If you are backing up the certificate through the EFS balloon/prompt/wizard,
there is no need to select options. The default settings are all that you
need. If you are backing up the certificate from Certificate Manager's
Export Wizard, be sure to select "Yes, export the private key." It's best to
store the backup (the .pfx file) on removable media in a safe location and do
not encrypt that file. The EFS balloon will go away after three logons if
you make no selections in the prompt or if you choose to not back up (not
To determine the date that the first encryption occurred, open the
certificate in Certificate Manager and click on the Details tab. It will
have the "Valid from" date in the listview. That is the date the certificate
was created. Perhaps you can recall what occurred on that date that might
have done an encrypt operation. The only other "under the covers" encrypt
operation that we know of is when "Encrypt your offline files" is enabled.
