I need specific instructions on recovering a windows 10 password on another computer
Not sure what this has to do with Avast - at first I suspected spam and was looking for a hidden spam link

So I did a search on what you asked "recovering a windows 10 password on another computer" and that returns many hits, some not so specific.
There is even one from Avast.
