I have been using the [Powershell Scheduled Task Cmdlets](http://technet.microsoft.com/en-us/library/jj649816.aspx) to create a scheduled task on our servers. 

How do I elect to &#39;Run whether a user is logged in or not using this API?

I&#39;ve created `action`, `trigger`, `principal` and `settings` objects, and passed them to `Register-ScheduledTask`, as below:

    $action = New-ScheduledTaskAction -Execute foo.exe -Argument &quot;bar baz&quot;
    $trigger = New-ScheduledTaskTrigger -Once -At $startTime -RepetitionInterval (New-TimeSpan -Minutes 1) -RepetitionDuration ([Timespan]::MaxValue)
    $principal = New-ScheduledTaskPrincipal -UserId &quot;$($env:USERDOMAIN)\$($env:USERNAME)&quot; -LogonType ServiceAccount
    $settings = New-ScheduledTaskSettingsSet -MultipleInstances Parallel

    Register-ScheduledTask -TaskName $taskName -TaskPath &quot;\my\path&quot; -Action $action -Trigger $trigger -Settings $settings -Principal $principal

When I create a scheduled task like this, it defaults to &#39;Run only when the user is logged on.

[This question](https://stackoverflow.com/questions/12770293/how-to-set-schedule-service-run-whether-user-is-logged-on-or-not-in-powershell) shows how to do so using COM objects, and [this one](https://stackoverflow.com/questions/11190405/how-to-schedule-a-task-wether-the-user-is-logged-on-or-not-in-powershell) using schtasks.exe, but how do I do it using the `*-ScheduledTask*` cmdlets?


Powershell: Set a Scheduled Task to run when user isn&#39;t logged in

I am searching for a simple command to see logged on users on server.
I know this one :

    Get-WmiObject -Class win32_computersystem

but this will not provide me the info I need.
It returns :
domain
Manufactureer
Model
Name (Machine name)
PrimaryOwnerName
TotalPhysicalMemory

I run Powershell 3.0 on a Windows 2012 server.

Also 

    Get-WmiObject Win32_LoggedOnUser -ComputerName $Computer | Select Antecedent -Unique

gives me not the exact answers I need.
I would love to see as well the idle time, or if they are active or away.

Given a standard json string value:

    $jsonString = &#39;{ &quot;baz&quot;: &quot;quuz&quot;, &quot;cow&quot;: [ &quot;moo&quot;, &quot;cud&quot; ], &quot;foo&quot;: &quot;bar&quot; }&#39;

How can I get this to be all pretty with newlines, preferably without brute-force regex?

Simplest method I&#39;ve found so far is:

    $jsonString | ConvertFrom-Json | ConvertTo-Json 

However, that seems kinda silly. 

Prettify json in powershell 3

I&#39;m trying to create a JSON-serialized array. When that array contains only one item I get a string, not an array of strings (in JSON).

Multiple Items (works as expected):

    [
        &quot;one&quot;,

Single Item Array (not as expected):

Am I missing something?

How do I update JSON file using PowerShell

Can anybody explain the details? If I create an object using

    $var = [PSObject]@{a=1;b=2;c=3}

and then I look for its type using `getType()` PowerShell tells me it&#39;s of type **Hashtable**.

When using [Get-Member][1] (alias `gm`) to inspect the object it&#39;s obvious that a hashtable has been created, since it has a `keys` and a `values` property. So what&#39;s the difference to a &quot;normal&quot; hashtable?

Also, what&#39;s the advantage of using a PSCustomObject? When creating one using something like this

    $var = [PSCustomObject]@{a=1;b=2;c=3}

the only visible difference to me is the different datatype of **PSCustomObject**. Also instead of keys and value properties, a inspection with `gm` shows that now every key has been added as a NoteProperty object.

But what advantages do I have? I&#39;m able to access my values by using its keys, just like in the hashtable. I can store more than simple key-value pairs (key-object pairs for example) in the PSCustomObject, JUST as in the hashtable. So what&#39;s the advantage? Are there any important differences?

Difference between PSObject, Hashtable, and PSCustomObject

I have a type `FooObject` and I have a JSON file which was serialized from a `FooObject` instance. Now I want to use `ConvertFrom-Json` to load the JSON file to memory and covert the output of the command to a `FooObject` object, and then use the new object in a cmdlet `Set-Bar` which only accept `FooObject` as the parameter type.

But I notice that the output type of `ConvertFrom-Json` is `PSCustomObject` and I did not find any way to convert `PSCustomObject` to `FooObject`.

I&#39;m having trouble with this command:

    gc .\domains.txt | Get-ADDomain

As the name implies, domains.txt contains a list of Active Directory to query (all domains are in the same forest).

If I run it on my Windows 8 machine everything works fine and I get the expected results, instead on a Windows 2008 R2 SP1 member server (not a DC) with WMF 3.0 I get result only from the first domain in the list and for the others:

    Get-ADDomain : A referral was returned from the server


If I query a domain in the list with:

    Get-ADDomain &lt;Domain name here&gt;

it works fine.

Powershell v3.0 pipe issue

I am searching for a list of all colors I can use in PowerShell. Since we need to provide names and no hexnumbers, it&#39;s hard to figure out if a color exists or not, at least if you don&#39;t know how :))

For example, as `-foregroundcolor`

    write-host &quot;hello world&quot; -foregroundcolor &quot;red&quot;

The following PowerShell code

    #Get a server object which corresponds to the default instance
    $srv = New-Object -TypeName Microsoft.SqlServer.Management.SMO.Server

How can you test if an object has a specific property?

Appreciate I can do ...

    $members = Get-Member -InputObject $myobject 

and then `foreach` through the `$members`, but is there a function to test if the object has a specific property?

**Additional Info:** 
The issue is I&#39;m importing two different sorts of CSV file, one with two columns, the other with three. I couldn&#39;t get the check to work with &quot;Property&quot;, only with &quot;NoteProperty&quot; ... *whatever the difference is*

    if ( ($member.MemberType -eq &quot;NoteProperty&quot; ) -and ($member.Name -eq $propertyName) )

The OS that I am using is Windows 7, and the PowerShell version that is installed here is 2.0. Is it possible for me to upgrade it to version 3.0 or 4.0?

Because there are cmdlets that version 2.0 can&#39;t recognize.



How to upgrade PowerShell version from 2.0 to 3.0

I use Powershell&#39;s `Invoke-WebRequest` method to download a file from Amazon S3 to my Windows EC2 instance.

If I download the file using Chrome, I am able to download a 200 MB file in 5 seconds.  The same download in PowerShell using `Invoke-WebRequest` takes up to 5 minutes.  

Why is using `Invoke-WebRequest` slower and is there a way to download at full speed in a PowerShell script?

Powershell - Why is Using Invoke-WebRequest Much Slower Than a Browser Download?

Consider JSON in this format :

    &quot;Stuffs&quot;: [
        {
            &quot;Name&quot;: &quot;Darts&quot;,
            &quot;Type&quot;: &quot;Fun Stuff&quot;
        },
        {
            &quot;Name&quot;: &quot;Clean Toilet&quot;,
            &quot;Type&quot;: &quot;Boring Stuff&quot;
        }
    ]

In PowerShell 3, we can obtain a list of Stuffs :

    $JSON = Get-Content $jsonConfigFile | Out-String | ConvertFrom-Json

Assuming we don&#39;t know the exact contents of the list, including the ordering of the objects, how can we retrieve the object(s) with a specific value for the Name field ? 

Brute force, we could iterate through the list : 

    foreach( $Stuff in $JSON.Stuffs ) { 

But I am hopeful there exists a more direct mechanism ( similar to Lync or Lambda expressions in C# ).

How can I hide the progress display of `Invoke-WebRequest`? I do a lot of successive requests and have my own `Write-Progress` display that I use, so I don&#39;t need the built-in one popping up underneath it every time.

I use the mshtml results (the IE COM object) that are created from the result of `Invoke-WebRequest` automatically, so I can&#39;t switch to a `WebClient` or something like that, unless someone provides instructions on how to get an mshtml object from a WebClient request.
