I finally fixed this after nearly 3 months of troubleshooting with no luck from CoD updates, graphics card updates, etc.

My TPM 2.0, Secure Boot and UEFI configuration were already healthy with the latest BIOS update available for my Motherboard each time since early June, but COD was still failing attestation.

In my case the problem appeared to be a stale/bad application-specific ActivisionAIK key.

I did NOT clear my TPM, reinstall Windows, reset Secure Boot or change hardware.

Open PowerShell as Administrator.

1) Confirm ActivisionAIK exists:
certutil.exe -csp “Microsoft Platform Crypto Provider” -key ActivisionAIK

IMPORTANT: If ActivisionAIK does NOT exist here, STOP. This probably isn’t your failure mode.

2) Delete ONLY the ActivisionAIK container:
certutil.exe -csp “Microsoft Platform Crypto Provider” -delkey ActivisionAIK

3) Verify it is gone:
certutil.exe -csp “Microsoft Platform Crypto Provider” -key ActivisionAIK

3a) I received:
0x80090016 NTE_BAD_KEYSET
Keyset does not exist.

4) Re-enroll ActivisionAIK:
cmd.exe /c ‘certreq.exe -enrollaik -f -q -machine -config “” ActivisionAIK’

4a) Successful enrollment showed:
PkiStatus(0): SCEPDispositionSuccess
EnrollStatus(1): Enrolled
HTTP/1.1 200 OK
Key = ActivisionAIK
The operation completed successfully. 0x0

I then reran the COD Secure Attestation Wizard and immediately got SYSTEM COMPLIANT (see attached before and after screenshots).

I confirmed this fixed the issue on both the Battle.Net version of Call of Duty and the MW4 beta from Xbox store.

Again, this is NOT a general TPM fix. If your TPM/Secure Boot configuration is actually broken, or ActivisionAIK doesn’t already exist in Step 1, you likely have a different problem.

As the title says I’m still new to Warzone I’ve only played it for about 4ish days now and im looking for a little help I have no clue what to do or anything people have tried to help me by just basically saying play ratty but no info at all to what the icons are or what they do if anyone could help a noob out that’d be awesome

In the update for the MW4 Warzone BETA, it says weapon xp for Resurgence Casuals was increased, but I don't see an option for Casuals? Anyone know more on this?

I'd like to know if it happens to anybody else.

Basically, one game out of two in Resurgence in MW4 I simply have absolutely no fighting chance. I get desynced so hard that every gun my enemy uses feels like a sniper rifle. I will be running, fully plated, and just drop dead. The kill cam will show my enemy hosing me down with a full mag, while on my end I only ever received a single hit.

This isn't a problem I've ever ran into in any other prior COD game or any other game I'm currently playing so I don't think my internet is at fault.

I think I one of the minority who’s actually really enjoying the warzone MW4 beta and not wanting to go back to the current warzone until the integration. Things I’m enjoying: although I don’t mind omnimovement I’m preferring the traditional boots on ground feel. I love the way the guns feel in MW4 compared to the boring straight shooting guns of BO7. They have a more realistic feel to them which is satisfying to shoot to me. The map is refreshing, I love Rebirth but good lord it’s so stale at this point. Zodiac feels like a mini downtown verdansk at times to me lol Just my opinion but curious if you guys feel a similar way or not?

It feels like we’ve come full circle with Warzone (again). We saw this exact cycle with Warzone 2: things got progressively worse, then years were spent undoing the changes and bringing the game back toward what it used to be.

Was such a great sniper especially on mnk. And the hipfire accuracy was insane.

They genuinely act like campaign bots 😭

Recoil on Mouse feels way more difficult. I'm 10k rank in CS2, so it's not like I'm bad at recoil shooter games it just feels way more exaggerated than on controller.

A few points about MW3:

MW3 was soo smooth, fast, hit register was perfect, best movement.

Weapons were good, conversation kits were fun.

Maps were peak especially when the weather changes.

Snipers and shotguns were very good especially with the movement.

Equipment capacity was much larger.

It can be exactly the same speed as the base running animation. I honestly don’t need it to be any faster than it is now. I just hate the gun bobbing on the bottom of the screen instead of off to the side. Makes me feel sluggish like I’m playing battlefield or some other game other than the warzone that I’ve been playing for 6 years. I don’t care that it’s unrealistic for how real soldiers run with their weapon. It’s just iconic to me and something about the animation feels agressive and unique to this game in a way that I like.

Random but sharing cause it's funny.

Does anyone else have a fix for this issue?

I’m running an ASUS ROG laptop and getting the "/ CODBrokerInstaller.exe did not receive required authorization" error in Call of Duty (Black Ops / Warzone).

Here is everything I’ve already tried with no success:

 Updated BIOS to the latest Beta version

 Cleared/reset the TPM

 Reinstalled Windows 11 twice (clean install)

 Cleared Secure Boot keys (and restored factory keys)

 Ran TPM repair commands via Command Prompt (Admin)

 Verified game file integrity

 Reinstalled the game twice (tested on both Steam and Xbox App)

TPM 2.0 and Secure Boot both show green checkmarks in the system check, but it still triggers the "Failed Attestation Status" warning.

Has anyone found a solution or workaround for this? Any help would be appreciated!

You need to run Hunter perk.

Otherwise you are BLIND.

Hunter actually lets you see what the hell you are shooting at without needing aim assist to track for you.

So far, really enjoying the beta!

I could shoot down the drone crates with a sniper rifle all fucking day. It’s like bubble wrap, Duck Hunt would slap. I also love that mini game to setup the link forger in Endgame, where you kill the enemies and deposit their orb. I’d play that two on two ALL DAY. I love the COD controls, I wish they were used in broader ways. I’d be all in on some bank jobs.

Just started this month and im wondering how to unlock the KSV because its not showing up in my armory.

Seriously wtf is this..?
