File security warning C:\Windows\System32\osdsetuphook.exe

You may receive File security warning for C:\Windows\System32\osdsetuphook.exe when running SCCM OSD task sequence.

You most likely will get this message in OSD Results and Branding stage.

In my observation, you receive open file security warning, when the task sequence is set to run 'Access content directly from a distribution point when needed by the running task sequence'.

If you change this option to 'Download content locally when needed by running task sequence', the open file security will go away and the task sequence complete without any msg.

 We can address this issue in multiple ways;
     - Change the deployment options as mentioned above
     - Disable the open file security and then re-enable at the end
     - Copy the scripts locally, then launch the scripts using the local paths
