No. I was flagged non-genuine after running slmgr -ato on a kms/retail data.dat-wmc machine, no matter how many data.dat files I tried how many times. But if it pleases you to hear "I would not be comfortable", I'm cool with that.
Well as long that the KMS activation is stored in your dat file, your gonna be flagged as non genuin. Dont know if it works, but remove dat and tokens, rearm and reboot. Than ipk retail key and activate online and WMC upgrade.
Thanks but done that and still non-genuine. Will stick to pure kms for now and maybe try out server 2012 later with Daz's loader. Or maybe hopefully Cody will be able to randomize the ePID and make us all unfindable with kms activation.
The guy says that the activation date could be changed at will; but he did not say how(maybe later). I don't think there's practical use, just for fun.
Search the webs for KMSNano. MDL guy heldigard has consolidated the hard work of the KMS server emulation people and created a nifty lil activation routine. I don't understand all of the terminology fully but basically it emulates kms activation in memory by using a virtual machine. His latest version is only like 40 megs. Came out today IIRC. lananov10.zip I believe. Typical usage would be to extract it and run the convert_windows_retail2vl.cmd and then run the kmsnano.exe. If the convert_windows_retail2vl.cmd doesn't run, use Fix Hacktivations.cmd and run kmsnano.exe
0xC004C4AA is the error you want. If you have any other error, it will not work. you run the commands in admin command prompt
