Reset your device with a simple app
Problem definition
Recently at a customer I was asked if it was possible, in preparation for their new modern workplace, that the end user could reset his device himself. Basically, the same as the famous "wipe" button in Intune.
I had indicated that this can be done by means of the following ways:
- End user goes to the Settings app ➡️ Update & Security ➡️ Recovery ➡️ Get Started and follow the wizard
- End user chooses CTRL + Windowskey + R on the sign-in screen
- In the Run field, type
systemreset.exeand follow the wizard - Oh.. and the last option is to open the Company Portal ➡️ Devices ➡️ This Device ➡️ Actions ➡️ Reset
A requirement of the customer was that the end users may not be a local admin, so option 2 is dropped. They also wanted to protect the end user from the unnecessary questions that arise when choosing options 1 and 3. So they also fall off. Option 4 is to many clicks for the end-user. So there is nothing left. But we still want to offer a service with which the user can reset his device.
🤔
So, how does Intune work?
I don't know if I can judge this as a command, but after some research I ended up on this forum post: https://techcommunity.microsoft.com/t5/windows-deployment/factory-reset-windows-10-without-user-intervention/m-p/1349038/highlight/true#M559. There is a piece of script there that Intune also uses in theory. So if we can cram that piece nicely into a Win32 app with a nice warning?
💡💡💡💡💡
The win32app
The win32app is really nothing more than a powershell script. For the sake of simplicity, I will divide it in two.
Part 1: Warning window
As soon as the end user presses install, the script starts immediately without any kind of warning. So perhaps so neat to at least provide the end user with a warning and some tips before continuing.
For this I use the System.Windows.Forms language to create a popup containing the text, two buttons, and their formatting. I will not go into more detail here, except that you can add a title bar icon yourself by means of a base64 code. Websites enough that can do this for you.

The magic
The end user has received a warning window with two buttons. A CONTINUE and a CANCEL button. But what happens when the end user presses the CONTINUE button?
Well...
Do you have a moment?
⏱️⏱️
Time is up.
As soon as you press the CONTINUE button, the following script will take effect. This script is based on the local MDM WMI Bridge Provider.
$okButton = New-Object System.Windows.Forms.Button
$okButton.Location = New-Object System.Drawing.Point(75,300)

$session.InvokeMethod($namespaceName, $instance, $methodName, $params)
}
If you press the CANCEL button, the warning window is closed, and nothing happens to that particular device.
'No' {
# Dispose the form and its controls. Skip, if you want to redisplay the form later.
$form.Close()
$stream.Dispose()
$form.Dispose()
exit
}
}
Create and deploy
I do think we all know how to make a win32app these days, so I'll skip that, but I'll tell you what you need to do in Intune to deploy the app.
- Go to the Enpoint Manager portal
- Go to Apps ➡️ Windows and click on + Add
- In the dropdown list, select Windows app (Win32)
- Click on Select
- Click on Select app package file
- Browse to the intunewin file, that you created or downloaded from my GitHub
- Click on OK
- Fill in a Name, Description and the Publisher. If you want you can fill in the rest of the fields as well
- Click on Next
- At the Install command field, type this:
.\serviceui.exe -process:explorer.exe "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -ExecutionPolicy Bypass -WindowStyle Hidden -NoLogo -NoProfile -File ".\Reset-MDMWipeDevice.ps1" - At the Uninstall command field, type this:
cmd.exe /c del %ProgramData%\TheOrangeCat\ResetMDMDevice\Reset-MDMWipeDevice.ps1.tag - Leave the rest as default
- Click on Next
- Choose at the Operating System architecture for 64-bit
- Choose at the Minimum operating system a value that suits your environment
- Click on Next
- From the Rules format dropdown, select Manually configure detection rules
- Click on + Add
- At the Rule type dropdown, select File
- In the Path field, type
%ProgramData%\TheOrangeCat\ResetMDMDevice\ - In the File or folder field, type
Reset-MDMWipeDevice.ps1.tag - From the Detection method dropdown, select File or folder exist
- Click on OK
- Click on Next
- Click on Next
- Click on Next
- On the Assignments tab, choose an Azure AD group with your users and select them as avaialble.
- Click on Next
- Review your settings and click on Create
App in action
In the video below you can clearly see what the end user will see as soon as he / she installs the app.
