"Double-Click" an icon on the desktop with a Script.

"Double-Click" an icon on the desktop with a Script.

I have this script below. That replaces a string in a file on each computer listed on the CSV file.
after the string has been replaced on a computer,  I would like it  to execute(Double-Click) on an icon located on the Desktop  , lets say the name of the Icon is "DoubleClickhere"

Thank you

## csv file with machines and user names to process:
$csv = 'c:\Scripts\Computers.csv'
## Absolute local file path on the clients:
$filePath = 'C:\test.txt'

$pattern = '(-username\s+)\S+'
Import-Csv -Path $csv | ForEach-Object {
	$computer = $_.ComputerName.Trim()
	$newUser = $_.NewUsername.Trim()
	$fileUNC = "\\$($computer)\$($filePath.Replace(':', '$'))"
	Write-Host "Processing $($computer), new user '$($newUser)' ..." -NoNewline
	Try {
		$content = Get-Content -Path $fileUNC -ErrorAction Stop
		$content -replace $pattern, "`$1$($newUser)" | Set-Content -Path $fileUNC -Force -ErrorAction Stop
		Write-Host " OK" -ForegroundColor Green
	} Catch {
		Write-Host " FAILED: $($_.Exception.Message)" -ForegroundColor Red
	}
}
