I can't change my network identity in the system.

Hello, I'm not very tech-savvy. So if there are any inconsistencies in what I'm trying to make you understand, that's normal, so here's my issue:

It's been a year since my PC was repaired by an individual (under the table, of course). He formatted the PC and reinstalled Windows 7 Professional on my machine.

When I go to Control Panel, System, Remote settings,
Remote Assistance: in this tab,
the box "Allow Remote Assistance connections to this computer" is checked (enabled)
Is there a risk? In other words, can the person who repaired my PC and reactivated Windows access my files, or is that not the case?

I'm asking this because when I click on "What happens when I enable remote assistance," risks such as worms, access to my files, and the intrusion of malware are mentioned.

Furthermore, still in "system properties," but this time in the "Computer Name" and "Network Identity..." tab, I click and it shows: "select the option that describes your network" and it's checked the option "This computer is part of a business network. I use it to connect to other computers in the company"

So I check the other option "This computer is for private use. It does not belong to a business network" and I hit next, and it tells me to restart to apply changes. So I restart and go back to this program, and I see that nothing has changed (it still checks that the computer belongs to a business network).

Another issue, the guy set up an administrator account and not a standard account
(control panel-user accounts-select the new account type). Here again, the same problem as before: I can't choose a "standard user" account because it's disabled, just like the "change account type" box
by the way, Windows recommends the standard user account, not administrator.

On top of that, my keyboard is set to French, but often it produces different characters than the ones I'm typing. Although my antivirus Avast is in protected mode and shows no error messages or problems.

So here's a little recap given all these elements:

Can the guy access my data (files, photos, videos, etc.) on my desktop, on my C & D drives in "COMPUTER" because I care about that and it's personal!
AND can he basically do things remotely from his place that affect my PC? If he has access to my data, should I be informed by a warning message, or can he do it without me knowing?

Or am I just being paranoid? ;)

Thank you for your clarifications on this topic...

P.S.: This guy works under the table, and when there's a problem, he takes the PC without trying to fix it on the spot.

Hello,
no, for him to connect remotely to your computer, he needs your session password.
And even if he managed to do it, you could disconnect him at any time!
Besides, even before he connects, an alert message would ask you if you accept a new incoming connection!
Are you reassured?

but I believe he has my session password. Moreover, he sold me another laptop (still the same issue) that he himself built and configured from A to Z (Windows 7 installation with product ID 00371-OEM-899 ... etc. in short, he configured everything).

And as I already told you, he checked the option "allow remote assistance connections to this computer" in system-"remote usage settings"

And when I go to "select users," it shows me that "users as well as members of the administrators group can connect to my computer even if they do not appear here"

All this is a foreign language to me

Furthermore, the system protections for my C & D drives were disabled in "system protection"-"protection settings"

My questions :) :

Does the guy who installed Windows and sold the PC belong to one of these users or members of the administrators group? Is it certain that he has no access to my personal files (photos, etc.)?
Is it normal that my PC is not intended for private use?
And is it therefore normal according to you that
"my computer belongs to a corporate network and that I use it to connect to other company computers"?
And that I cannot change this usage to make it personal (which I wish)?

Anyway, thank you for your clear explanations ;)

NB: Furthermore, he lives close to my place (is there a connection with the network?).

Hello,

No, if you are using a LAN (local network) that is secured with a password (WPA2-PSK), it has no link to your network.

Rest assured, your firewall protects you from unauthorized incoming connections from other computers.
It's normal for your network to be configured as a small business network since you are on the professional version of Windows.
However, your files on your C and D drives are available if:
Someone connects to your LAN.
Or if you share them as shared drives.
Any other questions?

Ok, my other questions then :)

Question 1) So how do I know if I’m using a LAN (is it inherent to every PC and network)?


2) And the shared drive: is it a common network related to the HomeGroup?


3-a) Where does the LAN password come from? 3-b) And is it this password that enables remote assistance? Is it protected?

If I understand correctly: when someone tries to connect to my LAN, my PC notifies me?
And asks for my permission?



When I go to Run (“search”) I type “firewall” and I get a window “Windows Firewall with Advanced Security on Local Computer”. This window indicates for each of the 3 different profiles (domain profile, public profile, and the public profile is active) that Windows Firewall is enabled.

On the other hand, when I open “Avast user interface”, Avast (the window that opens) indicates “Secure, Up to date, All agents active” but in the firewall icon it states “(firewall) unavailable for free” but also “Add a firewall to prevent intrusion attempts and hackers from stealing your data”

4) So what takes precedence? Is this already activated firewall reliable (does it protect, is it sufficient) or is it necessary to add the antivirus firewall by taking a paid version?

N.B.: Because the antivirus version I am currently using and have always used is free (trial version) which I renew every year. This version indicates that it protects my system but not against spams, hackers, malware, etc.



5) Still in the same window, all the way to the left there are settings “Inbound Traffic Rules”, “Outbound Traffic Rules”, “Connection Security Rules”, and “Analysis”


And when I click on “Inbound Traffic Rules” and “Outbound Traffic Rules” there is a whole list of names like “Network Discovery”, “Basic Network Management”, “Basic Network”

Some are enabled (most of the basic networks whether they are inbound or outbound traffic).
What are these basic networks? Are they interconnected? And what’s the difference between an inbound basic network and an outbound basic network?

In the “Analysis” tab - “Firewall” another list appears. With several basic networks such as “Neighbor Discovery Publication/Solicitation”, “Multicast Listener Done”, etc.
Do you know what this means?

Do I need to (re)set these indicators?


6) This time in the Analysis for the 3 profiles (domain, private, public is active)
I’m told that “incoming connections that don’t match a rule are blocked”
and that “outgoing connections that don’t match a rule are blocked”

Should these settings be left as they are or changed for better security?

-A LAN (Local Area Network) is a local network made up of several computers that all have access to the same internet resource and can exchange data through shared folders (or drives).

- Yes, but it's not a network, it's a resource ;)
