Specifies behavior for manifest lookup.


/ALLOWISOLATION causes the operating system to do manifest lookups and loads.

/ALLOWISOLATION is the default.

/ALLOWISOLATION:NO indicates that executables are loaded as if there were no manifest, and causes EDITBIN Reference to set the IMAGE_DLLCHARACTERISTICS_NO_ISOLATION bit in the optional header's DllCharacteristics field.

When isolation is disabled for an executable, the Windows loader doesn't try to find an application manifest for the newly created process. The new process doesn't have a default activation context, even if there is a manifest in the executable itself or if there is a manifest that has the name executable-name.exe.manifest.
