Problem: You want to launch the Lite Touch wizard from MDT 2010 and use it to perform a completely automated Refresh deployment from Windows XP to Windows 7. You've removed the deployment type setting from your CustomSettings.ini file, and you've configured all the skip settings to No. You then run LiteTouch.wsf with the command-line options /DeploymentType=REFRESH and /SkipWizard=YES, but the Lite Touch Wizard is still displayed.
Resolution: Your syntax is incorrect. Replace the equal signs in these options with colons (i.e. /DeploymentType:REFRESH and /SkipWizard:YES) and the Lite Touch Wizard should not be displayed.
