What's wrong with Windows EFS (encrypting file system)?

Command-line, cipher /e on a fresh directory, or cipher /e /s:<dir> /a
to encrypt existing tree in <dir>.

Only available in >Home editions AFAIK though. Be sure to back up your
crypto private key using the certificate manager (Start | Run |
certmgr.msc | Trusted People | Certificates, select key and right-click
+ Export).
