Windows doesn't really use labels, but there is a local volume GUID:

$ mountvol	# lists all volume paths \\?\Volume{...}\
$ l /proc/sys/GLOBAL\?\?/Volume\{...\}/
'$Recycle.Bin'/             PerfLogs/               swapfile.sys
'Documents and Settings'@  'Program Files'/        'System Volume Information'/
 hiberfil.sys              'Program Files (x86)'/   Users/
 OEM/                       ProgramData/            Windows/
 PageFile.sys               Recovery/
$ l /proc/cygdrive/d/
'$Recycle.Bin'/             PerfLogs/               swapfile.sys
'Documents and Settings'@  'Program Files'/        'System Volume Information'/
 hiberfil.sys              'Program Files (x86)'/   Users/
 OEM/                       ProgramData/            Windows/
 PageFile.sys               Recovery/
$ cmd /c 'dir /a \\?\Volume{...}\'
 Volume in drive \\?\Volume{...} is LABEL
 Volume Serial Number is XXXX-XXXX

 Directory of \\?\Volume{...}
