Thats not needed, if you read 1 post before yours. VSP1CLN.exe is part of a Vista SP1 (asuming you installed SP1,otherwise this file isnt even needed) Its present in system32, so after sysprep open a cmd and fill in : VSP1CLN.exe , and hit enter , it asks if you want to do it Yes or NO So no need to download that file. I made a screenshot of it, i know its dutch , but i hope you can figure it out. This is right before i close the system from audit mode.
