create a lan network windows 10

I'm using windows from version 98 and have started sharing files and playing through Local Networks with Windows XP, from there it becomes more difficult to design a LAN with each new version of Windows, yes . It's as if Microsoft is taking away their users. from this feature and now with the latest version of Windows 10 they have succeeded, it is impossible to make any kind of network local (perhaps for a printer), before I do the random steps to make it work:

create a lan network windows 10

Changing IP addresses

Generates a password for each user

Restarting millions of times the computers

Allows access to all types of networks (public and private)

Sharing primary hard drives

...

and secretly it works, with windows 10 it's another tricky story, sometimes only the first PC appears on the second PC, sometimes the other way around, sometimes they don't show up at all and the most mythical mistake is when I try to connect with the other. PC and I receive a message telling me that I can incorrectly identify identifiers, such as forgetting a password I use frequently or not being able to copy the username.

 

See, I beg you, I only need 2 things, information on why Microsoft is making such a thing so difficult and is there a basic way to create a proper Local Network at least to play with my brother of some games.
