What a concentrated conclusion. To whom it might concern, those activate methods were tested by many experienced users and it's safe for activation

@fxsantu: I got your point. The script's author found a hole in the MS activate system and make it legal somehow.
In fact, I tried to activate my LTSC Windows with that script. After that, I formated my partition and made a clean install LTSC Windows. It re-activated again when my PC connected to the Internet. I have thought everything's OK and do no more digging until I read your opinion.
Are there any clues that I have a misunderstanding and does it safely for activation in your personal view?
Thanks in advance.
