Accepted Answer

```
Write-Output "- Kill all IE windows"
get-process iexplore | stop-process -Force
Start-Sleep -s 1
```

function that open IE for a given url and a password retrieved from encrypted file

```
function OpenIE([string]$url, [string]$p)
{
```

Open Internet Explorer with a given url

```
$wshell = New-Object -com WScript.Shell
$wshell.Run("iexplore.exe $url")
Start-Sleep 1
```

Send user credentials to IE

```
$wshell.sendkeys("+{TAB}")
$wshell.sendkeys("username")
$wshell.sendkeys("{TAB}")
$wshell.sendkeys($p)
$wshell.sendkeys("{ENTER}")
}

$credentialsfile = "C:	emp\credfile.txt" 
```

Check if credential file exists

```
if (Test-Path $credentialsfile)
{  
```

Retrieve the credentials from an encrypted file

```
$encp = get-content $credentialsfile | convertto-securestring 
$ptr = [System.Runtime.InteropServices.Marshal]::SecureStringToCoTaskMemUnicode($encp) 
$p = [System.Runtime.InteropServices.Marshal]::PtrToStringUni($ptr) 
remove-variable encp,ptr 
}else{
```

Request credentials and save to encrypted file

```
$creds = Get-Credential –credential DOMAIN\user
$encp = $creds.password 
$encp |ConvertFrom-SecureString |Set-Content $credentialsfile
}

Write-Output "- open IE"
OpenIE "http://www.yoururlhere.com" $p
```
