    Determining Windows 7 Product Key

    Our PCs and laptops would usually have the same Windows 7 Volume Licence product key.
    However, because of purchases of additional licences over the past few years, the product key which was given for each batch might have been used instead of the 'main' one.
    Furthermore, it is possible that the product key which came with the PC or laptop might have been left unchanged.

    My usual standby for determining the Windows product key, namely Nir Sofer's Produkey, cannot determine the product key for Windows 7 and above, because (he says) that the information is no longer stored in the registry.

    Does anyone know of some software which would enable me to determine the activated product key for Windows 7 on each of our devices?

    You could try either of these two cmds - http://www.thewindowsclub.com/find-windows-product-key but I generally use either Belarc Advisor or Magic Jellybean, but with an OEM machine, they only give the vendor's generic key which won't activate a retail/repair install.

    EDIT - Perhaps not - the cmd prompt cmd returned an Invalid query on my OEM Win 7 and the Powershell cmd just gave me the next prompt without returning any info.

    There's a useful link in the article which will give you these -

    BATcher,

    It depends on who you want to believe!

    For my Win 10 Pro (upgraded from 8.0, 8.0 Pro, 8.1 Pro Media Center Ed.) I get a variety or results depending on the method used:

    Windows Own service level manager (slmgr.exe)
    WinLicShort.PNG
    As you can see it only provides the last 4 characters but unfortunately those are the numbers for the Windows 10 Insider Preview upgrade!

    Of course Belarc Advisor can be even more confusing:
    Version 8.4 results
    Belarc8-4.PNG
    Windows 8.1 really!
    Version 8.5c results
    Belarc8-5c.PNG
    Well at least now they have the version correct!

    BTW: this is the number used on the Insider Preview installs and I never installed the Preview on this machine!

    Speccy reports:
    Code:
    Operating System
    	Windows 10 Pro 64-bit
    	Computer type: Desktop
    	Installation Date: 2/5/2016 6:21:55 PM
    	Serial Number: xxxxx-xxxxx-xxxxx-xxxx-HCFC6
    Now we're getting somewhere! Speccy actually provides the whole key but I edited it.

    My homegrown PowerShell program reports:
    Code:
    Item                      Value                                                
    ------                    -----                                                
    OS Name                   Microsoft Windows 10 Pro                             
       Version                10.0.10586                                           
       Bit-Width              64-bit                                               
       Key                    xxxxx-xxxxx-xxxxx-xxxx-HCFC6
    Again edited but it is the number I have recorded in my RoboForm note that contains all my software and license numbers.

    So who do you believe?

    BATcher,

    I forgot to mention that on my Win 7 HP laptop all the products (Speccy, Belarc, slmgr) report the same number! HTH

    That slmgr -dli cmd doesn't produce anything on my Toshiba Win 7 laptop - are your installs retail, RG ?

    EDIT - Oh yes it did - just took its time popping up but it's just the last digits of Toshiba's generic key.

    Thanks, Jerry - but without trying it yet I suspect that it will fail in the same way as did Produkey - the Windows 7 product key is not stored in the registry.

    But I will try it!

    Wow, this is going to be an issue for a while.

    https://sourceforge.net/projects/laz...dowskeyfinder/ - claims it supports Win10...but doesn't say it retrieves the key. Let us know if it works.

    edit: second screen shot in the above link shows it returning Win10 TR product key. So likely it works!

    F.N.,

    Seems to report the same as the others, at least for me!

    I've just worked through all the suggested programs for finding the Windows 7 Volume Licence product key, and can report:
    * I got the same results as Sudo15 with the WMIC and PowerShell commands, namely error and nothing respectively
    * Speccy gave no product key information at all
    * Belarc said the the key ends with VWXYZ, the same as slmgr -dli A footnote says "The full product key is not stored on this computer."
    * Magical Jelly Bean says that "in the demo, the full product key is hidden", but I don't want to spend $30 to find out if it can or cannot find the full product key
    * Lazesoft give the product key as BBBBB-BBBBB-...

    So it looks as though I can only the get final five characters of the product key, the simplest way being via slmgr, which I can't use in a BATch file since a windows comes up which I can't process.

    Thanks to all for suggestions!

    I have never had Belarc Advisor not list the full product key even on a Windows 7 volume license. I am even typing on a Lenovo Win7 laptop now and just checked with updated Belarc Advisor to see if anything had changed and it reports the full product key from the vendor license (as opposed to the product key required to be present as a COA on the laptop).

    So I have to wonder if the UK or EU requires or the major makers practice not putting the full vendor product key on the machine as some sort of copy protection to keep people from creating a vendor license installation disk. If that is the case however, I am not sure why they would not do it in the USA. I'm not sure why since you cannot do a whole lot with a vendor license product key unless you have a copy of the original installation disk and the desire to slipstream an updated disk. It isn't easy to make a working disk--you make a lot of coasters before you get it right--but doable using instructions on the net.
