Question

Is there a registry key to tell windows to delete a file at next startup?

Answer 1

Yes, the values are stored in the registry key

HKLM\System\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations

but you'd better use a tool for this, like MoveFile from SysInternals, or MoveLatr from BitSum (C source code provided for the latter), which do the registry editing for you.
