You must be logged on as an administrator to perform these steps.
You can use Certificate Manager to see details about your certificates, modify them, delete them, or request new ones.
Open Certificate Manager by clicking the Start button , typing certmgr.msc into the Search box, and then pressing ENTER.
If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Certificates are stored in the folders under Certificates - Current User. You might have to search through the folders to find the certificate you're looking for.
When you open a certificates folder, the certificates are displayed, along with some details about them, in the right pane. The Intended Purposes column tells you what each certificate is used for.
You can request a new certificate with the same key or a different key, and you can also export or import a certificate. To do any of these things, click the certificate, click the Action menu, point to All Tasks, and then click the command that corresponds to what you want to do.
