This will read the file and replace any of the matching strings with a blank line and then write it back to the file.

$file = Get-Content C:\path\to\file.txt

$file | Foreach-Object {
    if ( ($_ -match "\[stderr\]") -or ($_ -match "\[stdout\]") -or ($_ -match "Enable succeeded:")) {
        $file[$file.IndexOf("$_")] = ''
    }
}

$file | Set-Content C:\path\to\file.txt
