function Get-WindowsKey {
## function to retrieve the Windows Product Key from any PC
## by Jakob Bindslet ([email protected])
param ($targets = '.')
$hklm = 2147483650
$regPath = 'SoftwareMicrosoftWindows NTCurrentVersion'
$regValue = 'DigitalProductId'
Foreach ($target in $targets) {
$productKey = $null
$win32os = $null
$wmi = [WMIClass]'$targetrootdefault:stdRegProv'
$data = $wmi.GetBinaryValue($hklm,$regPath,$regValue)
$binArray = ($data.uValue)[52.66]
$charsArray = 'B','C','D','F','G','H','J','K','M','P','Q','R','T','V','W','X','Y','2','3','4','6','7','8','9'
## decrypt base24 encoded binary data
For ($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
}
}
$win32os = Get-WmiObject Win32_OperatingSystem -computer $target
$obj = New-Object Object
$obj Add-Member Noteproperty Computer -value $target
$obj Add-Member Noteproperty Caption -value $win32os.Caption
$obj Add-Member Noteproperty CSDVersion -value $win32os.CSDVersion
$obj Add-Member Noteproperty OSArch -value $win32os.OSArchitecture
$obj Add-Member Noteproperty BuildNumber -value $win32os.BuildNumber
$obj Add-Member Noteproperty RegisteredTo -value $win32os.RegisteredUser
$obj Add-Member Noteproperty ProductID -value $win32os.SerialNumber
$obj Add-Member Noteproperty ProductKey -value $productkey
$obj
}
}

After copying, open notepad > paste the query > and then save it as a .ps1 extension file. Let’s say save it as “Windows7Key.ps1” at the desktop. After that, run the PowerShell console as an administrator, then input the following command: Star wars empire at war forces of corruption serial key 2017.

After pressing Enter / Return, and confirming by pressing “Y” (Yes) to commence, issue the command below. Note that you should change “USERNAME” to your username and the “Windows7Key.ps1” to the name of .ps1 file of your liking.

Now if you don’t feel doing those things, there’s always a software to back you up. The Magical Jelly Bean is an easy to use key finder to check out your Windows OS’ product key, and it could also retrieve 300 more keys from other popular programs too. I use this sparingly, whenever I need to reformat for science purposes. Just follow the instructions from the link and the installation procedures to get started. Just make sure to un-check the “Razor Web” extension add-on so you wont install it accidentally. It sucks, and is a potential adware.

So there you have it. Easy right? Just remember that Microsoft started on their licensing terms that the OEM key and Retail key differs. Both might be the same, but the terms of usage differs even though you’ve found your key. For example, the OEM based key provided is intended to be used on the PC or notebook you received your copy of Windows with so legally, you can’t use it on other PCs. For the retail version, it’s all up to you.
