Windows 11’s optional KB5124010 update has started causing crashes in several popular online games. Reports are piling up from Battlefield 6 and Wardogs players, with launches failing or games closing within minutes. Why do games crash after KB5124010? How can you get back to a stable setup?

Which Games Are Crashing After KB5124010?

Battlefield 6 and Wardogs make up most of the complaints so far, and some Battlefield 2042 players report the same thing. Players say games either refuse to launch or drop to the desktop within a few minutes of starting. Screen blackouts, freezes on the anti-cheat screen, error codes, and silent exits are the most common symptoms.

These games all use EA Javelin Anti-Cheat, which points to a clash between the update and the anti-cheat layer instead of the games themselves. That is an inference drawn from player reports and not a confirmed diagnosis. The update is listed as the 2026-09 Preview Update, and it moves PCs to build 26200.9550 on version 25H2 or 26100.9550 on 24H2.

How Do You Uninstall KB5124010?

Follow the steps below to remove KB5124010 from Windows 11.

1. Press Windows + I to open Settings.
2. Select Windows Update from the left menu.
3. Open Update history.
4. Scroll down and choose Uninstall updates.
5. Find KB5124010 in the list and click Uninstall.
6. Restart your PC once the removal finishes and launch the game again.

Several players report that games ran normally again after removing the update. That fix has not been confirmed to work for everyone, though. Competitive players may want to be careful with optional updates until a proper patch arrives.

Has Microsoft Responded to the Crashes?

There is no sign of an official Microsoft statement on the problem yet. A representative from the Wardogs team did confirm the game crashes with a WD-L020 error code. According to that representative, there is no quick remedy right now, and uninstalling the update is the only temporary workaround. EA acknowledged a similar Insider build clash with Javelin earlier, but no EA statement about this update has been reported.

Should You Install the KB5124010 Preview Update?

KB5124010 is an optional update, so it does not install unless you choose it. If the option to get the latest updates as soon as they are available is turned on, though, it can download in the background. It is roughly 1.5 GB through Windows Update and about 5 GB as an offline installer. Everything in it is already scheduled to reach all PCs with the October 13 Patch Tuesday release, so skipping it now costs you nothing, and keeping that option off on a gaming PC is the safer move until the crashes are sorted out.

The crashes after KB5124010 show how fragile the link between Windows updates and anti-cheat systems can be. The exact cause is still unconfirmed, but removing the update is the most reported temporary fix for now. Holding off on optional updates on a gaming PC looks like the safer choice until a fix lands. If you are hitting these crashes, tell us which game and error code you see in the comments.

Frequently Asked Questions

What do you lose by uninstalling KB5124010?

You lose the improvements it brings, including Bluetooth changes, File Explorer tweaks, and Copilot key remapping. All of those are set to arrive anyway with the October 13 Patch Tuesday update. Removing the update is not a permanent loss.

Are games other than Battlefield 6 affected too?

Yes, Wardogs players report the same crashes, and some Battlefield 2042 players describe similar problems. The common thread is EA Javelin Anti-Cheat. Reports do not describe widespread trouble in games that skip Javelin.

Will Microsoft release a fix for the crashes?

Microsoft has not issued an official statement yet, so there is no timeline for a fix. The company did acknowledge a similar game-crashing update issue last month. A confirmation for this one may follow the same path.
