yep i do expect that - too was just wondering what everyone was posting, so decided to have a play and see...
It makes sense though, why would anyone with a KMS activation activate a WMC to retail ?. Secondly i don't understand Microsoft either, they offer a free MC key to everyone with a email adress, why don't they ask for the retail pro key for sample to offer the free upgrade to users who actually paid for it. From a big company like that they are not that smart.
may be they have something back in their mind, they have been doing this from the very first day, the gave the 14$ upgrade key without the windows product key check then implemented validation of product key now , so no wonder they may implement some sort of check for the WMC as you say
tonystark, please specify *which* data.dat method. (1) The "clean" data.dat (that's KMS activated) or the (2) "WMC-key activated" data.dat? I can also confirm (1) don't work no more, testing (2) right now.
OK, please forgive me my stupidity but I just want to have something confirmed: When I take my retail Windows 8 Pro DVD and convert it to Windows 8 Pro with Media Center using dism /image:<path> /set-editionrofessionalWMC and do the clean install, the activation will not pass. Is that correct? Because I did it last month and it worked flawlessly. The activation is still valid and the system working. If the above doesn't work anymore, will my installation be usefull for some kind of activation backup or so? What should I do with the data.dat file? Thx.
The way I understand it MS now allows activation of WMC keys only within Win8Pro and checks the previous license. Do you think MS backed up all licenses while activating WMC keys and then will revoke all those bad activations? Those keys are legit, I don't think MS can afford to blacklist them since then it would be impossible to activate it using 100% legit way (install Win8Pro, upgrade to Win8Pro with MC). Of course, I can be wrong.
This only will become a problem, when new WGA check arrives. Then some more solutions will become useless.
As it seems so far, the process checks the last five digits of previous key. Should be enough to classify a non legit activated system and refuse the WMC upgrade.
