Since OSConfig isn’t segmented by Operating System Architecture, all Settings are applied to the OS. If you need to apply a Setting to a specific Architecture only, simply name the file with x86 or x64. OSConfig will only apply the appropriate file. In the example below I had two files (x86 and x64). Only the x86 was applied to my Windows 10 x86 deployment, while the x64 version of the file was moved to C:\Windows\OSConfig\Settings\NotApplicable . . . and the OSConfig.log reflects this as well.
