If you have countersigned the signature with a trusted timestamp signing authority (e.g. VeriSign's timestamp authority), the signature will remain valid after the signing certificate has expired, so long as the countersigned timestamp is before the signing certificate's expiration date. IOW, as long as you signed the file while your cert was not expired AND timestamped it with a countersigned timestamp, it'll still be good.

Hey All,
Quick question about driver signing. I hope this is the correct forum
for my question.
I have a device driver for an external PNP device. I am currently
signing it and will be shipping it out in my next software release
targeting windows vista. I understand that signatures do expire. I'm
uncertain if the signature on my signed drivers expire (they do
expire, don't they? Where can I find the expiration date?).
Furthermore, what will happen when the drivers expire? The drivers, I
assume, will still work with the device after the drivers expire,
correct? What happens when a user tries to install my device drivers
after they expire? Do they just get a notice that the drivers have
expired?
Thanks in advance,
Matt
