Windows 7 Users: You Need SHA-2 Support or No Windows Updates After July 2019 (zdnet.com)

Windows 7 and Windows Server 2008 users need to have SHA-2 code-signing installed by July 16, 2019, in order to continue to get Windows updates after that date. Microsoft issued that warning on February 15 via a Support article. From a report: Windows operating system updates are dual-signed using both the SHA-1 and SHA-2 hash algorithms to prove authenticity. But going forward, due to "weaknesses" in SHA-1, Microsoft officials have said previously that Windows updates will be using the more secure SHA-2 algorithm exclusively. Customers running Windows 7 SP1, Windows Server 2008 R2 SP1 and Windows Server 2008 SP2 must have SHA-2 code-signing support installed by July 2019, Microsoft officials have said.
