Autoruns 13.30

Autoruns is the best system tool for maintaining your startup programs.
It can show you every startup programs of windows. These programs include the ones in your startup folder, Run, RunOnce (programs configured to run only once, like a setup program), and other Registry keys. It also has the feature of showing Explorer shell extensions, various toolbars, browser helper objects (BHOs), Winlogon notifications, auto-start services, and much more. This is a really great program.

It shows the critical windows processes, the DLLs, etc and all of these entries can be deleted by this program! So, it is really easy to remove some programs, like if some spyware has installed a toolbar in Internet Explorer, that can't be uninstalled.

The scheduled tasks section shows entries that are actually hidden from us. So, this one has the ability to manage all the system properties, and processes. So, you must be careful while using it, since removing some entries may stop windows from starting up.

The "KnownDLLs", "Winlogon", "Winsock Providers", "Print Modules", "LSA Providers", "Network Providers", "Vista Sidebar Gadgets", "Image Hijacks", etc are some sections, and there are many more; even if this program is really small, its capabilities are more.

It also has a properties page that is generated for any item in the startup.
It has a process explorer, which can be used to monitor the CPU, memory usage, just like the task manager, only with some more capabilities.
