Question

I recently notice that when creating powershell scripts that use the Add-WindowsFeature cmdlet from the ServerManager Module on Windows Server 2008 R2, there is an aqua-blue overlay that does not get cleared until the entire script is finished. For example, here is a screenshot of a script that uses the Add-WindowsFeature Web-Server command to install IIS:

The Collecting data… Start Installation… overlay stays on top of the console history and does not disappear until after the entire script is finished. Is there any way to get the console to re-paint itself or to disable the overlay?

Answer 1

This is just result of Write-Progress called internally by server manager cmdlets. If you want to make it silent – just change your $ProgressPreference to ‘SilentlyContinue’.

You can emulate this by using Write-Progress your self:

for ($i = 0; $i -lt 100; $i++) { 
    Write-Progress -Activity "Counting: $i" -Status "$i" -PercentComplete $i
    sleep 1 
}
