Microsoft released an emergency update, KB5063060, to address a compatibility issue causing unexpected restarts and blue screen of death (BSOD) errors on Windows 11 systems using Easy Anti-Cheat. This update follows the earlier cumulative update, KB5060842, which led to reports of system reboots linked to IRQLNOTLESSOREQUAL BSODs. The issues were confirmed to affect devices running Easy Anti-Cheat, which is used in popular games like Fortnite and Apex Legends. The update will install automatically for devices with Easy Anti-Cheat, and manual installation options are available for x64 and arm64 systems. Additionally, Microsoft implemented a compatibility hold for Windows 24H2 upgrades on Intel Alder Lake+ and vPro systems due to related blue screen issues. On the same day, Microsoft also released security updates addressing 66 vulnerabilities in Windows 11, including critical flaws in Windows SMB and WebDAV.
