How Do I Find My Windows Server 2012 Product Key

Before the era of cloud computing, Windows Server 2012 R2 was widely recognized as one of the best enterprise server software of its time, with numerous capabilities that you can use for personal or professional purposes. Because it’s a Windows operating system, you’ll need a valid product key to activate and use it. It will be in a trial state if you don’t have it, so you won’t be able to use it to its total capacity.

However, obtaining a product key for Windows Server 2012 R2 is simple. We’ll show you three ways to find the Windows Server 2012 Product Key in this guide.

  1. 1. Make use of the Windows Product Key Finder program.

  3. 3. Make use of the registry

#2. Find Windows Server 2012 Product Key Using CMD/PowerShell

Find Windows Server 2012 Product Key Using CMD

Turning to a privileged command prompt in Windows and running a command that retrieves the software licensing product key is the most straightforward approach to find the Windows Product Key license.

Step 1. Open a new Administrator Command Prompt window in Windows.

open command prompt

Step 2. After you’ve opened the cmd, type the following:

wmic path softwarelicensingservice get OA3xOriginalProductKey

enter command line

Step 3. To see the Windows product key, press Enter and Return. It’s a 25-character alphanumeric string with the following format:

XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

That is all there is to it. This procedure can be used to obtain the Windows product key on practically any Windows installation.

Recover the Lost Server Product Key in Powershell

Step 1. If you’re using Windows 10 PowerShell, the steps are the same as before. Select Windows PowerShell (Admin) from the context menu after right-clicking the Start Menu button.

open windows powershell

Step 2. At the prompt, enter this command to reveal the product key, as shown in Figure.

PowerShell «(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

enter command line in powershell

Step 3. Wait a few moments for PowerShell to display the licensing key for your current Windows operating system version.

#3. Find Windows Server 2012 Product Key in Registry

A product license key is an input into the installation wizard each time you install Windows. The Windows registry stores this key. Each time you load a Windows update, the product license is saved in the registry and reviewed. If the product key is invalid, you may have difficulty accessing certain operating system capabilities, and updates may be denied. If you’ve misplaced the packing, looking up the product ID in the registry will help you find it.

Step 1. Select «Run» from the Windows «Start» menu. Press the «Ok» button after typing «Regedit» into the text field. The Windows registry editor will open as a result of this.

Step 2. In the registry, look for the «HKEY LOCAL MACHINESOFTWAREMicrosoftWindowsCurrentVersion» key. This folder contains a variety of Windows-related configuration files for your machine.

Step 3. When you right-click the «ProductId» key, choose «Modify» from the context menu. Look at the displayed number. This is your Windows product key. To avoid changing the value, press the «Cancel» button.

Что делать если вы забыли ключ от Windows 10 или Windows 8? Как быть если предыдущий администратор не передал вам ключ от Windows Server 2012 R2? Ноутбук с Windows непонятной версии нужно откатить на заводские настройки, а ключ от операционной системы никто не помнит?

В зависимости от того, как вы получили свою копию Windows 10, для активации может потребоваться 25-значный ключ продукта или цифровая лицензия. 

  • Цифровая лицензия (в Windows 10 версии 1511 носит название цифрового разрешения) — это способ активации в Windows 10, который не требует ввода ключа продукта. 
  • Ключ продукта представляет собой 25-значный код, используемый для активации Windows. Вы увидите КЛЮЧ ПРОДУКТА: XXXXX-XXXXX-XXXXX-XXXXX-XXXXX.

Ключ продукта

Если у вас установлен ключ продукта, то можно его узнать. Просто скопируйте текст ниже в файл winkey.vbs и запустите на нужной машине. Если повезёт, то скрипт определит ключ и версию системы.

Ключ продукта в BIOS

Лицензионный ключ может быть прописан в BIOS устройства. Узнать его можно через Powershell:

(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

win

Или в командной строке:

wmic path softwarelicensingservice get OA3xOriginalProductKey

win

Цифровая лицензия

Если вы бесплатно обновили ОС Windows 7 или Windows 8.1 до Windows 10, вместо ключа продукта вы должны получить цифровую лицензию. Если у вас есть цифровая лицензия для устройства, вы можете переустановить тот же выпуск Windows 10 на этом устройстве без ввода ключа продукта.

В этом случае при попытке запустить скрипт для определения ключа вы получите это: BBBBB-BBBBB-BBBBB-BBBBB-BBBBB.

win

Открываем окно параметров.

Проверить состояния активации в параметрах

win

Надпись об активации может отличаться:

win

Ключ по умолчанию

Можно узнать ключ по умолчанию для текущей редакции. Он устанавливается, если вы не указываете свой ключ и сохраняется при получении цифровой лицензии.

Частично:

slmgr -dli
slmgr -dlv

win

Полную версия ключа можно посмотреть в реестре:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform\BackupProductKeyDefault

Скрипт VBS в помощь. Просто скопируйте текст ниже в файл winkey2.vbs и запустите на нужной машине. Скрипт определит ключ по умолчанию и версию системы.

Этот ключ позволит установить windows 10 без проведения активации. Потом автоматически должна активироваться цифровая лицензия, если она привязана к вашей учётной записи Microsoft.

  • From a PowerShell prompt, issue the following commands:

    . C:\users\administrator\desktop\key.ps1

    Get-WindowsKey

    There is a space character between the ‘.’ and the ‘C’ in the first line.  And you do not need the quotation marks around administrator, although I don’t think that was the issue.

  • i had used this script to get my product key but when i reuse to activate my new OS it fails; could you please advise what could be an issue.

  • You need to call Microsoft to see why your key is no longer working.  Some keys have a limited number of activations.  Maybe you have reached the limit.  Microsoft will be able to tell you.

Как узнать ключ продукта установленной операционной системы Windows? Конечно проще всего воспользоваться специализированными программами (ProduKey, ShowKeyPlus и т.п.), но мы не ищем легких путей 🙂 В поисках ключа нам поможет PowerShell.

Ключ продукта Windows хранится в системном реестре, в разделе HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion, в параметре DigitalProductID.

Примечание. На самом деле у Windows есть два ключа продукта. Кроме ключа активации есть еще ключ установки (generic), находящийся в разделе HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DefaultProductKey. С этим ключом можно установить систему, но нельзя ее активировать.

раздел реестра

Но просто так ключ посмотреть не удастся. Данные в DigitalProductID хранятся в двоичном виде, сам ключ занимает байты с 52 по 66. Кроме того данные зашифрованы в кодировке base 24.

параметр реестра

Для того, чтобы узнать ключ, надо извлечь его из реестра и расшифровать. Для расшифровки используем следующий PowerShell скрипт. Сознаюсь, скрипт не мой 🙂  Я нашел его на просторах интернета и немного подправил, а также добавил комментарии. Кстати, в скрипте активно используются побитовые операторы.

# 24 символа, использующиеся в ключах продукта Microsoft
$base24 = ‘BCDFGHJKMPQRTVWXY2346789’;
# длина ключа продукта в символах
$decodeStringLength = 24;
# длина ключа продукта в байтах
$decodeLength = 14;
# строка с расшифрованным ключом
$decodedKey = ″ ″;

#Извлекаем зашифрованный ключ из реестра и сохраняем его в массив

$digitalProductId = (Get-Item ‘HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion’).GetValue(‘DigitalProductId’)[52..66]

#Проверяем наличие в ключе буквы ‘N’ (для Windows 8 и старше)

#Если третий бит младшего байта массива равен 1, то в номере присутствует буква ‘N’
$containsN = ($digitalProductId[$decodeLength] -shr 3) -bAnd 1;

#Для корректной расшифровки номера этот бит необходимо сбросить
$digitalProductId[$decodeLength] = $digitalProductId[$decodeLength] -band 0xF7;

<# Расшифровка ключа. Заключается в том, что полученное из реестра значение $digitalProductId переводится в систему счисления с основанием 24, затем каждая цифра заменяется на символ из $base24, индексом которого является эта цифра #>

for ($i = $decodeStringLength; $i -ge 0; $i−−) {

# Переменная для хранения индекса текущего символа, перед началом вычисления обнуляем
$digitMapIndex = 0;

for ($j = $decodeLength; $j -ge 0; $j−−) {

<# Размерность в байтах, поэтому исходное основание 256. Умножаем на него остаток от предыдущей итерации и добавляем цифру из следующего разряда #>
$digitMapIndex = ($digitMapIndex -shl 8) -bXor $digitalProductId[$j];

<# Делим $digitMapIndex на количество символов в $base24. Частное попадает в $digitalProductId[$j],
а остаток от деления в $digitMapIndex #>
$digitalProductId[$j] = [System.Math]::DivRem($digitMapIndex, $base24.Length, [ref]$digitMapIndex);

}

# Находим в $base24 символ с полученным индексом и добавляем его в $decodedKey
$decodedKey = $decodedKey.Insert(0, $base24[$digitMapIndex]);

}

<# Если в ключе присутвует символ ′N′, то добавляем его. Для этого находим в расшифрованной строке первый символ и запоминаем его индекс в $base24. Затем удаляем первый символ, а в оставшуюся строку вставляем ′N′ в позицию с номером индекса удалённого символа #>

if ($containsN -eq 1) {

$index = $base24.IndexOf($decodedKey[0]);
$decodedKey = $decodedKey.Substring(1).Insert($index, ‘N’);

}

# Вставляем тире через каждые пять символов

for ($n = 20; $n -ge 5; $n -= 5){$decodedKey = $decodedKey.Insert($n, ‘-‘)}

# Формируем вывод, добавляем в него дополнительную информацию об операционной системе

$Target = [System.Net.Dns]::GetHostName();

Сохраняем код в файлик с расширением .ps1, запускаем и получаем результат. Готовый скрипт getproductkey.ps1.

вывод скрипта

Ну и чтобы убедиться в том, что скрипт работает правильно, проверим полученный результат с помощью программы ProduKey. Как видите, она выдает такой же ключ.
