Re: Windows 10 who cares?
Also often the main cause of infection isn't necessarily Windows. More often it's user ignorance and other software creating other vulnerabilities (Java etc.).
Bit like criticising a car for having doors after the owner willingly opened it and let a nutjob get in.
It's a pretty tough job making millions of lines of code water-tight and idiot proof.
Personally I would prefer my OS to have a full custom install option that lets me cherry pick the bits I really need and leave out the stuff I never use. IMO having stuff installed I never use is just another avenue for attack.
