Symptoms

After you install a Microsoft Exchange Server 2019 security update (SU) or hotfix update (HU), you experience issues and decide to uninstall the update. However, when you try to do this through the Control Panel by using the Add/Remove Programs feature, Windows redirects you to the Windows Server 2025 Settings menu. After the redirection, you can’t uninstall the update because the update doesn’t appear on the Settings menu.

Workaround

To start the process to uninstall the latest Exchange Server 2019 SU or HU on a Windows Server 2025-based server, run the following command at an elevated PowerShell window:

Start-Process "msiexec.exe" -ArgumentList ((Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Patch").UninstallString -replace "^msiexec\s+", "")
