Software Explorer isn't included in Windows Defender in this version of Windows because it's not integral to spyware detection and removal. To see all of the programs and processes that run when you start Windows, you can use Autoruns for Windows, a free tool that you can download from the Microsoft
website. You can also use Autoruns for Windows to stop a program from running automatically when Windows starts by clearing the check box next to the name of the program. Autoruns for Windows is designed for advanced users.
