Back in November 2013 a whole giggle-gaggle of you were extremely interested in owning the entire TechNet library for Windows Server 2012 and Windows Server 2012 R2. As I stated then, Microsoft took the entire TechNet library for Windows Server 2012 and compiled it into a monstrous PDF containing around 8,000 pages of documentation.

Microsoft has now updated the PDF based on updates against the actual TechNet library documentation. The PDF, originally around 116MB, now sits proudly at almost 126MB. If you're like me, and have to have the latest and most up-to-date everything, you can grab the new release here:
