  2. Enable TPM security using the following command:
    Get-CimInstance -Namespace root\dcim\sysman -ClassName DCIM_BIOSService | Invoke-CimMethod -MethodName SetBIOSAttributes -Arguments @{AttributeName=@("Trusted Platform Module ");AttributeValue=@("1");AuthorizationToken="<Admin password>"}
  3. Restart the system.
