Windows 10: Risk of system getting hacked through the internet or Wi-fi?

Dear everyone

I am not a high profile person or anything like that. I just dislike the idea, that someone with bad intentions could access my personal files, documents, photos etc. (personal diary, baby pictures of my children etc.)
I am not worried about anyone getting a look at my internet traffic / man-in-the-middle attack etc. I am only concerned about, that someone with bad intentions being able to access my personal files.
I assume, that it is not impossible to hack my system and get access to my files, but how hard would it be for someone commited to the task?
Is the only way to access my files, if they planted malware on my system?
Or if they accessed screen share?

My questions concerns both:
If the person accessed / hacked my wi-fi / home network
Or
Only through the internet


Settings:
Microsoft Windows 10 Home
Windows login password protected
Windows Defender firewall
No file or folder sharing enabled
Network discovery is turned off
File and printer sharing is turned off
AVG registers threats in real-time
All software drivers etc. fully updated

Wi-fi is password protected
Network / Wi-fi profile: Private
Router security WPA2-Personal

I become uneasy, when I read posts like this, which makes it sound easy:
Aaron Shbeeb's answer to Can a hacker control my computer through Wi-Fi connection only? - Quora
Hargarbage Dangwal's answer to How do I hack a computer on same network? - Quora

Please let me know, if I shall add more info concerning the above.

Thanks in advance for replying

Best regards

:)

 

Trouble Changing Wi-Fi Password


I've been following the following steps to change my Wi-Fi password for some time:

1. Launch Control Panel.
2. Click "Network and Internet."
3. Click "Network and Sharing Center."
4. Click "Wi-Fi...."
5. Click "Wireless Properties."
6. Click the Security tab.
7. Check "Show characters."
8. Enter the password in "Network security key."

Those steps have been working just fine, but today I discovered a new wrinkle. If I change the password inside the router first, "Wi-Fi..." doesn't appear in step 4. This isn't much of a problem at home, because I can just change the password in Control Panel before I change it inside the router, but it would be a problem at a public hotspot, or something of that nature. I also tested Brink's instructions in "How to Connect To a Wireless Network in Windows 10," but they don't work for me either. How can I fix this?

wi fi connection

After windows 1903 update I don't have any wi fi connection or icon showing and have tried many suggestions on how to get it, but none have worked.

Can you provide a step by step instruction on how to get wi fi icon and network.
