I want to set the volume name of my network redirector.
On 32bit Windows, it's okay. I made it.

But on 64bit Windows7, a process which runs as WOW64(eg, EXCEL.EXE) finds following registry path to represent the volume name when we open a file dialog. -I checked it by Process Monitor.

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoints2\{0D8551B0-3A13-4C6F-816A-CE8F7AE129B8}\_LabelFromReg

If I set the value, yes, the Wow64 application represents volume name as well.
If not, only "Disconnected Network Volume" is displayed.
But I don't know the GUID value when I connect a network volume.

What does '0D8551B0-3A13-4C6F-816A-CE8F7AE129B8' mean?
And How can I get the value of my network redirector.

Edit:
Only Wow64 apps cause the problem. Windows Explorer doesn't, because it has been ported to 64bit.
