Replace first character in PowerShell

I have to replace the first character in a string. I have a snippet like this:

 if(!([string]::Compare($filestmp.Substring(0,1), "M", $True)))
 {
     echo cos
     $filestmp = $filestmp.Replace('^(.*?)M(.*)', 'Zmodyfikowany  ')
 }

The code doesn't throw any exceptions, and it doesn't work either. The if condition passes, since my echo statement is printed. What am I doing wrong here?

Other solution:

$filestmp = "M Log.txt"

# Test equal which ignores case
if ($filestmp.Substring(0,1) -ieq "M")
{
    $filestmp = "'Zmodyfikowany{0}" -f  $filestmp.Substring(1)
}

# Test like which ignores case
if ($filestmp -ilike "M*")
{
    $filestmp = "'Zmodyfikowany{0}" -f  $filestmp.Substring(1)
}

RegEx is overkill.

Use a simple substring:

$filestmp=("Zmodyfikowany" +  $filestmp.SubString(1) )
