How To: Enable Defrag on Server 2008R2 and Windows 7 Using ConfigMgr Setttings Management

We found several systems recently where defrag was not enabled. Thanks to a little help from the TechNet forums, I was able to create a Compliance Settings Rule using PowerShell. Create a new compliance settings configuration item as follows:

1. Choose a name (Such as Enable Defrag).
2. Choose the supported platforms (all Windows 7, all Server 2008 R2)
3. Create a new Setting, choose Script for the setting type, and Boolean for the data type.
4. Paste the PowerShell code below for the Discovery Script:

   # Used by the RegisterTaskDefinition method
   $TASK_CREATE_OR_UPDATE = 0x6
   
   # Specify the computer name
   $computerName = "localhost"
   # Specify the task's name
   $taskName = "\Microsoft\Windows\Defrag\ScheduledDefrag"
   
   $taskService = new-object -comobject "Schedule.Service"
   $taskService.Connect($computerName)
   $taskFolder = $taskService.GetFolder("\")
   $registeredTask = $taskFolder.GetTask($taskName)
   $registeredTask.Enabled = $TRUE
   $taskDefinition = $registeredTask.Definition
   $taskDefinition.Triggers | % {$_.Enabled}
   

5. Paste the PowerShell code below for the Remediation Script.

   $TASK_CREATE_OR_UPDATE = 0x6
   
   # Specify the computer name
   $computerName = "localhost"
   # Specify the task's name
   $taskName = "\Microsoft\Windows\Defrag\ScheduledDefrag"
   
   $taskService = new-object -comobject "Schedule.Service"
   $taskService.Connect($computerName)
   $taskFolder = $taskService.GetFolder("\")
   $registeredTask = $taskFolder.GetTask($taskName)
   $registeredTask.Enabled = $TRUE
   $taskDefinition = $registeredTask.Definition
   $taskDefinition.Triggers | foreach-object { $_.Enabled = $TRUE }
   [Void] $taskFolder.RegisterTaskDefinition($taskName, $taskDefinition,
    $TASK_CREATE_OR_UPDATE, $NULL, $NULL, $taskDefinition.Principal.LogonType)
   

6. Create a new Compliance Rule tab of the configuration item, where Enabled = True, as shown next:
7. Add this configuration item to a baseline and deploy to a collection. Note that in order to  execute Compliance Management scripts that use Powershell, you may need to modify the client setting named “PowerShell Execution Policy”  to Bypass.
