Press Windows + R
Type --> control panel and OK.

Network and Sharing Center
Change adapter settings
If it's present, delete it

Also check in network settings

Hi Kaneagle,

with the diagnostic scan, we'll see if there are any "remnants" of the VPN, even though we don't know which one it is

See you later

There is nothing in remote access and VPN options?

Here is the message displayed by the troubleshooting utility.

Perform a system restore and choose a date before the VPN installation.

Windows + R
Type --> rstrui.exe and OK.

Check in the Windows Defender firewall.

Hello

to check if there are any traces of the VPN left, do this and post the reports

download FRST from (Fabar) to your desktop (the one on the PC with which you will download it)

once done, transfer it to a USB stick that you will plug into the PC that needs it, and run it

do the same with the FRST reports, transfer them to the USB stick to post from the functioning PC in your response

PS: since you don’t have a connection on your PC, download FRST from another PC making sure to choose the correct architecture (32 or 64 bits) for the one you will use

PS: take the one that corresponds to your PC (32 or 64 bits)

https://www.commentcamarche.net/informatique/windows/169-32-bits-ou-64-bits-comment-savoir/

run it as an administrator (right-click)

at the end of the scan, the FRST and ADDITION reports will appear on your desktop and in C:\FRST\LOG

post the reports via cjoint

if you have any questions...

PS: hi Kaneagle and MPMP10

Good evening,

Has he tried to see if he has a connection in safe mode?
He might still have some VPN services running despite the uninstallation.
I had the same issue with Comodo software back when I had Windows.

"With the diagnostic scan, we will see if there are any "leftovers" from the VPN, even though we don’t know which one it is."

If it's mentioned in his first post. PIA - Private Internet Access, a paid VPN that is quite reliable and well-known.

Hey Balro

I'm going to bed, me dumb, tonight, because I thought "private internet access" meant "VPN"

Anyway, with the FRST scan, we'll see if there's any leftovers

Hello,

@billmaxime,
Not less dumb but smarter :)
But it’s true that the name can be a bit misleading.

@brupala,
When I talk about the seriousness of the VPN, I’m not referring to the technical side but to the seriousness of the company.
It’s not one of those free VPNs that are popping up everywhere and whose origins can sometimes be questionable.
As for the IPV6 issue, I read that it’s better to disable it to improve your anonymity.

Have a good day.

"How do you measure the seriousness of the company?"

That's already a start, right?

After that, you can very well use a VPN that is not part of the Five Eyes, but that doesn't guarantee anything in absolute terms.
In that case, you shouldn't install anything, even software that seems harmless and has nothing to do with a VPN, but that requires a discipline that I personally don't adhere to.
As with any product we use, what matters is the level of trust you have in that product; it all remains subjective, but that's how it is.
Is it better for a French ISP to have your browsing information or a VPN in the middle of nowhere? Honestly, I don't have an answer; I just know that 100% anonymity on the internet is a pipe dream.
