Moved provisionally to VSE for better support.
This batch file creates a list with all file names that look like "scriptsn*.dll" from the "C:\Program Files\Common Files\McAfee\SystemCore\" folder. It will then register the .DLL files using regsvr32.exe. When that is done it will stop and restart the system center management service.
Thank you Johma, basicly what you did there is just explain the script, I could have also done it
This was more the answer I was looking for:
The unregister.cmd script was created to de-register an old scriptscan dll due to a memory issue that was resolved by Patch 2 for VSE8.8. This task can safely be removed as so long as the customer is on VSE 8.8 Patch 2 there is no need for this task.
