Try this one.

# Get the current date and time
$currentDate = Get-Date

# Get the last reboot time of the system
$lastReboot = Get-CimInstance Win32_OperatingSystem | Select-Object -ExpandProperty LastBootUpTime

# Calculate the time difference between the last reboot and the current time
$timeDifference = $currentDate - $lastReboot

# Check if the time difference is greater than 6 days
if ($timeDifference.TotalDays -ge 6) {
    Write-Host "System last rebooted more than 6 days ago. Rebooting now..."
    Restart-Computer -Force
} else {
    Write-Host "System reboot is not required."
}

With the eval code I simply have Exit 1

There is the worklet to check in a restart is required as well! I like to run that after patch days just to make sure the reboots actually happen lol!

My script is functional. If you run it on powershell it works fine. My issue is getting it to work with Automox, in that remediation and execution. I did try Exit 1 in the Evaluation code, no dice.

If i put the restart-force on the script, it won’t get me to the deferral options below, which is exactly what i need from automox. Otherwise i’d just leave a running script on the machines

 

Using the deferral your exit code needs to be 0. In eval just go Exit 1. Remediation should exit 0 IF the pc needs rebooted. That should trigger the deferral popup.  

That’s exactly what i (think i am) doing right here,  or am i missing something?

So now i got Exit 1 on the Evaluation Code and this on the Remediation Code

# Get the last boot up time
$lastBootUpTime = (Get-CimInstance -ClassName Win32_OperatingSystem).LastBootUpTime

# Get the current date and time
$currentDate = Get-Date

# Calculate the time difference in days
$daysSinceLastReboot = ($currentDate - $lastBootUpTime).Days

# Check if the last reboot was more than 7 days ago
if ($daysSinceLastReboot -gt 7) 
# If yes, exit to remediation
{
   exit 0
}
else
{
   Write-Output "The computer is good."
}

Still no dice, the popup shows up whether the laptop has a reboot under 7 days or over 7 days

Does this work? Still with Exit 1 in Eval

# Get the last boot up time
$lastBootUpTime = (Get-CimInstance -ClassName Win32_OperatingSystem).LastBootUpTime

# Get the current date and time
$currentDate = Get-Date

# Calculate the time difference in days
$daysSinceLastReboot = ($currentDate - $lastBootUpTime).Days

# Check if the last reboot was more than 7 days ago
if ($daysSinceLastReboot -gt 7) 
{
   exit 0
}

# If the last reboot was within the last 7 days, exit with code 1
exit 1

No dice. When i run the policy with that, the Activity Log immediately gives out this: 

Think the issue might be with the Automox deferral popups. I may just need coffee, but I think the pop up upon ANY successful remediation, either exit 1 or 0. I have this that will give just a normal pop up 3 times every 3 hrs(can bed edited of course) that is a yes or wait? Can try that, no Automox pop ups, still exit 1 for eval etc.. After that my depth might have been hit hahaah!!

# Function to prompt user for reboot
function PromptForReboot {
    $caption = "Reboot Required"
    $message = "A reboot is required. Do you want to reboot now?"
    $yes = New-Object System.Management.Automation.Host.ChoiceDescription "&Yes", "Reboot the computer now."
    $wait = New-Object System.Management.Automation.Host.ChoiceDescription "&Wait", "Postpone the reboot for 3 hours."
    $options = [System.Management.Automation.Host.ChoiceDescription[]]($yes, $wait)
    $result = $host.ui.PromptForChoice($caption, $message, $options, 0)
    return $result
}

$rebooted = $false
$attempts = 0
$maxAttempts = 3

while (-not $rebooted -and $attempts -lt $maxAttempts) {
    $choice = PromptForReboot

    switch ($choice) {
        0 {
            Write-Output "Rebooting now..."
            Restart-Computer -Force
            $rebooted = $true
            break
        }
        1 {
            $attempts++
            Write-Output "Reboot postponed. Attempt $attempts/$maxAttempts"
            Start-Sleep -Seconds (3 * 60 * 60)  # Wait for 3 hours
            break
        }
    }
}

if (-not $rebooted) {
    Write-Output "Maximum attempts reached. Reboot postponed."
}

Oh and @jack.smith has this post that has the PC toast notification as well! 

Tested that out on a powershell, popup came askong me to reboot, even tho my laptop’s last reboot was yesterday

Add in some logic in the Worklet to tell you what’s going on. Example

Write-Output "Last Boot Up Time: $lastBootUpTime ($daysSinceLastReboot)"

Also examine C:\ProgramData\amagent\amagent.log at the time the worklet executes (need to know the worklet ID which can be found in the URL of the worklet). Or just gage based on time.
