The Software Update Point (SUP) role is used to deploy software updates to SCCM client agents. If you want to move the SUP role from one server to another, or are decommissioning a SCCM site, you may need to remove the SUP role. You can remove the SUP role using the SCCM console, or by running the command below:
e:Program FilesMicrosoft Configuration Managerbinx64rolesetup.exe /deinstall /siteserver:sccm01 smswsus
Upon running this command, you should see the following appear momentarily in your SUPSetup.log file:
