Windows 10: Activating Windows with KMS tools

Hi there! There are a lot of KMS programms that activate Windows OS and Microsoft Office. If anybody knows about KMS tools, can you tell me how it works, what actually KMS tools and is it legal or not?

Also I wanna ask about free Windows activation keys. What if I activate my Windows OS with that free activation keys on the internet? Is it legal?

I'd be happy if you give me a full answer. Thanks

:)

 

Windows 7 activation with KMS

KMS Activation threshold

I am looking into setting up a KMS server vs using a MAK for a small (<100 clients) offline network of PCs with Win10 and Office 2016. I did a lot of web searching (Bing, obviously) but still have a few questions that I was not able to find answers to that
I was hoping someone could help with.

1. I know KMS has the 25 PC threshold before it will activate any, but what happens on the 26th activation request? Will the KMS server activate the 26th PC or does the threshold count start over and it will wait for 24 more activation requests?
2. After a re-image, I read that we can use the same MAK to activate Windows 10 using VAMT if we saved the .cilx file as long as there haven’t been any major hardware changes. Is this possible for Office 2016 as well? I haven’t been able to find any
   documentation on it.

Thank you!
