Sysprep.inf not deleted

[BINZA@]

I have used sysprep.inf file to deploy images to my users pcs which has
worked fine it uses mini setup and only prompts for pc name during install.
However I have just discovered that the sysprep.inf file has not been
deleted automatically as I thought it would be on deployed pcs, this is a
concern as the details of the account used to add pc to domain is in clear
text for all to see.

Why can this not be encrypted like the local admin is?
Why is the sysprep.inf not deleted after clone?

The path used is as recommended c:\windows\sysprep

Thanks for any help with this.

Found problem.
The sysprep folder should be directly under c:\ drive not under c:\windows.
