I added a new 4TB hard disk drive to my desktop computer, and noticed a couple of days later two .dll files at the root of the drive.
The environment in question is a 64-bit Windows 7 Professional (American English, if that matters). This new hard disk does not contain the OS (the OS is on a separate SSD disk). I have not installed any applications to this new hard disk.
Being that the OS is on a separate disk, what would be the reason for some process to place dll files on the root of the new HDD?
