download & install Win 10 Build 10162, Activate Genuine for Life long

hi guys, I need your help, if I install windows 10 Pro 10162 and successfully Activate with the key Microsoft provided.

1-Is this Windows 10 Activated for ever LIFE LONG.
2-And if I format after 6 months my PC, and when I reinstall win 10 Pro on the same Genuine win 10 PC, is this going to REACTIVATE or not. I mean it is going to give me a trouble, like by saying "windows is not genuine ETC"
Usually when we have DISC of Windows FORMAT & REINSTALL 1oo times on the same PC, it will accept the same KEY with out any problem, please make me clear "what kind of genuine activation of windows 10 we have currently"
3-if I Activate windows 10 pro build 10162 Genuine by Microsoft currently, after 6 months when I format my PC I will install Windows 10 Pro Latest Build with the same Key, so it will be Re-Activate again with out any problem, please let me know.
I mean my Bother Board already Registered in Microsoft Account when I install Win 10 Pro Build 10162, once it is registered then any newer version windows 10 can I install with out any problem like a GENUINE always. please let me know.


Thanks for your replies.

1 no it is a beta pre release version and will time out in less than 6 months.
2 In 6 months there will be retail versions of Windows 10 to buy, which will be genuine. If you already have genuine Windows 7 or 8, you will be able to upgrade them to genuine Windows 10 versions or clean install thereafter.
3 10162 has already been superceded by a later build, so do not bother with 10162 any longer.

If you have a Microsoft account and register on the Insider program, It will be possible to run Windows 10 on your account after the RTM version has been released essentially as a rolling upgrade - so it will always be activated - whether the concept of "Genuine" or "LIFE LONG" applies to this, no one yet knows. It is certainly not illegal.

Thanks a lot, for your answer. so once Microsoft release Official Win 10 then I have to install again by formatting PC, then Activate windows 10 by legal purchase key.

because all old Beta versions will not having that all functionalities, compaire to latest officel release version of wondows 10 may be.

thanks

Or if you have a genuine Windows 7 you could also Upgrade to Windows 10
