Windows Update error 0x80092004 Windows 7 & 2008

Microsoft changed the signing of update packages for Windows 7 and Windows Server 2008 R2 devices on the August 2019 Patch Day for the first time. The company signs packages only with SHA-2 since August 2019; it signed them with SHA-1 and SHA-2 previously but decided to drop SHA-1 because of known weaknesses.

Two updates need to be installed on Windows 7 and Windows Server 2008 R2 systems so that SHA-2 signed updates are installed correctly:

  • KB4474419 — SHA-2 code signing support update for Windows Server 2008 R2, Windows 7, and Windows Server 2008: August 13, 2019
  • KB4490628 — Servicing stack update for Windows 7 SP1 and Windows Server 2008 R2 SP1: March 12, 2019
