What is the Windows KB4474419 update?
Stand Alone security update KB4474419 released to introduce SHA-2 code signing support to Windows 7, Windows Vista, Windows Server 2008, and Windows Server 2008 R2. These older systems originally used SHA-1 for code signing. However, since Microsoft stopped the issuance of SHA-1 code signing in 2019, newly developed drivers can only be signed with SHA-2. KB4474419 was released to address this compatibility problem, enabling these older systems to utilize modern drivers.
