Microsoft slashes IE support, sets 'huge' edict for Jan. 2016 | Computerworld
"In a surprise announcement yesterday, the head of IE's marketing said that after Jan. 12, 2016, Microsoft would support IE9 only on Windows Vista, IE10 only on Windows Server 2012,
and IE11 on Windows 7 and Windows 8.1.
IE7 and IE8 will drop off support completely, no matter what OS they run on.
The browsers will continue working, but Microsoft will halt technical support and stop serving security updates for the banned versions."

Last chance to upgrade IE or switch browsers as Microsoft's mandate looms | Computerworld

"Nearly 340 million people who run Microsoft's Internet Explorer have just a week to upgrade or switch browsers, or face a shutoff of the security patch spigot."

Support Ending for the .NET Framework 4.0, 4.5 and 4.5.1 on Tuesday

"In less than a week Microsoft will formally end support for versions 4.0, 4.5, and 4.5.1 of the .NET Framework. Users should upgrade to a later version such as the slightly incompatible .NET 4.5.2.

Before we move on, it should be noted that this only affects the 4.x series. The much older .NET 3.5 SP 1 will continue to be supported. In this context, support means having access to technical support, security updates, and hotfixes."
