Summary: ArcGIS patching is too limiting with the Patch Notification tool and automatic service starts should not be required.
1) The patch notification tool should have a setting to not restart services after patch/es are applied. This is desirable for installing multiple patches. Starting the service between patches makes the patch process take much longer with multiple patches.
2) When manually installing patches via MSP file and msiexec, a property should be available to pass on the command line to not have Widows ArcGIS service/s started after the patch is applied. Related to #1, this will allow admins to more efficiently patch in the least amount of time, as service starts are not necessary to patch application files.
