Re: Digital signature
You get "digital signature" warnings for two possible cases:
(A) Installing unsigned kernel-mode drivers. You can't actually install
unsigned kernel-mode drivers on Windows Vista x64, so this warning is fatal.
(B) Running applications that are prompting for administrator elevation. The
prompt itself is (1) blue for a Microsoft Windows code signature, (2) grey
for a non-Microsoft signature, or (3) yellow for unsigned.
Note that there is no "Microsoft registration" happening here. The publisher
of any given piece of software is free to sign it themselves directly. This
is essentially the same technology used for "https" websites. In both cases,
the company buys a certificate from a 3rd party vendor that will validate
it's really them. If you are installing random software off the Internet or
open source software without a company affiliation, then there's no way to
know if the software is what it claims to be or something designed to steal
your password and information. At that point, it's up to you. At least with
the prompt, you can try to make some kind of guess.
