<#If you’ve misplaced your Sql Server installation key, you can retrieve it from the Windows Registry using a 
powershell script posted here.  However, that script works only for Sql 2008; in 2012, the location of the key 
in the Registry has changed, as well as the format. So I’ve posted my modification of the powershell script below:
For SQL 2014, change 110 to 120 in the registry path#>

function Get-SQLserverKey {
## function to retrieve the license key of a SQL 2012 Server.

param ($targets = ".")
$hklm = 2147483650
$regPath = "SOFTWARE\Microsoft\Microsoft SQL Server\110\Tools\Setup"
$regValue1 = "DigitalProductId"
$regValue2 = "PatchLevel"
$regValue3 = "Edition"
Foreach ($target in $targets) {
$productKey = $null
$win32os = $null
$wmi = [WMIClass]"\\$target\root\default:stdRegProv"
$data = $wmi.GetBinaryValue($hklm,$regPath,$regValue1)
[string]$SQLver = $wmi.GetstringValue($hklm,$regPath,$regValue2).svalue
[string]$SQLedition = $wmi.GetstringValue($hklm,$regPath,$regValue3).svalue
$binArray = ($data.uValue)[0..16]
$charsArray = "B","C","D","F","G","H","J","K","M","P","Q","R","T","V","W","X","Y","2","3","4","6","7","8","9"
## decrypt base24 encoded binary data
For ($i = 24; $i -ge 0; $i--) {
$k = 0
For ($j = 14; $j -ge 0; $j--) {
$k = $k * 256 -bxor $binArray[$j]
$binArray[$j] = [math]::truncate($k / 24)
$k = $k % 24
}
$productKey = $charsArray[$k] + $productKey
If (($i % 5 -eq 0) -and ($i -ne 0)) {
$productKey = "-" + $productKey
}
}

    You can make line 19 shorter using this:
    $charsArray = “BCDFGHJKMPQRTVWXY2346789″.toCharArray()
