Without the certificates, they're gone forever. I was stung by this
initially and lost part of a short story I was writing (thankfully not
too much of it). I hadn't realising the encrypted data was so tied to
the current OS installation and would be irretrievable upon a
reinstall of WindowsXP Pro.

It's a ridiculous situation really: that a hand-holding OS like Windows
doesn't warn you of the consequences whenever you encrypt a file. When
you generate GPG (the free alternative to PGP) keys to sign or encrypt
data, you are warned that you must back up your 'keyring' to external
media, just to protect yourself from irretrievable loss of data.
WindowsXP does nothing like this, and as a result, you'll find squillions
of posts on Usenet from people distraught at losing anything from a few
files to an entire partition. Merely because they checked a box so
easily without realising the consequences.
