    Thanks, incorporated this into my deployment.

    It went okay on my technician machine. On my test machine, a new build in audit mode, it said it could not run in safe mode. I am not sure what to make of that. Any ideas?

    • Scott Mitchell

      Found the answer to the above question: Turn off System Protection to run the command in Audit mode. Do this: In the search box type: ‘create a restore point’ then open it. It opens the System Properties dialog box. Under the tab System Protection, select ‘Configure…’ then select ‘Turn off system protection’. Now runs the command (the cleanup takes several minutes), when it’s complete uncheck ‘Turn off system protection’.
