What can we learn as a person today?
Have you ever come across the K.I.S.S. principle? It stands for “Keep It Simple, Stupid,” and was made up by Kelly Johnson of Lockheed Skunk Works. The idea behind it is that keeping things simple often leads to the best results. In addition to being useful in engineering, this piece of advice can also be used to clear out our daily lives and the places we live in. In a world that’s always looking for new and difficult things, getting back to the basics has a lot of power.
Imagine applying K.I.S.S. to every part of your life, like picking tasks, responsibilities, and even your social media interactions, with a focus on how simple they are. What if we focused on the things that really make life better, make us happy, or are absolutely necessary? We don’t need to do less; we just need to be more thoughtful about how we spend our time and energy. Cutting through the noise isn’t about making things easier; it’s about making things clearer and better.
When you use K.I.S.S., it’s like deciding to juggle fewer balls more skillfully instead of more balls that you might drop. To breathe, focus, and do well, you need to make space for that. It’s easier to grow, be creative, and find peace when you have fewer responsibilities to choose. It’s not only smart to keep things simple, it’s also a way to live a more focused and satisfying life.
Over the years of Intune deployments, I have searched for a way to let my end users know that an application is being installed or uninstalled from their computer. I have used things ranging from notification bubbles to blanking a screen. All of these methodologies are poor at best. I found a few paid items that companies just didn’t want to pay for due to the insanity of the pricing. For example, one company wanted us to pay 150 USD per deployment. Times that by 1500 devices, that adds up quickly. It wasn’t until I found the PowerShell App Deployment Toolkit that I found what I was finally looking for.
What is the PowerShell App Deployment Toolkit?
This toolkit is an immensely powerful and amazingly simple setup. You can download the tool kit here. It provides a framework to install and uninstall applications using PowerShell through a signed application. This allows us to deploy complex and confusing deployments as a single package. A good example would be AutoCAD. Recently, I was tasked with standardizing AutoCAD in a single department. Some members used AutoCAD 2016, some used 2024. This was a problem as the 2024 files did not work with the 2016 AutoCAD. Thus, I needed to uninstall the previous versions of AutoCAD before I installed the current version. As all files are backed up, I didn’t have to worry about them losing any files. The toolkit was perfect for this.
Key items I like of the toolkit
Simple packaging
Many application toolkits come with complex packaging. It’s normally an application that wraps itself around another application that keeps doing this until it’s all transparent. With the PowerShell App Deployment Toolkit, all you need to interact with is the deploy-application.ps1 file. That’s assuming you are doing more than an a MSI file. If you are only using an MSI file, all you need to do is drop the file in.
As you can see in the screen shot, this is the package. When you download the zip file, you will be greeted with this amazing structure. The Deploy-Application.ps1 is where our code will go. The Files folder is where the installer files would go. Following our auto cad example, the installer and updates would all be placed inside the Files folder.
Deploy-Application.ps1
This file has an amazing setup. It first has a wall of documentation inside the file itself. The file explains each step along the way. It is broken up into installation, uninstallation, and repair. Each section has a Pre, during and post process in each section. This is great if you need to kill some services, send a message or more. It’s also helpful because it gives you a structure to work within.
The Commands
Inside this packaging there are many useful commands. As I stated in the intro, it’s full of ways to communicate what you are doing with the end user. During an application install, you can show which applications needs to be turned off for the install to work by using the show-installationwelcome command.
This example shows us it wants to close the applications and gives the user a 60 second window to do so. This isn’t the only thing this command can do.
Other commands like execute-process, will launch processes that you need from the file directory and more. All while logging what’s going on. You can find a full help system for all the unique commands inside the tool kit. Navigate to the tool kit > AppDeployToolkit > AppDeployToolkithelp.ps1 will bring up a gui that allows you to read all about the commands.
Using the Toolkit with Intune
If you want the tool kit to work with the end user profile, then you will need to grab a unique little tool from MDT. We will need the ServiceUI.exe from the MDT software. You can download MDT here. Once you have the MDT installed. we need to pull the ServiceUI.exe out of the MDT install. Navigate to, C:\Program Files\Microsoft Deployment Toolkit\Templates\Distribution\Tools\x64 and copy the ServiceUI.exe file. Place this file in the home of your PowerShell App Deployment Toolkit file structure.
As you can see, the ServiceUI.exe is in the root folder. Now we need to create the package. We can create a win32 app package. I covered this here. This is the same concept.
The folder would be the folder with your toolkit
The setup file would be the Deploy-Application.exe
The output file would be wherever you want the Intune app to be dumped.
and we don’t need to catalog the folder.
Once you have your application built, it’s time to see how it works inside Intune. We start by building your application package. As stated in the previous blog, we start the application by uploading. The big difference here is our install and uninstall commands.
Understanding the commands
Our install command will be the using the ServiceUI.exe and the deploy-application.exe
By default, the Deploy-application.exe will be interactive. There are two flags for the Deploy-Application and here are what they are.
DeploymentType: (Super Straight forward)
Install: Installs the application
Uninstall: Uninstalls the application
Repair: repairs the application.
DeployMode:
Interactive: Shows all of the prompts needed.
NonInteractive: Only shows the required prompts.
Silent: Shows no prompts.
We can translate the command above by using these flags. By default the Deploy-application.exe is install and interactive. So, we know that the application would be prompted and the end user will see the command. The uninstall command will uninstall and it will be interactive. The ServiceUI.exe allows you to run applications as the user in and the system at the same time. The biggest issue with the ServiceUI.exe is the application will not install until someone logs in. No flags are needed here.
Over all, PSappdeploytoolkit changes the ball game with deployments. I encourage anyone and everyone to dig deeper into it.
What can we learn as a person today?
I live in the south of United states. From time to time I will hear people battling over belief systems. In my life time I have come to an understanding of how these systems work. I liken “objective truth” as fish in a sea. Our belief systems is the net we use to capture those fish. Some nets are better than others. The water of the sea is useless, distracting, or misinformation. It only makes it harder to bring those pieces of the objective truth into ourselves. A good net can capture a lot of fish, and let the water out at the same time. A bad net, like a tarp, captures some but becomes unmanageable due to the water. This is the same way with our beliefs. We are only strong enough to lift so much at different points in our lives.
Premade Nets
I see organized religions as premade nets. Think of it like a tool kit. It’s a format that is easy to use and allows you to do stuff with it. Does the toolkit work for everyone, no. Just like this PowerShell toolkit, it would be useless in a world without powershell. So chromeOS, this toolkit isn’t useful. This is the same with some beliefs. They are useful where they are, but not useful in other places. Sometimes these toolkits/nets, are useful for some but not others. If you don’t know PowerShell, this toolkit wouldn’t be useful to you. If you are shame sensitive, some religions are not for you.
Everyone has their own tool set or net. No single tool set is inherently bad. It’s how we use them and where we use them. If you take a net to a small pond, get ready to waste your time and damage your net. If you throw your net aggressively into a aggressive sea, get ready to lose that net.
Homemade Nets
Once someone understands how the nets are made and how to repair them, It’s always best for them to start building their own nets using the techniques they have used on their previous nets. By having a net/toolset of your own, this allows you to have full knowledge and be able to repair quickly. This belief system would be uniquely yours and different from others. So, when it breaks, you can grow it, replace parts, and more without having any problems. It’s yours and no one elses.
This past month I was given a task to Uninstall a few applications in Intune. However, the app’s uninstall feature did not work according to plan. However, a bunch of these worked with the cim methods of uninstall. Which I thought was funny. After writing a bunch of the same code over and over again, I decided to write a General Uninstaller for Intune. This also requires a custom Detection Script.
Here we have a general uninstaller for Intune. This script allows us to feed the product name as is or we can add wild cards to the name. We start off the script by grabbing the product names from the user. This will be done during the intune setup. When it deploys, the first thing this script does is grab all the applications inside the win32_product. If the application didn’t register in this windows system, then this script is going to be pointless for you.
Once we have the products, we go through each Product Name. We first check to see if the product is on the system. If it isn’t, we output success and exit with a unique exit code. This will be used later. However, if the product is on the machine, we grab the install location. Then we pipe the product into the uninstall method in the cim method command. Finally, we see if the install location exists inside the installed object. Some applications give us this information some don’t. Some give us multiple locations while others don’t.
To work around this, we check if install location property is null. If it isn’t null, then we move on and start a loop. The loop is only because some install locations have more than one location. Then we test if the file path still exists. Sometimes, the applications uninstaller will remove the folder, sometimes, it doesn’t and that’s why we test. If the file location is there still, we remove it with a good old force and recurse. Finally, we exit with the unique exit code.
With any custom script installs or uninstalls, a custom detection script is necessary. The first step is to grab the product names. Just like before, it’s a list of strings. So they can do more than one. Then we grab all the products with our cim instance and win32_product. Then we loop through each product name and see if the product exists still. If it does, we exit with a 1. This basically says, I failed! Intune needs a string and an exit code of 0 to be successful. The exit of 1 without the string ends the script and without that string, intune assumes failure. However, if we go through them all, and none trigger the exit, then we are safe to exit with a 0 and the beautiful word success.
Building it out in Intune.
Building the IntuneWin File
The first thing you will need to do is save your script into a folder and then download the WinIntuneApp, aka, Win32 Prep Tool, to package up the powershell script. Unpackage this tool and start up your command prompt. The application will guide you through the process of setting up a intunewin app.
General Uninstaller for Intune
Please specify the source folder: This is the folder that will have your script inside of it. If you wanted to create something more complex, this part would change your way of deployment. Future blog post coming.
Please Specify the setup file: This is going to be the powershell name. General-Uninstall.ps1
please specify the output folder: This is the folder that the intunewin file will be dropped.
Do you want to specify catalog folder (Y/N)? This one is for more advanced packages. We can say no to this option for this setup.
Setting Up Intune for Your Uninstaller
Now we have the IntuneWin file. It’s time to setup the intune Deployment. This is where you will be able to add things like the productname to our General Uninstaller for Intune.
Navigate to Endpoint Manager
Click Apps
Click Windows
Click Add
Click the Select App Package File.
Add the General-Uninstall.IntuneWin file.
Click ok
Change the Name
Click the edit Description and add a detailed description for other users. Make sure to provide instructions on what to do with the detection script.
The publisher can be your company or in my case self.
The gategory is going to be computer management as it is a general uninstaller.
Feel free to add any additional information. Link this blog post if you wish for the information URL.
The Uninstall command can be as simple as a removal file.
Device Restart Behavior: Determine behavior based on return codes
Return Codes: Remember that unique exit code we had in the script. This is where you would place that code. I have it as 1212 is a success.
The next screen the requirement screen. We can do a lot with this screen, but we don’t need to here.
Operating System Architecture:
32
64
Minimum Operating System: Windows 10 1607.
Now we need to setup the custom detection.
Select User A custom Detection Script
Validate your product names to be uninstalled.
Upload and click next.
Accept the defaults for Dependencies and Supersedences.
The final screen is where you are able to assign the script to people. There are three sections. Required, aviable for enrolled devices and uninstall. This is where you will select who is going to get what.
Testing, Monitoring, and deployment
The assignment area is where you assign the script to who you want. This is very important. Here is where you would want to test the users. Have a test group and apply it first. H
Deploy the uninstall app to the test device group.
Monitor the Intune deployment status for the app to ensure successful deployment to devices/users.
Test if the application is still on a target computer. This can be done with control pannel, powershell, and more options.
Redefine and correct any issues and restart the testing.
Deploy
What can we learn as a person today?
When was the last time you threw a rock? How about a rock in a lakes? The last time you did, did you notice the ripples? Just like a deployment like this can cause ripples in your company, removing things from your life can cause just as many ripples in yourself. Make sure you are ready to let go of that thing you are holding onto. It’s always a good idea to test it out, or have a support group to help you. Those ripples can do some damage. So be ready to Uninstall parts of your life before you do it.
Recently I was working with a company that gave me a really locked down account. I wasn’t use to this as I have always had some level of read only access in each system. I was unable to create a graph API application either. So, I was limited to just my account. This was a great time to use the newer command lines for graph Api as when you connect to Graph API using the PowerShell module, you inherit the access your account has. So today we will Get Intune Devices with PowerShell and Graph API.
The Script
Function Get-IntuneComputer {
[cmdletbinding()]
param (
[string[]]$Username,
[switch]$Disconnect
)
begin {
#Connects to Graph API
#Installs the Module
if ($null -eq (Get-Module Microsoft.Graph.Intune)) {Install-module Microsoft.Graph.Intune}
#Imports module
Import-Module Microsoft.Graph.Intune
#Tests current Connection with a known computer
$test = Get-IntuneManagedDevice -Filter "deviceName eq 'AComputer'"
#If the test is empty, then we connect
if ($null -eq $test) {Connect-MSGraph}
}
process {
#Checks to see if the username flag was used
if ($PSBoundParameters.ContainsKey('Username')) {
#if it was used, then we go through each username get information
$ReturnInfo = foreach ($User in $Username) {
Get-IntuneManagedDevice -Filter "userPrincipalName eq '$User'" | select-object deviceName,lastSyncDateTime,manufacturer,model,isEncrypted,complianceState
}
} else {
#Grabs all of the devices and simple common information.
$ReturnInfo = Get-IntuneManagedDevice | Get-MSGraphAllPages | select-object deviceName,lastSyncDateTime,manufacturer,model,isEncrypted,complianceState,userDisplayName,userPrincipalName
}
}
end {
#Returns the information
$ReturnInfo
#Disconnects if we want it.
if ($Disconnect) {Disconnect-MgGraph}
}
}
The Breakdown
Parameters
We enter the script with the common parameters. Command let binding flag. This gives us additional parameters like verbose. Next, we have a list of strings called Username. We are using a list of strings to allow us to have multiple inputs. Doing this, we should be able to use a list of usernames and get their Intune Device information. Note that this is a multiple input parameter, thus, you will need to deal with it with a loop later. Next is the Disconnect switch. It’s either true or not. By default, this script will keep connected to Intune.
Connecting to Intune
Next we will connect to the Intune system. First, we need to check and install the module. We check the install by using the get-module command. We are looking for the Microsoft.Graph.Intune module. If it doesn’t exist, we want to install it.
if ($null -eq (Get-Module Microsoft.Graph.Intune)) {Install-module Microsoft.Graph.Intune}
If the module does exist, we will simply skip the install and move to the import. We will be using the importing the same module
Import-Module Microsoft.Graph.Intune
Afterwards, We want to test the connection to Microsoft Intune. The best way to do this is to test a command. You can do it however you want. I am testing against a device that is in Intune.
We will be using this command later. Notice the filter. We are filter the deviceName here. Replace the ‘AComputer’ with whatever you want. If you want to use another command, feel free. This was the fastest command that tested. The above command will produce a null response if you are not connect. Thus, we can test, $test with an if statement. If it comes back with information, we are good, but if it is null, we tell it to connect.
if ($null -eq $test) {Connect-MSGraph}
Get Intune Devices with PowerShell
Now it’s time to Get Intune Devices with PowerShell. The first thing we check to see is if we used a username parameter. We didn’t make this parameter mandatory to give the script flexibility. Now, we need to code for said flexibility. If the command contained the Username flag, we want to honor that usage. We do this with the PowerShell Bound Parameters. The PowerShell Bound Parameters is the – that come after the command. We are looking to see if it contains a key of username. If it does, we want to grab the needed information with the username. While if it doesn’t, we grab everything.
if ($PSBoundParameters.ContainsKey('Username')) {
#Grab based on username
} else {
#get every computer
}
As we spoke about the list of string parameter needing a loop, this is where we are going to do that. We first create a foreach loop of users for the username. Here, the we will dump the gathered information into a Return variable of $ReturnInfo. Inside our loop, we gather the requried information. The Get-IntuneManagedDevice command filter will need to use the userPrincipalName. These filters are string filters and not object filters. Thus, the term like will cause issues. This is why we are using the equal term.
Now, if we are not searching the Username, we want to grab all the devices on the network. This way if you run the command without any flags, you will get information. Here, we use the Get-IntuneManagedDevice followed by the Get-MSGraphAllPages to capture all the pages in question.
Now it’s time to end the script. We want to return the information gathered. I want to know some basic information. The commands presented produces a large amount of data. In this case we will be selecting the following:
Finally, we test to see if we wanted to disconnect. A simple if statement does this. If we choose to disconnect we run the Disconnect-MgGraph command.
if ($Disconnect) {Disconnect-MgGraph}
What can we learn as a person
In PowerShell, we can stream line the output that we get. Often times commands like these produce a lot of useless but useful information. It’s not useful at the moment. This is like our work enviroment. I use to be a big advacate of duel, and not more screens. I would often have 5 things going on at once. My desk use to have everything I needed to quickly grab and solve a personal problem. For example, my chapstick sat on my computer stand. My water bottle beside the monitor. Papers, sticky notes, and more all scattered accross my desk. I wondered why I couldn’t focus. Our brains are like batteries. How much focus is the charge. Our brains take in everything. Your brain notices the speck of dirt on the computer monitor and the sticky note, without your password on it, hanging from your monitor. This takes your charge.
Having two monitors is great and I still use two. However, I have a focused monitor and a second monitor for when I need to connect to something else. At some point I will get a larger wider monitor and drop the second one all together. Having less allows your brain to grab more attention on one or two tasks. Someone like myself, I have more than one task going at any moment. That’s ok with my brain. Let’s use our Select-object command in real life and remove the distractions from our desks.
In the intricate ecosystem of IT support, the quality of communication in ticket submissions can significantly influence the efficiency of problem resolution. Imagine walking into a dense forest, each tree representing a different issue or ticket awaiting resolution. Just as a seasoned guide can navigate these woods with ease, providing clear paths and descriptions, a Subject Matter Expert (SME) in IT can illuminate the way to swift solutions with well-crafted tickets.
The Spectrum of Ticket Details
Venture into the thicket of daily IT support tickets, and you’ll encounter a wide array of communication styles. On one end, there are tickets like faint, barely noticeable trails – vague, minimal details offered by users unsure of what information is pertinent. Bob from manufacturing, for example, might simply state, “My computer won’t turn on,” leaving the path to resolution obscured by underbrush.
Contrastingly, tickets from more technically adept users, like Jan from accounting, are akin to well-trodden paths through the forest, marked by signs and clear directions. Jan not only mentions reinserting cables and attempting to power on her computer but also notes the absence of the usual boot-up text, laying breadcrumbs for IT support to follow towards a solution.
Cafting a Map to Resolution
Subject Matter Experts (SMEs) stand as the rangers of this forest, armed with the knowledge and tools to guide others through even the densest undergrowth. Here’s how they can effectively chart the course:
Know Your Audience: Just as a ranger alters their guidance based on the experience of the hikers, SMEs should tailor their ticket submissions to the technical level of the IT support team. This ensures that the instructions are neither too complex for general support staff nor too simplistic for specialists.
Use a Structured Format: A structured ticket is like a map, offering a clear overview of the terrain at a glance. By organizing the issue, steps taken, and potential solutions logically, SMEs create a guide that others can follow easily, avoiding unnecessary detours.
Prioritize Clarity and Brevity: In the dense forest of IT issues, clarity acts as a beacon, guiding the support team directly to the heart of the problem. SMEs should aim to illuminate the path with precise, concise language, ensuring no one gets lost in unnecessary details.
Offer Potential Solutions: Suggesting solutions or workarounds is akin to marking potential paths on a map. While not all may lead directly to the destination, they provide starting points, accelerating the journey towards resolution.
Include Visuals When Necessary: Sometimes, the most effective way to describe a landscape is through visuals. Diagrams, screenshots, and videos can serve as snapshots of the issue, offering immediate context and understanding.
Encourage Open Communication: Ending a ticket with an invitation for questions is like leaving a trail of markers for others to follow, ensuring that if the path becomes unclear, further guidance is just a call away.
Navigating the Forest Together
In the realm of IT, “Subject Matter Expert Tickets” are more than just requests for assistance; they’re opportunities for SMEs to lead by example, demonstrating how detailed, well-structured communication can streamline the resolution process. It’s about creating a collaborative environment where every ticket, like a trail in the forest, is clearly marked and navigable, leading to a more efficient, effective IT support system.
By adopting these strategies, SMEs not only enhance their own credibility but also contribute to a culture of clarity and cooperation, ensuring that the vast forest of IT support is a little easier for everyone to navigate.
