Windows 10 Windows 2012 R2 Standard - MS12-073: Vulnerabilities in Microsoft IIS

Hi,

I'm using Windows Server 2012 R2 Standard, and I have "MS12-073: Vulnerabilities in Microsoft IIS Could Allow Information Disclosure" vulnerability in my production server. When I search the internet for this, all I can see is that this is the issue for Vista, 2008, 7, and 2008 R2 , not 2012. How then do I go on about fixing this when I'm using Windows 2012 R2 Standard ?
