    Right, the whole data.dat thing seems to be a bit of a concerning mystery. I've obtained a couple of these files and binary compared them; none have been the same size, here's where it stands so far:

    • ambidav: 18kb - unknown creation method
    • FaiKee v1: 24kb - unknown creation method
    • FaiKee v2: 24kb, installed and activated with KMS, changed to MAK key and reactivated, Pro WMC applied and activated
    • Mine: 16kb, installed and activated with upgrade retail key, WMC key applied and activated

    Now the interesting thing is that whilst the majority of the file is completely different (I assume encrypted based on HW ID), there are common markers between mine and ambidav's file. The odd thing is, his is 2kb longer.

    What I'm looking for, from you guys, is your self-created data.dat files, along with details of your creation scenario. I want to find out if there's a specific difference between KMS installs, MAK installs, upgrades from Windows 7, and Core --> Pro --> WMC scenarios.

    The purpose of this is to determine whether or not Microsoft would be able to detect exactly what method you'd used to activate, and revoke your activation in future if using an "unsupported" method (ie, one that goes against the EULA).

    If you could attach your data.dat to this post, that'd be brilliant. Cheers!

    Updates:

    04/11/2012, 09:32 - FaiKee posted a second version of his data.dat, apparently the first was from his friend; this, too, is 24kb and was MAK-activated. This file, again while being largely different from the first 24kb version, has common markers in the hex throughout the file all the way to the end. If someone else with a MAK-activated + ProWMC setup could post their data.dat, this would go a long way to confirming a 24kb data.dat for MAK copies.

    04/11/2012, 12:15 - Just did a fresh install using KMS activation, 11kb data.dat; applied WMC key and installed without activating, data.dat became 15kb. Now testing the installation of WMC using the public WMC key, and will check the size and then test that in a slipstreamed ISO to see if that allows installation and activation using the free WMC key. Overall, this seems like the safest way, as it doesn't tie you to any identifiable issued key, retail or otherwise.

    My data.dat is also has different size. It's 52KB (size on disk). I Upgraded W8 from W7, activated with KMS server, add WMC and activated again with free WMC key.

    Ok my findings...

    windows pro activated KMS = 11kb
    Windows Pro activated Kms with WMC added and activated = 20kb
    Windows Pro activated Kms with WMC added plus office pro retail = 29kb

    mdc: seeing all these datas I think I have to give you more details:

    actually my win8 was first KMS activated from the first leaked Russian host in Aug., then later MAK-activated, I also have a MAK-activated Office 2010.

    As for my friend, he is MS guy, but I don't believe he gave me the data.dat from his personal key win8(not a chance LOL :D), these guys have their resources.

    Oh Christ, this is getting more and more messy haha. I'm gonna install Windows 8 and KMS activate it, then install WMC and capture the data.dat before activating.

    I don't think Office 2010 touches SPP; instead it uses its own store located here: C:\ProgramData\Microsoft\OfficeSoftwareProtectionPlatform\tokens.dat, so I think we can assume 24kb for KMS + MAK, or possibly MAK by itself. Any volunteers to do a clean install with their MAK key? :p

    I'm hoping KMS + WMC (unactivated) comes out at 18kb, as that would explain ambidav's size, with an additional 2kb post-activation to match Nick's.

    If you could attach your .dats that'd be great Nick, as then I can hex compare them and see which pattern KMS follows; mine or FaiKee's.

    No effect.. Office 2010 uses its own protection platform even in Windows 8.

    ;) :D

    Ouch, that's huge lol... I'm guessing 2013 added quite a bit to that, as it uses the SPP store as well.

    I found my data.dat file with a size of 19kb using enterprise KMS activated and office 2013 with technet key on 32 bit version and same size on a 64bit machine.
    On another 64 bit machine, I activated 8pro with a MAK key and find a size of 16kb

    I don't think size matters LOL - Correct me if i'm wrong but I think the OP wants to compare the data in dat file :p

    So perhaps just upload and name it like KMS+WMCx64 or Upgrade+WMCx86 or something...

    Right, here's an interesting little bit of information; I installed Windows 8 Professional x64 from the upgrade ISO twice, both times using the KMS key, activated both times using the same public server, and both times resulting in a (roughly the same) sized store.dat of 11kb (11,040 bytes and 11,072 bytes).

    The contents of the files are completely different. There are, however, the common markers throughout the extent of the file which I noticed previously with both FaiKee data.dat files. It seems that the encryption of the file is ridiculously complex, and could take any number of factors into consideration; hardware ID, timestamp, products keys, etc etc. It would make sense, as this file (along with tokens.dat) controls your activation status, and is so central to SPP in general.

    The one thing which seems pretty clear, however, is that the more steps in your activation, the larger your data.dat file. With this in mind, I've collected a 14.5k (14,864 bytes) data.dat file, created by installing using the generic ProVL serial, activated by KMS, and then installing ProWMC using the generic ProWMC Retail serial. If this works, it should provide the least trackable method of doing a clean install of ProWMC using the free keys.

    This does not work. When you upgrade to WMC with the Retail key, the necessary data isn't inserted into data.dat that would allow it to accept WMC upgrade keys. So far, it seems the only way to obtain a data.dat that does accept WMC upgrade keys is to apply an upgrade key to a Pro without WMC. I have tested this several times. I would also prefer a "clean" data.dat, but so far have not been able to find a way to generate one that accepts upgrade keys.

    ... crap. Well I suppose I'll find out for myself in about 8 minutes, just copying the sources to the USB stick now haha.
