1. Click "Start > All Programs > Administrative Tools > MyCertificatesConsole.msc". "MyCertificatesConsole" window shows up.

2. Open "Certificates (Local Computer) > Trusted Root Certification Authorities > Certificates" in the Console Root tree.

3. Select "Go Daddy Class 2 Certification Authority" and click "Properties" from the "Action" menu. The properties dialog box shows up.

4. Check the "Disable all purposes for this certificate" radio button.

5. Check "OK" to save the changes.

The Go Daddy certificate is disabled now. Note that applications, like IE, that uses certificate stores will not be able use this certificate now.
