Description
Control of credentials and the system must be maintained within the enterprise. Enabling this setting allows enterprise credentials to be used with modern style apps that support this, instead of Microsoft accounts.
ℹ️ Check
Windows 10 LTSC\B versions do not support the Microsoft Store and modern apps; this is NA for those systems. If the following registry value does not exist or is not configured as specified, this is a finding. Registry Hive: HKEY_LOCAL_MACHINE Registry Path: \SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\ Value Name: MSAOptional Value Type: REG_DWORD Value: 0x00000001 (1)
✔️ Fix
Configure the policy value for Computer Configuration >> Administrative Templates >> Windows Components >> App Runtime >> "Allow Microsoft accounts to be optional" to "Enabled".
