Windows 8 Certificate storage

[eager2learn]

In cmd.exe after the command "net use W: \\192.168.0.52\data" I get a window with title "Certificate selection".
Where and how is a certificate stored in Windows?
As a file with a .crt suffix, in the registry or other?

They're stored as binary blobs in the registry.
User specific are HKEY_CURRENT_USER\SOFTWARE\Microsoft\SystemCertificates
> Group Name > Certificates
Localmachine are HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates
> Group Name > Certificates
