WSUS – Failed Computers (Display.ps1)

Generate a CSV of client machines that had Windows Update installation errors over a recent time window, by querying WSUS event history (errors only). Faster and more accurate than stitching multiple daily exports. If the UpdateServices module isn’t present, the script uses the WSUS Admin .NET DLL directly.

Requirements

• Run on the WSUS server, in an elevated 64-bit Windows PowerShell (5.1).
• WSUS PowerShell module UpdateServices (installed with WSUS/RSAT) or the Admin DLL: C:\Program Files\Update Services\Tools\Microsoft.UpdateServices.Administration.dll
• Local access to WSUS (HTTP 8530 or HTTPS 8531).
