Backup Windows Current User / Personal Certificates to a .zip

See more Certificates Examples

Demonstrates how to backup the certificates in the Windows registry-based Current User certificate store (in the "Personal" Logical Store as seen in certmgr.msc), to a zip archive. Certificates having an exportable private key are exported to .pfx files. Certificates with no private key, or with a non-exportable private key, are exported to .cer files.

Obviously, this example only runs on Windows computers.
