It is requested a basic perspective for scripts on a functional aspect therewith

Question

In the event of having to employ a script to stabilize a safety setting in the registry which conflicts occasionally from the existence with an alternate user account;

the script is based on checking every one minute the specific value and repairing it when it is detected with error, a round of starting and sleeping indicates that the script will be active continually after once be executed?

What if at a point need be to do away with the specific script? Is it enough to simply delete the ps1 file from the 'scripts' folder?

Answer 1

One option would be to define scheduled task that runs at system startup and executes a Powershell script.

Here's a sample script that will save the registry value when it starts and will reset it if it ever changes. You will need to modify it to refer to the registry value that you need to monitor.

Function LogIt($msg) {
    "{0} - {1}" -f (Get-Date), $msg | Write-Host 
    "{0} - {1}" -f (Get-Date), $msg | Out-File -FilePath $log -Append
}

# Define the log file name and the registry to monitor
$log = "c:\scripts\Monitor.log"
$KeyName = "HKLM:\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\"
$ValueName = "UpdateDesiredVisibility"

LogIt "Monitor starting."
$wur = Get-ItemProperty $KeyName
$DesiredValue = $wur.($ValueName)
LogIt "Initial value is $DesiredValue"
while ($true) {                             # infinite loop to monitor value 
    Start-Sleep -Seconds 60
    $wur = Get-ItemProperty $KeyName 
    if ($wur.($ValueName) -ne $DesiredValue) {
        Logit "Value changed to $($wur.UpdateDesiredVisibility). Reset to $DesiredValue."
        Set-ItemProperty $KeyName  -Name $ValueName -Value  $DesiredValue
    }
}

Run the task as the system account identity so that it executes "in the background". If you need to stop it, use the task manager to kill the Powershell process.
