There are several methods to do this Microsoft's own msconfig.exe goto the run menu and type msconfig, is one that I still tend to favour however Mike Lin's StartupControlPanel
work just as well with the added bonus of a recycle bin
has a list of all unnecessary startups on their website for information only it will tell you which ones you have just remove then if you don't have any in their list you will get the following screen
The one problem that you may have is CTFMON.EXE it will keep returning not matter what it is the Microsoft process that controls Alternative User Input and the Office Language bar. It’s how you can control the computer via speech or a pen tablet, or using the onscreen keyboard inputs for asian languages.
If you really want to disable it unregister the DLL's that control it run these two commands in the start menu run one at a time you will receive confirmation that if has been done in a Regsvr32 window like the one below
Regsvr32.exe /u msimtf.dll
Regsvr32.exe /u msctf.dll
Reboot your computer and then open a Microsoft Office application if you do have that installed. Verify that ctfmon.exe is not running using Process Explorer
from Sysinternals the best alternative to the Windows Task Manager.
