Delete a self-signed digital certificate

[skchow]

I've created a self-signed digital certificate as follow step:
Start button-->Microsoft Office-->Microsoft Office Tools-->Digital Certificate for VBA Projects.
1.How to delete the self-signed digital certificate after created?
2.How to change the expiration date for the self-signed digital certificate?

I'm assuming that the certificate didn't work which is why you want to delete it...

More info on what you want to accomplish.
