In XP, your encrypted files would be lost if you changed your password.
Thankfully Vista reminds you immediately after the first time you encrypt a file.
Select “Back up now” from the wizard screen.
You’ll have to enter a password for the key.
This password will be used if you try and restore the encryption key later.
verify you choose a good password, and verify that it’s also something you’ll remember.
This is where a password safe tool might help.
Hit next and then finish, and you should see that the export was succesful.
Now it’s very important to back that file up to somewhere safe.
A spare USB drive wouldn’t be a bad idea.
…verify that you back up the key file safely.
