You have no out-of-the-box solution for this, other than *EFS
(*E*ncrypting *F*ile *S*ystem) feature of Windows 2000+ NTFS, or fo
Vista Business/Enterprise/Ultimate the *BitLocker* tool (you need th
TPM compliant BIOS).
However, if you need just to protect your favourite pR0N like I do fro
the prying eyes, there is one excellent solution called TrueCrypt
confirmed to work on all modern Windows architectures, it can be foun
here: 'TrueCrypt - Free Open-Source On-The-Fly Disk Encryption Softwar
for Windows Vista/XP, Mac OS X and Linux' (
