Mystery Folders

I have had 3 folders appear on my machine over the last few weeks. I can't
delete them; they exes/dlls all are in use. I suspect they are related to
Windows Update. Does anyone have any idea how to figure out what they are?
Here is the info on the folders:

97a9f41fab33a3dc4f45b1424fb18eb4
Volume in drive M is Mathis
