This is a great Freeware program that allows you to view all of the programs that are launching when you boot your PC.

CodeStuff’s Starter program is one I have kept around for awhile now. There is a new(er) update available (v5.6.2.8) and it works on my Vista machine.

Download, setup and run this little ditty to take control of which applications deem themselves worthy of launching every time you rev up your box. This program runs deep showing more than meets the eye:

From their website

As a primary purpose, Starter allows one to view and manage all the programs that are starting automatically, whenever [your] operating system is loading. It enumerates all the hidden registry entries, startup folders’ items and some of the initialization files, so that [you can] choose to temporarily disable selected entries, edit them, create new, or delete them permanently.

[The] Secondary purpose is to list all of the running processes with the possibility to view extended process information (such as used DLLs, memory usage, thread count, priorities etc.), and to terminate selected process (even a Windows NT service, having enough access rights).
