Spybot will let you know, as a fault, if you shut down some vital function in windows. When it does that to me, I go into "Settings > Ignore Products" and just put a check mark next to the item that I want Spybot S&d to ignore.
There are a lot of things that could be or should be done with Spybot that you just can't do if you don't set it up right in the first place.
My own setup routine for Spybot takes up a full page, in 10 point type.
It's important enough, that I even gave it space on my own web site.
That address is in my personal information page.
In looking through my own "Ignore Products" list, I did not see "WinSATRestorePower". A Google only pointed back to this thread.
If set up properly, Spybot will make a restore point before deleting anything. let it delete the questionable entry and if that causes you any problems, do a system restore and put it back.
I just ran Spybot S&D again and that "WinSATRestorePower" did not show up, so I'd have to say it's definitely something that should be deleted.
