What ? So Windows 10 isn't free ?
No, it is not.
You get a 'free' Upgrade, if you have already given Microsoft money by purchasing Windows 7 or 8.
If you have not, then you must purchase Windows 10.
but i had genuine windows 7 so from windows 7 i went to windows 10 insider preview. So it doesn't work like that right
This depends on how you installed Windows 10.
I'm thinking you just did a clean install of the Tech Preview.
So...to fix this (and you're not gonna like the answer)...
Install your old Windows 7. Activate, and go through all the updates.
Then Upgrade to Win 10.
This, of course, blows away all your existing installations, etc.
Or buy Win 10 and activate your existing install.
