   you're talking about meltdown and/or spectre;   
      
   just a primitive question:   
      
   as you just mentioned that there will be patches for Windows, Linux, ...   
   so it is assumed the problem doesn't exist on patched systems;   
      
   but: isn't this a problem of these operating systems itself?   
      
   or in other words, I found a programme   
   https://github.com/ionescu007/SpecuCheck   
   which gives informations if the problem exists or not;   
      
   but what does it say, when it has requirements, the OS hasn't - e.g. on   
   old OS like Windows XP?   
      
   I can't compile it for WinXP ...   
      
   Thanks,   
   Walter
