Our organization has recently received a number of Tablet devices (over 100) which we require a standardized image to be deployed to them all, the obvious thing to this was to create a standard image using sysprep however when i run sysprep I get the message 'Sysprep was not able to validate your windows installation' and to check the logs when i check the logs i find a message saying 'sysprep will not run on an upgrade OS' I have recently updated to windows 8.1.
I have found an article relating to windows 7 which suggested deleting the 'upgrade' key from the registry however this solution has not worked for windows 8.1
Can someone help? I do not have the time nor patience to have to start the image from scratch.
Thanks
Kev.
