Set Corporate Wallpaper with Intune for Non Windows 10 Enterprise or Windows 10 Education Machines

July 30, 2019 Brad Wyatt Comments 0 Comment

By default, there is an Intune device configuration property that can set a devices wallpaper (Profile Type: Device Restrictions > Personalization) BUT this is only applicable on devices running Windows 10 Enterprise and Windows 10 Education. Luckily, using PowerShell we can download a image from the web, save it locally, and set it as our users wallpapers.

First we need to create our PowerShell script. In PowerShell ISE I created the following script and saved it to my local machine

$RegKeyPath = "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\PersonalizationCSP"


$DesktopPath = "DesktopImagePath"
$DesktopStatus = "DesktopImageStatus"
$DesktopUrl = "DesktopImageUrl"

$StatusValue = "1"


$url = "https://www.thelazyadministrator.com/wp-content/uploads/2019/07/nicewall.jpg"
$DesktopImageValue = "C:\MDM\wallpaper_LazyAdmin.jpg"
$directory = "C:\MDM\"


If ((Test-Path -Path $directory) -eq $false)
{
	New-Item -Path $directory -ItemType directory
}

$wc = New-Object System.Net.WebClient
$wc.DownloadFile($url, $DesktopImageValue)



if (!(Test-Path $RegKeyPath))
{
	Write-Host "Creating registry path $($RegKeyPath)."
	New-Item -Path $RegKeyPath -Force | Out-Null
}


New-ItemProperty -Path $RegKeyPath -Name $DesktopStatus -Value $StatusValue -PropertyType DWORD -Force

Connect and Navigate the Microsoft Graph API with PowerShell

July 22, 2019 Brad Wyatt Comments 20 comments

Graph is Microsoft’s RESTful API that allows you to interface directly with Azure AD, Office 365, Intune, SharePoint, Teams, OneNote, and a whole lot more. By using the Invoke-RestMethod PowerShell cmdlet we can connect and interact directly with the Graph API. The Invoke-RestMethod cmdlet sends HTTP and HTTPS requests to Representational State Transfer (REST) web services that returns richly structured data. PowerShell formats the response based on the data type. For an RSS or ATOM feed, PowerShell returns the Item or Entry XML nodes. For JavaScript Object Notation (JSON) or XML, PowerShell converts (or deserializes) the content into objects.¹In this article, I will walk you through setting up the Azure Application, assigning proper permissions, Authentication and finally running queries against the Graph API. Once you understand how to properly authenticate and format queries you will see how powerful Graph can be for you and your organization.
