Examples on how SMB1 can be removed

Remove-SMB1.ps1

# Suggestion 1: Define in PowerShell DSC configurations for target systems that SMB 1 should be absent
configuration HyperV {

Import-DscResource -ModuleName PSDesiredStateConfiguration

node localhost {

    WindowsFeature SMB1 {

      Ensure = 'Absent'
      Name = 'FS-SMB1'

    }
  
  }

}

# Suggestion 2: Uninstall SMB 1 from base images so that new machines is not created with SMB 1 enabled. This is an example on how to do it using offline servicing.
Uninstall-WindowsFeature -Vhd 'D:\VM Templates\WS2016Base.vhdx' -Name FS-SMB1 -Remove

# Suggestion 3: Identify target systems you can safely remove SMB 1 from. 
# The below example is targeting Hyper-V hosts, which you can safely remove SMB 1 from.

# Get all Hyper-V servers from System Center Virtual Machine Manager (Nano Server is being excluded since SMB 1 is already absent)
Import-Module -Name VirtualMachineManager

$HyperVHosts = Get-SCVMHost | Select-Object -Property *,@{name='VMMAgentVersion';e={$_.Agent.AgentVersion.ToString()}} | Where-Object {
  $_.VirtualizationPlatform -eq 'HyperV' -and
  $_.VMMAgentVersion -NotLike "10.*" -and
  $_.CommunicationStateString -eq 'Responding'
}  | Sort-Object Name

$SMB1StatusBefore = Invoke-Command -ComputerName $HyperVHosts.Name -ScriptBlock {Get-WindowsFeature -Name FS-SMB1} | Select-Object Name,Installed,PSComputerName

$Removal = Invoke-Command -ComputerName $HyperVHosts.Name -ScriptBlock {
  
      if ((Get-WindowsFeature -Name FS-SMB1).Installed) {
  
          Uninstall-WindowsFeature -Name FS-SMB1
  
      }
  
  }

$SMB1StatusAfter = Invoke-Command -ComputerName $HyperVHosts.Name -ScriptBlock {Get-WindowsFeature -Name FS-SMB1} | Select-Object Name,Installed,PSComputerName

# Inspect changes
Compare-Object -ReferenceObject $SMB1StatusBefore -DifferenceObject $SMB1StatusAfter -Property Installed -IncludeEqual

# Do note that a reboot is required after uninstalling SMB 1 from a running system
