Updated FAQs with the following information: To address a known issue on systems with dual booting for Windows and Linux, we have reconfigured the manner in which this fix can be applied. Starting with the September 10, 2024 security updates, the fix will not automatically apply the SBAT update to the firmware. Customers who have applied the August 13, 2024 security updates will have the SBAT update in firmware and will be protected. Customers who have devices with Windows system only and who have not applied the August updates and who want to be protected from this issue can either apply the August 13, 2024 updates or apply the September 10, 2024 updates and set the following registry key from an Administrator command prompt: `reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Secureboot /v AvailableUpdates /t REG_DWORD /d 0x400 /f”`
