Before Sysprep OOBE, Delete User and files, add a new Administrator User with blank password
Also check BIOS OEM Key with Produkey. Windows (BIOS OEM Key) HNV26-68WWR-QV4PJ-WRJWT-GMRYC
After Imaging, had to change product key and put it in.

I usually find is that the default profile will be a bit bloated and contain some references that are not necessary (like PowerShell command history, for instance).
To get around this, I run the following script either during imaging or post-imaging just to ensure that the default profile is fully tidied up and as streamlined as possible.
takeown /f c:\users\default\appdata\local\Microsoft\WindowsApps /r /a /d Y
icacls c:\users\default\appdata\local\Microsoft\WindowsApps /grant Administrators:F /T /C /L
get-childitem C:\Users\Default\AppData\LocalLow -force | foreach ($_) {remove-item $_.fullname -force -recurse -confirm:$false}
