that 811833 looked promising when I saw it before.
but,
here's the catch
windows 7 - isn't mentioned in this Notes:
Vista and Sever 2008 are. I hate to assume - is there something that states W7 is also 256 AES or better?
...
Notes
By default, EFS on Windows XP RTM uses the DESX algorithm. If you enable this setting, EFS uses 168-bit 3DES encryption.
By default, in Windows XP Service Pack 1 (SP1), in later Windows XP service packs, and in Windows Server 2003, EFS uses the Advanced Encryption Standard (AES) algorithm with a 256-bit key length. However, EFS uses the kernel-mode AES implementation. This implementation is not FIPS-validated on these platforms. If you enable the FIPS setting on these platforms, the operating system uses the 3DES algorithm with a 168-bit key length.
In Windows Vista and in Windows Server 2008, EFS uses the AES algorithm with 256-bit keys. If you enable this setting, AES-256 will be used.
FIPS local policy does not affect password key encryption.

The title of that reference and later content say
"In Windows XP and in later versions of Windows"

The "Applies To" section (at bottom) lists Win 7.  

This certainly suggests that what is said about Win Vista and Server 2008, etc. applies to Win 7.

Did you read http://technet.microsoft.com/en-us/library/cc750357.aspx  ?
If you click, for example, Procurement Officer under Audience it says
"Windows Vista, Windows Server 2008, or later in several places

The information in http:#a39260384 and http:#a39260669  are factual answers and certainly answer the question asked.

From the basic – what is it:

to  WHAT’S new in W7

 By default, EFS uses the 2,048-bit key size for self-signed RSA certificates and the 256-bit key for ECC certificates.
