Windows 10 requires activation after installation, what should I do?

Question

Windows

I decided to update windows7 sp1 to 10 on my sister's laptop, complained that it was buggy (it's been windows since 2009), so I decided to experiment a little with 10, I've been using it since the official release. Everything went well. But after all, it turned out that some functions were cut down. Particularly personalization. When you enter the settings, it is written in red on top that in order to personalize your computer, you need to activate windows. The fact is that 7 was broken, but activated. During the system update everything was o'key. How to deal with this "hello from Gates"? Offers to either contact the support service (which would not be desirable, broken all the same), or buy in a virtual store, and the price tag bites.
Well, I bring to your attention a screenshot:

Folder "GodMode"

Answer 1

Save valuable files and install a cured OS, or use miracle programs to "activate"

Answer 2

In fact, you can activate the top ten in a bunch of ways: from buying a key for a penny (for example, on aliexpress), you can also search for free ones on the Internet. Or, as already mentioned above, with the help of miracle activator programs. I am an adherent of the second option, I often use this activator , there were no problems.
