So I went to remove a program from startup today on a Server 2012 machine and typed in msconfig like I always have and received this error “Startup items are not enabled on this system.” In Windows 8 you can use task manager but not true with 2012. my googling has been unsuccessful so far. I know you can use a third party tool or edit the registry directly.
You can also check these folders: %appdata%\Microsoft\Windows\Start Menu\Programs\Startup and folder %ProgramData%Microsoft\Windows\Start Menu\Programs\StartUp
Here is the sysinternals tool.
I’ll post back if I find a better solution. “not enabled” leads me to believe you can enable it…
