The following is the case: my laptop which had already been preinstalled at purchase Windows 10 goes to my mother. But since she does not handle Windows 10, she wants Windows7. Now ask me 2 questions:
1. Do I have to buy Windows 7 again and if so where and what is the most reliable source where I can get a real key one hundred percent?
2. Or I can simply download Windows 7 from the Microsoft side to a bootable USB stick and then reinstall on this laptop where Windows 10 is already on it and finally in the 30-day period Windows 7 with the Windows key of Activate laptops (which is on the bottom of the laptop top)?
Where best
Maybe it's downgrade but look here

Otherwise on Ebay for ~ 5 euro

See "This says downgrade your windows license"
This is possible with the Pro versions of Windows 10, unfortunately not with the Home version. Alternatively, a key costs only 5 EUR.
If the key is for Windows 10, then of course you have to buy the one for Windows 7. Look, for example At softwarebilliger.de
But since she does not handle Windows 10, she wants Windows7.
Why does she not realize that? So big are the differences in the operation, yes not now. But Windows 7 will also soon go the way of Win XP and no longer be supported. Therefore, such a change actually makes no sense.
As it reads, under certain circumstances a downgrade seems to be possible. I would not do it anyway.
