Change Drive Name and Icon (All Windows)

Download PDF

This tweak allows you to change the name and icon shown in Explorer for a specific drive letter. Open your registry and find the key below. If the key does not already exist then create it.

Within the main key create a new sub-key with a single letter representing the drive letter of the drive to be

modified. (e.g. [HKEY...\DriveIcons\D])

Within the drive letter key create another sub-key called "DefaultIcon" (e.g. [HKEY...\DriveIcons\D\DefaultIcon]) and set the "(Default)" value to equal the fully qualified name of the icon file. If the file contains more that one icon follow it with a comma and the zero-based index of the icon (e.g. "c:\icons\myicons.dll,4").

Create another sub-key within the drive letter key called "DefaultLabel" (e.g. [HKEY...\DriveIcons\D\DefaultLabel])

and set it's "(Default)" value to equal the label for the drive letter (e.g. "My ZIP Drive").

For example:

HKEY_LOCAL_MACHINE Software

Microsoft

Windows

CurrentVersion

Explorer

DriveIcons

D

DefaultIcon

(Default) = c:\icons\myicons.dll,4

DefaultLabel

(Default) = My ZIP Drive

You may need to restart Windows for the change to take effect, or press F5 to refresh My Computer.

Note: The "DefaultLabel" value only works with Windows 2000 and higher.

Settings:

System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\ DriveIcons]

Type: REG_SZ (String Value)
