W8 unauthorized access to registry files on my secondary hard drive

May be difficult to believe, but... I'm doing another Windows 8
installation on a blank hard drive (not really blank, I know, but the
drive was "deleted" and stuff). Installed as the official
Administrator, in order to have write access to files on my secondary
hard drives. Just starting, after some basic configuration, I enabled
Windows Speech Recognition. Then went to sound properties. That's
where the default sound scheme is supposed to be. Instead, I'm
looking at a sound scheme that has a personal label I made in a prior
installation of Windows. So I'm wondering where on earth that sound
scheme label came from. One explanation is that for some strange
reason Windows 8 decided to look at registry files on my secondary
hard drive, to see if there were any sound schemes that I had saved.
I doubt I would believe that if somebody else told me. I started this
installation two hours ago. I had not even looked at sound
properties. So of course I did not make that sound scheme label in
this installation. Also sort of strange is that the backup registry
files on my secondary hard drive do not completely spell out the
sound scheme name, since it's over eight characters.

The only other explanation I can think of would be that Windows 8
accessed some hidden stuff on my secondary drives. Those drives were
disconnected during the installation, but reconnected after the
installation finished. Or maybe it didn't actually delete the stuff
on the primary hard drive, for the purposes of doing a clean
installation. Still, setup indicated that the drive was blank, and it
looked exactly like a clean installation.

I can repeat the installation. I really don't see how that can happen
legitimately.

I made reasonably sure that Windows 8 formatted the SSD. The other
drives were disconnected during the install. I didn't check until
after reconnecting the secondary drives (I really didn't think it
would happen again). Same thing.

I will have Windows 8 format the SSD again, and then check before
reconnecting the secondary drives.

BTW... Of course I'm not suggesting there is some evil movive for
adding a sound scheme.

Oh brother. This was a major oversight on my part.
Nevermind.
