Associate an icon with a drive

To set the icon of any drive (hard disk, cd rom or anything else) with a letter (C:\ etc.), run REGEDIT (Start -> Run -> regedit)

Navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer

If one doesn't already exist, create a new KEY called "DriveIcons". Under this key, create a new key with the letter of your drive.

Best way to Hide the Recycle Bin from the Desktop

Open Regedit & explore:

if you are using the XP style start menu
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows

\CurrentVersion\Explorer\HideDesktopIcons\NewStartPanel\

if working with the classic menu:
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows

\CurrentVersion\Explorer\HideDesktopIcons\ClassicStartMenu\

Inside, Make new DWORD-Value with the name

"{645FF040-5081-101B-9F08-00AA002F954E}" & 'Modify' Value "1"

That will just hide the Recycle bin icon,
If a Dock is installed, by this procedure the 'Recycle bin' Docklet won't be

anyhow affected as by some other Tweaks.

To restore the desktop icon again, just 'Modify' the same DWORD-Value to "0"
