Enable exFAT in Windows XP/2003

To enable exFAT (which is a new file system type introduced by Microsoft in Windows Vista), you need to copy the two files uexfat.dll and exfat.sys located under System32 folder and System32/Drivers folder into correspond folder of Windows XP/2003

Create the following registry file "enable-exfat.reg"

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\exfat]
"Description"="exFAT File System Driver"
"DisplayName"="exFAT File System Driver"
"ErrorControl"=dword:00000001
"Group"="Boot File System"
"Start"=dword:00000002
"Type"=dword:00000002

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Eventlog\System\exfat]
"EventMessageFile"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,\
00,6f,00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,\
