Sharing my Windows 7 activation experiences

Sharing my Windows 7 activation experiences:
Why Windows 7? Since it comed with my buyed laptop!

You need an original DVD with a boot-able kit of Windows 7!
My version was Windows 7 SP1 x64 (64 bits).
You need an internet connection in order to activate you Windows 7 license,
first time it didn't succeed, second time the Windows was genuine!
A Windows Home Premium license will not work with a Professional version of Windows.
But for Home Premium you can use a 64 bits version of Windows or 32 bits version of Windows.
The key looked like this:
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX   XXX-XXXXX-S07IT
The key was written on laptop back was in full format without space (" ")
the actual key used to activate Windows 7 was only first bolded chars!!!
I still don't know why only first 5*5 = 25 chars!!!

That's not necessary. You can create custom bootable DVD as well. For example, see https://www.raymond.cc/blog/create-x86-x64-all-one-windows-7-iso/

Because Windows key is always 25 chars. The rest is a laptop model. Quick Google search tells me you most likely have some kind of Samsung with i7 processor.   NP-RC530-S07IT? NP-RC730-S07IT?

Actually the last part "-S07IT" is from MODEL CODE of laptop and has nothing to do with Windows activation key:
it was a typing error! "-S07IT" is not part of Windows serial!

The left XXX-XXXXX which is not part of actual Windows activation key seems to be the Windows version:
