Too Many Steps? Help!

on Disinfection by ****

I just d/l the adwcleaner step 1 with no issues and i notices there's a bunch more steps. Are they necessary? I only have Windows Defender that comes with windows 10. Obviously i wouldn't do steps that say optional or for apple when i have a hp but the other ones that say hitman pro for example. A small window popped up after the scan saying to enable detection of PUPs on adware...where do i do...
