As of this writing, the version of Windows 10 has switched from RS Pre-release to RS2 Release branch, i.e., it has entered the phase of RC. In other words, Windows 10 operating system has formally stepped into to a comprehensive upgrade & update stage.
After entering the RC phase, Microsoft actually has finished the development of all new functions. The future versions will focus on bugs fixing and performance improving, hardly any new function will come out (the exception is those internally approved but not announced features, which is rare).
KMS Win10 (AKA: Win10 Activate, Win10Act) is an online activation tool for Windows 10 RTM releases, comes with compact UI and simple operation. It can keep all editions (primarily Professional Edition and Enterprise Edition) and all versions of Windows 10 permanently activated.STRONA DOMOWA
