VAC Disconnect Error (not ban) on freshly installed Windows

[Zombie]

Hi, I know that this has been a problem throughout many years. Some processes and programs conflict with VAC so it happens. I've seen it dozens of times and some time ago I had a same problem caused by CCleaner. However this time I'm on a freshly installed Windows 10, nothing installed except for Steam, CSGO and Skype. I've posted on reddit and got some decent replies on what to do there, I've also contacted valve, hopefully I'll get some sort of explaination.

So I'm able to play for like 15-20 minutes and then I get randomly disconnected. I can rejoin but I don't want to be disconnected in the first place. It costed me a 30 minutes competitive cooldown this morning. I can copy/paste my reddit post with more information or I'll be happy to discuss it over here.

If anyone had similar problems on freshly installed Windows, please let me know how you fixed it.

EDIT: I've tried all of the FAQ solutions that Valve/Steam provides, nothing seems to work.

Thanks in advance.

Is Windows 10 fully updated?

Is CSGO and/or Steam installed under %programfiles% or %programfiles(x86)% environment paths?

What feedback is displayed when applying the Data Execution prevention settings?

Have you or system administrator enabled Core isolation settings?

Have you or system administratorenabled Secure UEFI boot settings?

Have you or system administrator enabled Controlled Folder Access settings?

Have you or system administrator enabled Exploit protection settings?


____


"Steam, CSGO and Skype."

Typically, in my experience, most times people make these claims, it turns out they are mistaken.

Please post a complete list of installed software (via appwz.cpl) and running services (services.msc)

Hello, thanks for the reply.

Yes, w10 is fully updated. It's located under %programfiles(x86)% path.

Googling out my answer I've also enabled DEP for all as well.

No idea about Core isolation, Secure UEFI boot, Controlled Folder Access and Exploit protection settings. I haven't found anything in my searches for the fix about that but I'll surely follow the procedure if you have something in mind.

Here's a appwiz screenshot: https://imgur.com/a/Z0SCoAp

As you can see, I've installed nothing besides what I mentioned. I've also exported .txt file of the services as I think it would take 5 screenshots to SS all of them but as I said i really haven't installed anything besides the stuff that comes along with Windows. I have disabled Powershell. And in regards to services I've disabled all of the XBOX stuff.

Please check your system settings and post back with the response.

I'not viewed your screenshot since I do not access insecure websites.
" the stuff that comes along with Windows."
Depending on where & how you purchased the system and/or the OS, there can be nbundled software and other rd party content included.

There may also be certain policy settings that are enforced which are preserved even through repair and reinstallation of the OS - particularly when cloud storage is permitted.

That's just a screenshot of my installed apps uploaded to imgur lol, one of the most popular pic uploading sites but that aside, as I've already said. I've gone from the top to the bottom of the FAQ "Disconnected by VAC" page and you're pasting me a part of their solution. I wouldn't be posting here or on reddit or anywhere for that matter if any of that worked. So regarding boot, I'm getting the default message I should be getting: "The value is protected by Secure Boot policy and cannot be modified or deleted."

Regarding my Windows, I downloaded ISO from the Microsoft website since I already have a key and I've made a bootable USB, formatted SSD and did a clean install so I haven't got clue what do you mean with bundled software. Only the Microsoft stuff is here, nothing 3rd party.

Open CMD as an administrator, and type in "ipconfig /flushdns" and press enter.
After that type in "ipconfig /renew" and press enter.
Now type in again "ipconfig /flushdns" and press enter.
Try deactivating your firewall and start to play on a server.

Tell me if it worked or not.

Did that as well, problem is while testing last day I manage to play couple of full deathmatch games. 30+ mins of gameplay, nothing happens. I finally think its resolved and then I queue to workshop, just to change crosshair and guess what, it happens again, just out of the random. That's why I don't wanna queue MM games until I know that I won't be disconnected. With that said, it's a bit hard to test, because sometimes as I mentioned it disconnects me at the start, sometimes in the middle, sometimes doesn't at all (deathmatch games).

This may also indicate a Steam Service failure. Please try repairing the Steam Service:
Exit Steam.
Click Start > Run (Windows Key + R)
Type the following command:

"C:\Program Files (x86)\Steam\bin\SteamService.exe" /repair

(If you have installed Steam to another path, please replace C:\Program Files (x86)\Steam with the correct path.)

oh guys i really appreciate, but that's just copy/pasting the FAQ page, and as I've said I've gone through all of it and if something had worked I wouldn't have posted here. Thanks anyways, I hope Valve replies soon confirming I can continue playing without being randomly disconnected at any point.

3 times now I am asking you to divulge the feedback message from when you enter these commands.

If you don't wish to cooperate, that's fine, your prerogative - but then don't expect the issues to be resolved.

Have you read entire comment or what? I posted feedback I'm getting while executing boot fix. I've literally quoted what it says since you don't open screenshots. Never mind, apparently it's a thing on fresh windows installations and has been working since I posted. Thanks anyway.

So does it work now?

Worked when I came from work last night. Played 2 casuals just in case but I'll test competitive tonight.

[NULLYUKI]

Awesome! :D
Maybe it was just a bug or anything.
