What are install* eula* and hash code directories sitting on the root of my drive?

Question

I get these all of the time. I am guessing they are Windows Update, but why they are writing to the root of my secondary hard drive I do not know. The partition is not marked as a system partition. Any idea what these are and how to get rid of them permanently?

Solution

Those are from the Visual C++ 2008 Redistributable package. That's a little mistake on Microsoft's part, they were supposed to be written to the temp directory on the C drive, but instead they end up being written to the root of whichever drive has more free space. They can be deleted.
