Windows 7 Certificate Manager
As an administrator, you have the permissions to view or manage the certificates. If you not logged in as an administrator, you must log off and log in again. The Certificate Manager will allow you to see the details about your certificates, how to modify them, or delete them, or even to request new ones.
Here is how it works: You can open the Certificate Manager by clicking the Start button, typing certmgr.msc into the search box, and then pressing enter. You may be prompted for password or confirmation. If so, type the password or provide confirmation.
When you open the certificate window, the certificates will be displayed, and information about them, in the right pane, will be described. The Intended Purposes column identifies what each certificate is used for. Requesting a new certificate with the same key or a different key is possible. (Keys are encryption devices that are frequently furnished for you automatically.)
You can also export or import a certificate. But whatever action you want to perform, the steps are the same; just click the certificate, click the Action menu, pursue the All Tasks, and finally click the command that identifies what you want to do.
