Certificate revocation is a feature that automatically verifies the status of a certificate with the Certificate Authority. If the certificate has been revoked because it has been compromised, you should be informed immediately. This feature is enabled by default. Microsoft recommends that you do not disable this feature because it protects you from fraudulent digital certificates. However, if you decide to turn off this feature, you can use Internet Explorer, as shown in Figure 2.

Follow these steps to turn off this feature:
Start Internet Explorer.
Go to Tools, Internet Options, and select the Advanced tab.
Uncheck the box Check for Publisher's Certificate Revocation under the Security section, and click OK.
For security reasons, I recommend that you leave this feature enabled.
