I haven’t heard about x64 systems one way or the other.
Thanks. The article implies it’s only 32 bit but...? I’m not overly worried about this one.
x64 systems address the kernel in a way where this won’t affect them. I checked all of my x64 systems (2 at work and 2 at home), and none of them have these registry entries.
All of my 32-bit Windows OS had the registry entry, and I removed it.
The WOW stuff isn’t an explicit service. When you open a command line in Windows, the system drills down to the lowest common denominator for application execution—in this case 16 bit executions. Since most applications nowadays are written with x64 in mind, they don’t need to instantiate 16 bit compatibility mode, but since Microsoft is intent on backwards compatibility into the Stone Age, they left open this gaping hole.
