Home windows 7 and Server 2008 Updates to Require SHA-2 Help Beginning July – BleepingComputer

Microsoft introduced on its help web site that future Home windows 7 and Home windows Server 2008 updates would require SHA-2 code signing help to be put in beginning with July 16, 2019.

SHA-2 code signing help can be added to Home windows 7 SP1 and Home windows Server 2008 R2 SP1 on March 12 and April 9 respectively, as a part of devoted standalone safety updates.

Whereas Home windows updates are at the moment utilizing each the SHA-1 and SHA-2 hash algorithms for codesigning functions, migration to the SHA-2 is important due to the SHA-1 algorithm changing into impacted by numerous weaknesses that made it much less safe through the years.

In accordance with Microsoft’s help article:

To guard your safety, Home windows working system updates are dual-signed utilizing each the SHA-1 and SHA-2 hash algorithms to authenticate that updates come instantly from Microsoft and weren’t tampered with throughout supply. Attributable to weaknesses within the SHA-1 algorithm and to align to business requirements Microsoft will solely signal Home windows updates utilizing the safer SHA-2 algorithm solely.

Microsoft additionally advises prospects who use Home windows Server Replace Companies (WSUS) 3.zero SP2 to replace their servers with the SHA2 updates for WSUS 3.zero SP2 till June 18 to guarantee that they will ship future SHA2-signed updates to their enterprise surroundings.

Home windows Server Replace Companies (which was beforehand often called Software program Replace Companies) is a program designed to permit Home windows directors to handle replace and hotfix distribution to stations in a company surroundings.

The total schedule for the SHA-2 code signing help migration course of will be discovered within the desk beneath, nonetheless the dates are topics to vary based on Microsoft:
