FACEIT AC: "missing important security updates" | Was working 1.5 weeks ago | Cannot install manually (DISM Error 2)

[vaddos412]

Hello everyone!

I'm currently using Atlas OS on Windows 10 22H2 and I'm trying to launch the FACEIT Anti-Cheat. However, it blocks me with the following error:
"Your system is missing important windows security updates."

Important context: Just about a week and a half ago, the anti-cheat worked perfectly fine, and I was playing FACEIT on this exact setup without any issues. It seems FACEIT recently updated their minimum required security patch baseline.

Since the Windows Update components are stripped/disabled in my build, I tried to install the latest updates manually to satisfy the AC. Here is what I did:

Downloaded the latest Cumulative Update for Win 10 22H2 .msu from the Microsoft Update Catalog.
Extracted the .msu file and tried to install the .cab file via CMD as Administrator using:
DISM.exe /Online /Add-Package /PackagePath:"C:\CAB"
The issue:
The Servicing Stack installs successfully (100%), but the main update payload (Multiple_Packages) fails at about 5% with Error: 2 (The system cannot find the file specified).
I assume DISM is trying to patch components that were physically removed from the WinSxS folder by Atlas OS.

I also searched the internet and saw old mentions of a community tool called "HoneCtrl" that supposedly forced specific FACEIT KBs, but that project seems to be dead/discontinued now.

My questions:

Since it worked just a week ago, is there any specific small KB package or a modern script
to bypass this new FACEIT check on a heavily stripped Atlas build?
Or is my only option to completely reinstall Windows and re-run AME Wizard without disabling security updates?
Thanks in advance for any help!

Hey !

I can't answer or solve the problem all by myself, but just by looking at I'm currently using Atlas OS on Windows 10 22H2, maybe it's also because of that ? I think the best thing to do is to switch to Win 11 and enable basic security checks ?

And for the questions, a modern script to bypass this new FACEIT check : don't do that. That's the best way to get yourself ban, it's to bypass the little things to continue playing, you'll probably get flagged by the anti-cheat and banned tbh.

Cheers,
Neven :)

I do not recommend staying on Windows 10, as some features may be broken.

Since Microsoft and some app and game devs do not have their focus on Windows 10 anymore, this is not a platform you want to say on.
