When you encrypt files in Windows 7, it requires an encrypting file system (EFS) certificate which is issued to you by Windows 7. A recovery certificate is a special EFS certificate you can use to recover encrypted files if your encryption key is lost or damaged. You can create a recovery certificate very easily. Here is how :
