I need having one installation UNATTENDED already activated. I have created my Unattended CD (OEM License) and I have execute an installation. After I have activate across internet (activation OK!) I have regenerate the Unattended CD with the WPA.DBL file in the $OEM$\$$\system32 I am using the Unattended CD on the same system that I got the WPA.DBL file from. After the install completes I am still prompted to activate windows (Why?). My question is: Is there something else we are supposed to do when backing up our activation other than just copying the file to the $OEM$\$$\system32? Do we need to add a reg tweak or a command in a batch file or something? I checked the guide but it doesn't say to do anything else. Where is my error? Thanks for any help or clarification you can
