Of lesser interest to many is the official "End of Life_ for Windows Vista.
Also of note is the security guidance, Defense-in-Depth Update for Microsoft Office:
"Microsoft has released an update for Microsoft Office that turns off, by default, the Encapsulated PostScript (EPS) Filter in Office as a defense-in-depth measure. Microsoft is aware of limited targeted attacks that could leverage an unpatched vulnerability in the EPS filter and is taking this action to help reduce customer risk until the security update is released.
Microsoft strongly recommends against turning on the EPS filter at this time, however customers who need to turn on the EPS filter can reference KB Article 2479871."
