Refer here (to know more about Windows 10 KMS activation)
To activate Windows 10 all versions:
When you install the Windows 10, it will ask you for key, and ;
THERE IS A SKIP BUTTON ON THE BOOT SETUP FOR KEY ENTRY. DO
NOT COMPLAIN ABOUT ENTERING A KEY. PRESS SKIP EVERYTIME II ASKS YOU FOR A KEY !
You can use Microsoft Toolkit 2.5.3 (torrent link from MDL forums) to activate your Windows 10 and use all features of it. While KMS activators (like Microsoft Toolkit) do work, but we don't recommend them as they set your Activation channel to a default MAK (Multiple activation keys) and MS (Microsoft) likely knows the difference. They could kill that activation later with a WAT update.
For permanent activation I recommend you to upgrade from 7 or 8, but the system has to be activated and not the Enterprise version of Windows 7 or 8. I recommend Windows 7 Pro/Ult activated with WinLoader (Daz Loader) to upgrade to 10 Pro though Windows Insider Program. Make sure your network connection is online during upgrade or the activation will not happen. After successful upgrade and system showing activated, then you can re-install from boot (a clean install) by downloading Windows 10 of your choice from below links and it should (automatically) re-activate from MS servers. It reads your hardware info, not key. Key will be generic for this upgrade offer of Windows 10. Do not try to enter one during boot setup unless you bought Win10.
All the activation Information source: Murphy78 from MDL forum !

This is the same build that was sent to OEMs. It is RTM.
It is also the same build that is on MSDN. The only differences are the version and ISO structure/compression. ( Convert ESD to ISO refer here )
