Installed it. Rebooted, then looked at Autoruns. It's quite comprehensive in its report. So much so that I don't know what it is exactly that I am looking at or for. Perhaps you can elaborate some.
There are numerous tutorials and video's online for Autoruns.
It isn't possible to give a detailed walkthrough here of why Autoruns is so useful but I can give some short comments about it.
There are many tabs in the applet, the key ones for me are:
Logons: Mostly shows apps that start during Windows bootup. Good for finding unwanted apps that are starting up during bootup.
Services: Lists all the Window services that are enabled during bootup.
Drivers: Which drivers are enabled during bootup. Very useful if there are driver issues during bootup (e.g. BSOD's caused by drivers at startup time)
With any entry it is possible to right click it in Autoruns and select the
Jump to Entry... option on the menu and it takes you straight to the Registry Editor (Regedit) for that item. Selecting the
Jump to Image... option opens up File Explorer in the folder where the relevant system file is located.
Another use it has is for tracking down malware at bootup time.
Unticking any app, driver etc. stops it from starting at bootup
(discretion is advised when doing this).
