How to legally upgrade licensed Windows 10 Home Single Language to Pro for free?

Question

Windows

The laptop originally came with Windows 8 Home Single Language installed and was legally and officially transferred to Windows 10 Home Single Language. Are there any ways to upgrade Win10 to Pro for free in this case, and if so, which ones?

Answer 1

Perhaps if you get a job at Microsoft, you will be able to upgrade from Home to Pro for free and legally.
If you decide to use this option, then be thoughtful in choosing a position, I would advise you to take a leadership and as high-ranking position as possible.
Good luck.

Answer 2

Buy from the store and upgrade.

Answer 3

The main way to get a free license for products from Microsoft is to join those who participate in their programs.
The simplest one is if you are a student and your university is connected to the Microsoft Academic Alliance or an equivalent program, when for a simple subscription fee, a university division (not all) receives licenses for almost the entire product line, and most importantly, allows students and teachers to take these licenses home.
There are a lot of nuances, for example, if you make money with their help, then you are violating the license, but to be honest, there are so many pitfalls in licenses from Microsoft that they go through the forest.
ps I remember exactly there was a license, for start-up entrepreneurs, for 3 or 5 years full access is given almost for free to a bunch of products, including operating systems (with the ability to make a profit), where employees can also get a license for free.
