Codesign for Windows

I usually say “I dont need that and I dont want to be rude so I am letting you know I am going to hang up now”
Whether they are / are not done with the speil
Then I hang up

It is close to a year now and my Comodo codesign cert is expiring Nov-19, 2016. Although I recvd a email reminder from KSoftware, I waited until today to order new cert (they don’t do renewal) and I just recvd email to collect the new cert (quite fast - 8 hours).

Since this is my first time “crossing over” from the expiry of old cert to new cert, I think I better ask some questions and hopefully tap the knowledge of those who have been there before.

The questions are:

What happen to those exe/installer I codesigned with the old cert when it expires Nov-19, 2016?
Will there be problem?
Is it necessary to codesign them again with the new cert?

Thanks for all help and advice.

All the executables you have signed before remain protected.

Thanks!

I supposed there won’t be any frightening message that the codesign cert is invalid or expired? Nothing that will cause alarm?

I have executables signed years ago, they do not show frightening messages.

Thanks very much.
