The "How to migrate SBS 2011 to Windows Server 2019 Standard, Datacenter or Essentials" tutorial shows how to remove the Client Agent software in Chapter 6. The example shows the ClientAgent as the only 2011-related software, but in my environment I also found "Windows Small Business Server 2011 Standard WMI Provider" on my Windows 10 desktops.
Should I follow the same steps and use the powershell command:
Get-wmiobject win32_product | ?{$_.name -match "Windows Small Business Server 2011 Standard WMI Provider"} | %{$_.uninstall()}
to remove it?
Sure, modify that command and remove the WMI provider also.
