Rudolph : Its a 3rd party application. Windows is an operating system. For obvious reasons you can't merge the two.

As far as I can work out it needs to prevent executables from running under the following path:

%AppData%\*.exe

Plus various other paths listed in the article below.

If Microsoft chose to implement the same method to prevent infection the problem is is that there are actually some legitimate applications that might run an executable file from that location and it would require the user to have the knowledge needed to add specific applications to an exclusion list. That's too complicated for many people to understand.

Steps needed to prevent infection:

Cryptolocker: How to avoid getting infected and what to do if you are - Computerworld

As you can see - any unsigned executable needs to be blocked as Cryptolocker file names are randomly generated.
