.1 entitlement to and upgrade to 10. How do I access it?

    Pete

    1. You download Windows 8.1 and reinstall it. The main difficulty is determining the correct Edition:
      http://dellwindowsreinstallationguide.com/download-windows-8-1-retail-and-oem-iso/
      After Windows 8.1 is reinstalled you can upgrade to Windows 10 TH1:
      http://dellwindowsreinstallationguide.com/upgrading-to-windows-10/
      The upgrade to TH1 requires an upgrade install unfortunately. You could of course upgrade to Windows 10 TH1 using your current Windows 7 license but its a waste of a license; better to consume your Windows 8.1 OEM license for the Windows 10 Upgrading freeing your retail Windows 7 Upgrade license for your older machine.

      If you don’t have a Single Language or Bing Edition of Windows 8.1 you can upgrade to Windows 10 TH2 beta:
      http://dellwindowsreinstallationguide.com/download-windows-10-technical-preview-iso/

      TH2 is much better than TH1 and will allow for a direct Clean Installation. My advise is to wait until TH2 is out on the main track before upgrading to Windows 10.

  12. HI,
    Forgive me if this question was already answered.

    I have a dell Inspiron 7720 laptop purchased second hand with a failed hard drive.
    I dont have the original windows 8 key that it came with. I also was unsuccessful retrieving it from bios using software like rwEverything, etc.

    I cant get OEM installation media from Dell because this computer is not registered to my name and I cant get in touch with the original owner anymore. Frankly, dont really want to pay for the installation media anyway.

    Is there a way for me to find out the original windows 8 key? that I could then use to perform a clean install of windows 8.1 and windows 10?
    thank you

      1. No MSDM tab means there is no Windows 8 or Windows 8.1 OEM UEFI BIOS Embedded SLP key. Even if you got Reinstallation Media from Dell it wouldn’t work…

        The official answers are either 1. Because the key is classified as part of the hardware you need to either replace your motherboard (if in warranty get Dell to do so) or 2. Buy Windows 10 as a Retail License.

        Some of the 7720s would have been old with Windows 7 and not Windows 8 or Windows 8.1 and hence will not have a MSDM tab however so look for a COA under the battery just in case.

        If you have no MSDM tab and no COA unofficially you may try this workaround:
        http://dellwindowsreinstallationguide.com/windows-xpvista-%e2%86%92-windows-10-free-upgrade/

  13. Thank you for your quick replies.

    There is still an official windows 8 sticker on the back.
    As well as a plane white sticker with partially faded “Product Key” that looks like a windows key to me. I cannot decipher some of the characters in it though.
    I also read in other forums online that Dell laptops (at least a few of them from the sound of it) don’t seem to have MSDM tab and tools like RWeverything fail to work.

    Anyway, thanks again.
