Is the first post in this forum not clear? The patched file does not get "installed" but rather overwrites the existing file in MNYCoreFiles.
I just revisited
http://blogs.msdn.com/b/oldnewthing/archive/2012/11/13/10367904.aspx It has a note that says "Update: An official fix for this issue has been released to Windows Update, although I must say that I think my patch has more style than
the official one. You do not need to patch your binary. Just keep your copy of Windows 8 up to date and you'll be fine. "
That seems to imply that if you are using Windows 8, that the swap gets done for you. I expect there is more to the story.
