Thank you for letting us know about the issue that you encountered. I have created a support ticket for you to further investigate on the issue of the updates. Regarding your question about the difference between the ITSM Patch Management and the Patch Management, when it comes to functionality they are the same, the difference is that the Patch Management under ITSM is integrated with the ITSM portal and client software and the PM standalone is only dedicated to the PM functionality only.
