    I installed Virtualbox and it changed the file association for VHD files.  I tried changing it back by setting Windows Explorer as the default for Open With... but I don't get the Drive Tools tab in the ribbon when selecting a VHD.  The Open With... dialog did not show Windows Explorer as an option so I had to browse to c:\windows\explorer.exe

    The same thing happened with ISO files when I installed ImgBurn but I changed it to open with Windows Explorer and that fixed it -- the Open With... dialog DID show Windows Explorer as an option.

    Double-clicking a VHD results in the mouse cursor flickering between the normal cursor and cursor with hourglass, until reboot.

    Any idea how to repair this?

    I was able to compare registry entries after I installed Windows 8 on my laptop, here were the changes I made that fixed the problem.

    Changed this key
    [HKEY_CLASSES_ROOT\.vhd]
    @="progId_VirtualBox.Shell.vhd"
    "Content Type"="application/x-virtualbox-vhd"

    to this
    [HKEY_CLASSES_ROOT\.vhd]
    @="Windows.VhdFile"



    Changed this key
    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vhd\OpenWithProgids]
    "progId_VirtualBox.Shell.vhd"=hex(0):

    to this
    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vhd\OpenWithProgids]
    "Windows.VhdFile"=hex:



    Delete these keys
    [HKEY_CLASSES_ROOT\progId_VirtualBox.Shell.vhd]
    @="Virtual Hard Disk"

    [HKEY_CLASSES_ROOT\progId_VirtualBox.Shell.vhd\DefaultIcon]
    @="\"C:\\Program Files\\Oracle\\VirtualBox\\VBoxRes.dll\",-305"

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vhd]

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vhd\OpenWithList]

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vhd\OpenWithProgids]
    "Windows.VhdFile"=hex(0):

    [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.vhd\UserChoice]
    "Hash"="ph3EwuI1Lc0="
    "Progid"="Applications\\explorer.exe"

    Hi,

    Please create a new VHD in Disk Management and see if it can be attached bu double-clicking it.
