msiexec noreboot option

whats wrong with this command as i dont want it to restart after it uninstalls sep but it restarts

start /wait MsiExec.exe /X {8097EE64-FDE1-409A-B25D-3DFD862871E1} /passive /norestart

Looks fine to me. You can copy and paste this script into a vbs file. It will silently uninstall SEP and not reboot. I use this at work to remove software. You can also edit the RemoveCurrentInstalls "Symantec Endpoint" to match any software for the future you need to remove.
