If a control has a digital
signature, it means that the control has not been
tampered with and is guaranteed to be exactly the same
as when the software publisher created it.

C'mon!  This is assuming a secure PKI implementation, where you are assured
that the Private Key  has been maintained securely, and actually used by the
party it was issued to.   Microsoft's 'Authenticode'  has emphatically
failed to meet this description, ashas been demonstrated a number of times.
The most dramatic with the distribution of compromised components, signed -
apparently - by Microsoft (!!) with a legitimate but falsley issued key.
All the more disastrous, as MS left out a certificate -revocation mechanism
for 'Authenticode!'
