A friend of mine sent me an email today with a link to an article stating how NSA access was built into Windows.
Although, it seems that this news is quite old, I only heard from this today. In my opinion, it is very scary that there are master keys for the encryption in Windows. This means that the NSA can look into your encrypted data at any time.

Now, while that may be handy for the NSA, what would happen if a disgruntled employee of the NSA/Microsoft dropped this ‘magic’ key on the black market. Suddenly anyone willing to pay for it could decypher your precious encrypted data. Scary stuff.

So, my suggestion is not to use the MS implementation of Encrypted File Systems but go with Open Source solutions like TrueCrypt . At least for the OS soft, the code can be reviewed by others.
