In October 2024, Microsoft released Windows 11 version 24H2, introducing a suite of new features and enhancements. However, the rollout was accompanied by a series of compatibility issues that led to the implementation of upgrade blocks on certain systems. One significant issue involved the Easy Anti-Cheat (EAC) software, widely used in popular games like "PUBG" and "Fortnite," which caused affected systems to crash with a "MEMORY_MANAGEMENT" error, resulting in a blue screen of death (BSOD). This problem primarily impacted devices equipped with Intel's Alder Lake+ processors and the vPro platform running EAC drivers released before April 2024.
To safeguard users from these crashes, Microsoft placed an upgrade block on September 30, 2024, preventing affected systems from installing the 24H2 update. Over the subsequent months, Microsoft collaborated with Easy Anti-Cheat developers to address the incompatibility. By June 2025, an emergency update (KB5063060) was released to resolve the issue, and on July 24, 2025, Microsoft officially lifted the upgrade block, allowing previously affected users to update to Windows 11 version 24H2.
It's important to note that while the EAC-related block has been removed, other upgrade blocks remain in place for different compatibility issues. These include problems with Intel Smart Sound Technology drivers, applications that utilize integrated cameras, audio output issues on systems with Dirac Audio, and conflicts with the sprotect.sys driver. Users are advised to check for updates to their hardware drivers and software applications to ensure a smooth upgrade experience.
For those eager to upgrade, it's recommended to update any games that use Easy Anti-Cheat to the latest versions, as this may include compatible EAC drivers. Additionally, ensuring that all system drivers are up to date can help mitigate potential issues during the upgrade process.
As Microsoft continues to address and resolve these compatibility issues, more users will be able to take advantage of the features and improvements offered in Windows 11 version 24H2. Staying informed through official Microsoft channels and regularly checking for updates will aid users in navigating the upgrade process effectively.
