Administrative credentials are mandatory for executing Sysprep when capturing a Windows 10 image. If the 'User' credentials field exceeds 20 characters, the task will fail to save and Sysprep will fail to execute.
1) New 'Create Disk Image' tasks will disappear from the job when attempting to save them.
2) Existing 'Create Disk Image' tasks will not retain the new credentials and revert.
The cause of this issue is currently under investigation.
