Microsoft has released an emergency Windows 11 24H2 update to address an incompatibility issue triggering restarts with blue screen of death (BSOD) errors on systems with Easy Anti-Cheat.

The out-of-band update (KB5063060) is a revised version of the Windows 11 KB5060842 cumulative update released during this month’s Patch Tuesday after many customers reported experiencing system reboots and IRQL_NOT_LESS_OR_EQUAL BSODs tied to ntoskrnl.exe or EasyAntiCheat_EOS.exe crashing on computers running various games, including Fortnite.

Microsoft said on Tuesday that the emergency update addressed a compatibility issue and rolled out to “a limited set of these devices” running Windows 11, version 24H2.

However, the company didn’t initially share what hardware or software configurations were affected and what impact KB5060842 had after being installed on incompatible PCs.

One day later, Redmond revealed that the issues only impacted devices running Easy Anti-Cheat, a massively popular anti-cheating service installed with hundreds of multiplayer games (including Apex Legends, War Thunder, Dead by Daylight, ELDEN RING, Rust, Squad, NBA 2K25, and many others) to prevent cheating while playing online.

“This update addresses an incompatibility issue where Windows might restart unexpectedly when opening games that use the Easy Anti-Cheat service,” Microsoft said.

“This update downloads and installs automatically from Windows Update and Microsoft Update on devices with Easy Anti-Cheat installed and on devices that have not installed KB506842 yet,” it added.

If you can’t install the KB5063060 out-of-band cumulative update via Windows Update, you can install it manually on x64 and arm64 systems after downloading it from the Microsoft Update Catalog.

Microsoft also placed a compatibility hold in October to block Windows 24H2 upgrades on Intel Alder Lake+ and vPro systems because of known issues causing Easy Anti-Cheat blue screens with “MEMORY_MANAGEMENT” errors.

​On Tuesday, Redmond released security updates (KB5060842 and KB5060999) for 66 vulnerabilities in Windows 11, including a publicly disclosed Windows SMB privilege escalation flaw (CVE-2025-33073) and an actively exploited Web Distributed Authoring and Versioning (WebDAV) zero-day (CVE-2025-33053).

The July 2025 Patch Tuesday Windows updates addressed ten critical vulnerabilities, eight allowing attackers to gain remote code execution on unpatched devices, and the other two enabling them to escalate privileges.
