MDT 2010 failure during sysprep and capturing

I am using MDT 2010 to do a sysprep and capturing task sequence on the Windows 7 reference machine.

First of all, I mapped the deploymentshare$ to drive Z. After that, I execute the Litetouch.wsf file under the deploymentshare$\script and then go thru the wizard. Everything run smooth until the sysprep finished, a failure occur like the screenshot below.

This failure happened due to the registry key CloneTag under HKLM\SYSTEM\Setup is deleted during the start of the sysprep. There are few ways to counter this failure:

• Go to your sysprep and capturing task sequence, Execute Sysprep, Options tab, Add, Registry Setting. Enter SYSTEM\Setup in the key box, and enter CloneTag in the value name box and leave the value box blank. This whole step is to add the registry key back to HKLM\SYSTEM\Setup after the sysprep completed.
• You can also modify the script to prevent the registry key from being deleted. Go to your deploymentshare folder and look for a script named LITSysprep inside the scripts folder. Right click, edit to do modification in the script. You can either remove the oShell.RegDelete "HKEY_LOCAL_MACHINE\System\Setup\CloneTag" or you might want to add .// infront to turn it into a comment.

Both ways stated above can resolve the failure occur during sysprep and capturing. This topic also discussed in technet forum, and here's the link.
