Data Execution Prevention

[img_assist|fid=49|thumb=1|alt=Windows PIC]Found a very good description of Data Execution Prevention that's enabled in SP2+ versions of Windows XP. I recently got my hands on an AMD 64 and this is the enhancement that I noticed first. I have no clue though how useful this is. Note that Data Execution Prevention (System -> Advanced -> Performance Settings -> Data Execution Prevention) is on only for Windows services by default. Try turning it on for all programs. YMMV.
