Question

Intune script that will check the uptime of each machine in the organization and restart laptop after checks

Christos Christopoulos 35

Hello everyone,

I need your help, please, because I’m feeling desperate. I want to create a detection and a remediation script in Intune. As a result, I would like it to check if the uptime of each machine reaches 5 days and send a warning to the user: “Your PC has been on for 5 days, please restart.” On the 6th day, the warning will say: “Save your work because in 10 minutes your PC will restart,” and then the PC will automatically restart (force restart).

Τhank you

@Christos Christopoulos Thanks for posting in our Q&A.

Honestly, I'm not familiar with writing a PowerShell script to make what you want. This issue seems more related to PowerShell. So, I will add "PowerShell" tag.

If there is any issue when you deploy scripts via intune, we will try our best to troubleshoot it. It is intune scope.

Thanks for your understanding.

Asked the following to Copilot and it came back with this:

Yes, you can use Microsoft Intune to track device uptime across your organization. While Intune doesn't directly provide an "Up Time" report, you can create a custom PowerShell script to gather this information and deploy it via Intune.

Here's a general approach:

Create a PowerShell Script: Write a script that retrieves the uptime of each device. You can use the Get-CimInstance cmdlet to fetch the uptime from the Win32_OperatingSystem class.

$uptime = (Get-CimInstance -ClassName Win32_OperatingSystem).LastBootUpTime $uptime_days = (New-TimeSpan -Start $uptime -End (Get-Date)).Days Write-Output "Uptime: $uptime_days days"

Deploy the Script via Intune: Use Intune to deploy this script to all managed devices. You can set up a detection and remediation script that checks the uptime and reports it back.

Generate Reports: Use Intune's reporting capabilities to collect and analyse the data. You can create custom reports to view the uptime information across all devices.

For more detailed steps and examples, you can refer to Microsoft's documentation on Intune reporting and PowerShell scripting.

Still don't know how we'd set this up in Intune though?

If you specificly want to restart computers each 6 days, I would seach and investigate how to do a Task with Task Scheduler using powershell and how to add the message system to it.

Another consideration is, may I ask why you want to do this? Could the reason be a Fast Start up still turned on by default. Just thinking, are you aware of this?

hello @Pavel yannara Mirochnitchenko Thank you for your help, and sorry for the delayed response.

We need this because many of our users don’t restart their PCs, so the updates we push either don’t apply or take too long. We’ve seen users with 10 days of uptime. Many of them just close their laptop lid and leave.

That’s why we need this. I’ve tried some tests via Intune, but it didn’t work. As you understand, we don’t want this to apply to everyone, like restarting every 3 days, but rather for the script to check the uptime of each computer, as some users are consistent and we don’t want to affect them.

If you could help me with either a script or with Intune, I’d really appreciate it.

Thank you
