 My reading of https://blogs.technet.microsoft.com/srd/2013/12/11/software-
 defense-mitigating-common-exploitation-techniques/ is that this technique
 is used by default in Windows 8+ if you turn on ASLR. So adding the code
 manually would improve the situation on Windows 7; but would probably just
 eat memory (although this may not be a real problem) on anything above
 that.
