Autoruns – What is Running on Your Windows 7 PC

If you have wondered what programs are automatically configured and
loaded when you startup, Autoruns, by Microsoft will give you that
information. Autoruns is an MS download program that will show you
locations, and startup order of many programs. It will provide you with
information about Explorer shell extensions, and toolbars, as well as helper
objects, auto-start services and Winlogon.
What does Autorun provide?
It shows you the currently configured auto-start applications
The full list of the Registry settings used.
File system locations used for auto-start configuration.
There are 18 tabs that can focus your attention to individual performance or configuration
options.
It is a configuration tool that can be used by administrators to monitor and
tweak the performance of the system. There are multiple tabs to work with.
Here is the Logon tab which contains information about what programs load
at logon.
Another important component is that it allows you to see third party
auto-starting programs. Through Autoruns’ Hide Signed Microsoft Entries
option you can see third-party programs that have been added to your
system.
If you prefer the command-line equivalent you can run Autorunsc from the
command prompt which is automatically included in the download package.
The output result is in CSV format.
There are a number of command switches that can be used with AutorunSC:
autorunsc [-a] | [-c] [-b] [-d] [-e] [-g] [-h] [-i] [-l] [-m] [-n] [-p] [-r] [-s] [-v] [-w] [-x] [user]
