What are tiny black insects looking like specs of soot with six legs segmented body two antennae and microscopic white hairs all over its body that appeared on my window sill this winter?

Since no one else answered the question I was asking I will take a stab at it myself. I have had occasion to study them further and in greater detail. The first clue was the microscopic forked structure I observed on their underside attached to the3rd abdominal segment. I now know this to be the "furcula" and the mysterious bug to be a Poduromorpha variety of springtail. The furcula is the little structure that they use to jump with. The real clue was when I put some lemon oil onto the Windowsill in an attempt to discourage them. As the little bugs encountered the oil they were observed exhibiting a hopping behavior. I then googled springtails and there they were. I guess my Biology minor in college has come in handy after all.
