Its working only for Windows 8 phone activated with retail key systems.
Press the Windows + R keys and type services.msc and then find Software Protection and click the stop button.
easy way run in elevated command prompt "net stop sppsvc"... Thanks for new way of activation, will test it...
I got lost here: 1.Backup your activation with Windows Advanced Tokens Manager How do I do this? Thanks.
sorry, now even i am confused i dont think you can activate win 8.1 completely offline, you need to use either phone or online, just that a valid *.dat file will allow/accept your wmc key and activate it either way.so i believe OP meant to say online activation is possible. ps: even for this method to work a previous *.dat file should have a retail key connection [ my guess } @op can you say weather your windows 8 pro was retail actvated?
