Drive Letter Assignments Reverting after Reboot

Topic says it all. In my setup, I prefer the CD and DVD drives to be assigned drive letters at the end. I assigned "Z" to my built-in laptop DVD ROM drive, and "W" to my Alcohol 120% virtual drive.

The problem with this is, the drive letters revert to E: and F: respectively, after a reboot. I have tried uninstalling the drivers and disabling the virtual drive. I also tried logging in as "Administrator", and changing the settings, but the changes do not stick. The new assignments are only valid right between the time I changed the drive letters up until the next reboot.

Help?

Jam it back in, in the dark.

Correct. I wouldn't know of any easier way to do this.

I change it via Computer Management applet under Administrative Tools, but the change doesn't stick past shutdown.

There's nowhere I can't reach.

Bump. It's still happening. Anybody?

I could always surrender and leave Drives E and F free for these recalcitrant drives, but I don't wanna

This thing is sticky, and I don't like it. I don't appreciate it.

BIOS has no such setting, I'm afraid. Nothing untoward in the Event Log either.

Uninstalling the emulation software and switching drive letters were futile as well, unfortunately.

I did notice that certain external drives kept the reassigned drive letters, while the internal one didn't. I guess I lose I don't know what the heck is going on, why the heck it is going on, and I don't wish to reformat just to be able to rearrange drive assignments at my leisure.

At any rate, guys, I appreciate the recommendations!

I've uninstalled my NVidia drivers, and updated to 9792 with a modified INF from LaptopVideo2Go. For now, it seems to fix the problem.

As per foxfire55423's posts, updating drivers only work for a few days, so I'm keeping my fingers crossed! Thanks for the heads up, at any rate!

I was speaking idiomatically.
