FOG Client / FOS report bios product key to database (Host) Activate through BIOS key (Deployment)

x23piracy

Hi,

i really would like to see the fog clients ability to read out the current windows key and report it back to the fog server, this information should then be added to each specific host definition.

When i first deploy a new computer, i use my tool setkey.exe as a snapin, this will activate the machine with it’s bios embedded key, if the fog client could report that key i can deploy the next time with the exact key instead of usage of my snapin: https://forums.fogproject.org/post/99211

That combined with a new report, “key report” would complete it.
My birthday is at december, 16th. so enough time

What i cannot tell you is howto read out the bios key, i have tools for it but i don’t know howto do it yourself, for example if you use nirsoft’s key view there is a difference between the bios and the current registry key:

Every Win 10 that was activated by a bios key is showing the VK7JG key in its registry.

Additional another tool that can read out bios key:
https://github.com/Superfly-Inc/ShowKeyPlus/releases
(but it seems the source is missing)

Another python script: https://github.com/iamacarpet/win10-autoactivate/blob/master/activate.py

Edit2:

Maybe this: https://github.com/mrpeardotnet/WinProdKeyFinder/tree/master/WinProdKeyFind
but i haven’t tried if the code is working. (Damn only registry)

What i cannot tell you is howto read out the bios key, i

Why not start by helping us and doing some research if and how this can be done using .NET C#…

x23piracy

@sebastian-roth did so check first post but it’s python.

x23piracy

@sebastian-roth i am finding a lot of tools but non where the source is available and if so it’s not in net c#

Sebastian Roth

@x23piracy said in FOG Client report Windows key to FOG WebIf (Host definition):

… GetSystemFirmwareTable … EnumSystemFirmwareTables …

Looks like those calls are available in native C++ (ref1 / ref2) and AFAIK using that from C# is possible (ref3).

But I am wondering if that is really the way to go to get that key? Can anyone confirm this is really working using the python code?

x23piracy

@sebastian-roth yes me, because that python code is part of the binary i use for my snapin, it works great.
i am using the exe binary: https://github.com/christian-korneck/get_win8key

from a system without key in the bios
Bild Text

from a system with key in the bios
Bild Text

i just bypass the output of that binary to slmgr /ipk key and then trigger slmgr /ato, thats it.

@echo off
for /f “tokens=*” %%i in (’%cd%\oemkey’) do set oemkey=%%i
cscript %systemroot%\system32\slmgr.vbs /ipk %oemkey% >nul
cscript %systemroot%\system32\slmgr.vbs /ato >nul
exit

Sebastian Roth

@x23piracy I am still not sure if I get this right. Should we also extract the key from the registry if we don’t find it in the firrmware table? What if we find both, what if they don’t match (is this possible)??

If we find both, we take the one from bios, if only registry found we take this.
They will never match a windows 10 pro bios activated computer always has the following generic key in it’s registry:
VK7JG-NPHTM-C97JM-9MPGT-3V66T

since i know that u are german: https://www.deskmodder.de/wiki/index.php/Seriennummern_Key_generischer_Schlüssel_Windows_10

Additional to the feature request itself, it would be a really cool if we could embed the activation with what i am doing with my setkey.exe snapin into fog, so under host definition could be a checkbox near the windows key labeled “activate with bios key”. That could be checked by default, so if i deploy a new computer fog will automatically activate with the bios key and the fog client will report the specific bios key back to fogs host definition and if there would be a report the pakage would be complete.

For the client interval how often to check the key i would recommend to only do it on first client checkin, we just need to check this once, the key will never be changed. so if we once collected a key from a specific host we can stop crawling the key for it. Maybe it could be useful to have a function to say he try to recrawl the key for that client without resetting this for all.

Maybe we also need a global option for the fog client: “Report Client Windows Key” @tom-elliott

As i can see we still have a product key report

Hi,

i’ve got a ps cmd line that offers the bios key in one single line.

Powershell

(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

Commandline

powershell -Command (Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

Activation in one line with powershell:

slmgr /ipk (Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey ; slmgr /ato

returning messages should be send to nirvana

george1421

@x23piracy I’ve been lurking on this thread. Isn’t the goal here to be able to read the key from bios using linux? (BTW, your PS code is pretty sweet!! Nice job)

I think I found something–>

To get it, you need to read the contents of the /sys/firmware/acpi/tables/MSDM file.

Here’s an example:

riking@hp-laptop:~$ sudo xxd /sys/firmware/acpi/tables/MSDM
0000000: 4d53 444d 5500 0000 0313 4850 514f 454d  MSDMU.....HPQOEM

@x23piracy @george1421 I was just about to create an issue on github (which I use to keep track of things I work on with the fog-client) for this request as I had the impression that it’s worth and doable. But Georg’s post now suggests that it can be done from Linux, so on the capture/deploy process in FOS. Now I am wondering which way to go. Please keep discussing this here till we decide how and where to add this (fog-client, FOS, …?).

x23piracy

@sebastian-roth @george1421 if you are able to inject the key like slmgr is doing that with (/ipk and /ato) on a running windows system why not doing it in the moment of deployment under FOS. I like the idea, but how can you inject it?

If we have this feature in the client we have to think howto implement without polling this information again and again, we need it only once so i think the FOS method would be the best if you can do it.

Here is the slmgr.vbs: https://pastebin.com/a2yP1MfD

But remember we should not force to use a bios key if available maybe we have cases where people use Volume License (KMS Server) while they having computers with BIOS key inside (ok would be stupid) but i am sure this case is existing. So we need a switch or something in the host definition to turn on/off activation with bios key.

But what if we have a allready installed system that wasn’t deployed by FOG, i really like to gain such keys after the installation of the fog client. Maybe we need both FOS’s ability to inject and detect a key and the same with the fog client for existing computers that naver had contact with FOG but going to have FOG Client installed on it.

Challenge accepted?

EDIT:

I have the feeling we need to write to the windows registry under FOS if we would like to inject the Windows Product Key:
http://www.dagondesign.com/articles/windows-xp-product-key-recovery/
http://geekswithblogs.net/willemf/archive/2006/05/31/80203.aspx

I am not sure but maybe we don’t need (slmgr /ato), windows should activate automatically by itself.

The more i think about i came to conclusion that the mechanism of reading and injecting the key should done by the fog client, while the system is running.

What do you think guys?

Regards X23

george1421

Well we have to remember or be sure to create an isolation between FOS and the target OS. For windows activation that needs to be done inside windows. Either through the unattend.xml file or slmgr or fog client.

What would be interesting is if / when FOS takes an inventory of the target computer it could also read the bios key and store it in a field. Maybe not the activation key field but a bios key field. Then at some time that bios key may be copied to the activation key field and let the fog client do its thing. OR within the FOS post install scripts to be able to have access to that information (via the gethost.php script) so the post install script can use it to update the unattend.xml or patch a setupcomplete.cmd line that runs the slmgr command. But the idea is that if we collect this during inventory then I don’t see any other bits of fog needing to be changed other than adding a field to the inventory table, making that new field visible in the webgui and changing the inventory script to collect the key.

I can’t say for sure that the stuff that I found works. My Linux Mint laptop is built for Win7 so there is no key to be found when I inspect the MSDM table.

FOG Client should trigger slmgr with the apropriate key from the database.

Yes, i think thats the way to go but what if someone uses FOG in an already deployed but growing environment. Typically FOG Client would be mass installed, is the FOG Client reporting the same inventory stuff like the inventory been done by the boot menu? If not FOG Client also should have the ability to read the key from bios and report it.

Why not keeping it simple? Would it not be enough if the fog client checks if the client has it’s key and if not just trigger slmgr with the information we have in the db?

I can’t say for sure that the stuff that I found works. My Linux Mint laptop is built for Win7 so there is no key to be found when I inspect the MSDM table.

I tried this with my work pc over the ubuntu bash windows 10 offers, there are the acpi tables missing but i think that have to be done in a native running linux not in an emulated one.

@george1421 can i try your usb FOS Image, maybe boot from the stick and try if i can get the serial from bios?
Lets say that works can’t we start with sending that key to fogs database for the current product key field? If this has been done we are good to go because currently fog client can activate a deployed system by an entered key in that host definition field.

I agree, but that is where your handy code comes into use. That can be integrated into the {next} fog client to update the bios key field if the developers see value in it.

Yes that should work well. I forgot about that method of booting. There is a debug mode built into that usb stick. So it is pretty easy.

Lets say that works can’t we start with sending that key to fogs database for the current product key field? If this has been done we are good to go because currently fog client can activate a deployed system by an entered key in that host definition field.

The risk here is replacing a MAK or KMS key with the bios value may not be what all users consider useful. That is why I picked a new field, so it is stored. Then a crafty IT admin could write a simple mysql command to copy it over if its blank. I’m not seeing this as a widely used feature. But a useful one if you need it.

x23piracy

Yes it works,

i just created a FOS USB Stick, thank you @george1421 and booted it with a notebook that has a product key in it’s bios into kernel debug mode (i need shell).

Then i entered the following command:

tail -c+57 /sys/firmware/acpi/tables/MSDM

What i got was, surprise a product key:

Bild Text

To be sure that this is really our product key i also used the command i found and a key tool to crosscheck the key.

And yes it’s correct:

Bild Text

What we need now is the following @Sebastian-Roth:

FOS ability to read and report bios product key to the host product key field in db (expand the inventory script with the command above to read the key and report it like any other inventory item)
FOG Clients ability to also report product key (if not already done) for the case if the fog client has been mass deployed in existing environment where maybe not all host will be booted and inventoried by the FOG Boot Menu.

Afaik this should be all we need because if i fill the product key field of a host today with a product key and deploy a windows system, fog client will set this key into the system. So everything is prepared except the feature that we can read key from the bios and report them to the db.

Who is responsible from the dev team for the FOS?

Regarding to @george1421 post before, another solution could be a second product key field, one is for the manual known input, and another for determined bios product keys, now for each host there could be a switch in the options where we can decide which product key field to use?

Am i wrong?

Regards X23

george1421

The more I think about it, the less I’m inclined to say this is a needed feature. While its technically possible to add this to fog. I don’t see the value in having the devs spend their time to read out and store the bios activation key. That key is only of value to activate OEM images. The only way the OEM image can be deployed is via the original media is was delivered on. With OEM media you are not allowed to install, alter, capture and redeploy an OEM install. It may be only installed from the original OEM media. That process is not the intent of FOG Project.

For FOG Deployment, when you are deploying Windows OS, you must use a Volume License key. These can either be MAK or KMS keys. You can pick up a single VLK license per OS you need to distribute . That is just one license per OS, you pay the same price for the VLK for 10 systems or 100 systems. The only caveat is to buy into the open program you need 5 MS points, the VLK license counts as one. What some people have done is purchased the 1 VLK licenses and 4 network CAL licenses to reach the 5 count.

When I get onto my other computer I’ll post a link to a post on Spiceworks that talks about what you can and can’t do (legally) with imaging MS products.
[update]: Here is the link I mentioned above https://community.spiceworks.com/how_to/124056-reimaging-rights-for-windows-10-licensing-how-to

So I think if I had a vote, I would rather have the devs work on this unable to read inode from library issue than spend time adding a feature to FOG that only a limited number of people might use.

x23piracy

for me it’s hard to follow that position. But i have to respect it.

x23piracy

Hi,

can i have some clues where is the right point to try to embed the command while doing an inventory? which file in the filesystem is doing all the commands while doing inventorisation?

If the team isn’t willing to integrate, i will do it on my own.
