Win 10 ISO_Fresh Install_How to activate it ?

Did you do the required update of an activated Windows 7 or Windows 8 install before the clean install?

 

Won't work, the first time you have to update an installed system to get activated. After that you can clean install and activate.

 

did i need to add any serial on clean install (After already Upgraded and Installed,Activated) or i need to use Advanced Token Manager ...

or can someone explain complete procedure

Win7 Pro upgraded to Win10 Pro and activated too
- and now i want to do clean install with Win10 Pro in same machine

 

and now you can and it will activate

 

but questions was

did i need to add serial / which one
did i need to connect in internet to activate / or no
did i need just to restore backup with Advanced Token Manager ..
or just install (no key and it was activated by default ??).

 

Once you are already on Windows 10 after a successful upgrade from either Win 7 SP1 or WIn 8.1, and you're activated, you can do a clean install.
No need to add serial/key, in fact when it asks always hit skip, do not enter anything.
Yes you need to be online after installation so that the servers can re-activate you.
No need to restore backup
And finally, yes, just install, no key, it will be activated by itself.

edit: regarding activation, the servers once you installed windows 10 coming from an eligible OS (Win 7 with SP1 or Win 8.1) will use your hardware to uniquely identify you, so no more need for keys or anything like that. Once you are activated, you can do a fresh/clean install on that machine as many times as you want, never having to enter a key, and as soon as you are online ans the servers see your hardware again they will activate you automatically (just give it some time or tries because so many people are doing it it can take a little time, but worry not, you will be activated again).

 

Clean install means installing from a bootable USB or DVD right?

 

Correct.

 

That means you format the drive

 

I also heard that refreshing in Windows 10 is also same as Clean install. Is this true?

 

Yep, afaik this is true .

 

Did a clean install of pro and used one of the emulated kms to activate. Works fine. But if the kms protocol changes then I'd probably be out of luck.

 

I want to clear up that

Windows 7 activated and then upgrade to Windows 10 activated works fine.

But after that, if you FORMAT your hard drive and install Windows 10 (with what serial I might add) you Windows 10 will probably NOT activate. It makes no sense. The only way that could happen is that when you do W7 -> W10 upgrade is that Microsoft stores some kind of information of your PC (could be your MAC address) on its activation servers and then when you format and clean install Windows 10, it activates based off that. This is simply a "glitch" because of OEM activations and being unable to blacklist OEM keys but make no mistake: One year later, this will NOT work.

Another method needs to be found that allows a brand new system with a brand new formatted hard drive/SSD that Windows 10 can be installed clean and then activated clean. No upgrade method what so ever.

 

Buddy, that route actually exists. As it did for all predecessors.

If ya want it hasslefree: BUY A LICENSE!!!! Then you can do as you like.

No need to use the Free Offer at all.

 

Phone activation doesn't work, so unless they come up with a way to de-activate and re-activate on different hardware, I predict a lot of people migrating to kms activation in a year.
