How To Get Windows 7 Product Key For Free

Windows 7 is a widely used operating system, even though Microsoft officially ended its support in January 2020. Many people still prefer using Windows 7, as it is known for its stability and user-friendly features. To activate Windows 7 on your computer, you need a valid product key.

Here are some ways to get a Windows 7 product key for free:

1. Use the Windows 7 Product Key on the COA Sticker

If you purchased a PC with Windows 7 pre-installed, there should be a Certificate of Authenticity (COA) sticker attached to the computer or included in the documentation. This sticker contains the Windows 7 product key that you can use to activate the OS on your computer.

2. Find the Product Key in the Windows Registry

When you install Windows 7 on your computer, the product key is stored in the Windows Registry. Although the registry does not display the product key in plain text, you can still extract it using a third-party tool or a script. You can use a tool like ProduKey or a simple VBScript like this:

    Set WshShell = CreateObject("WScript.Shell")
    MsgBox ConvertToKey(WshShell.RegRead("HKLMSOFTWAREMicrosoftWindows NTCurrentVersionDigitalProductId"))

    Function ConvertToKey(Key)
        Const KeyOffset = 52
        i = 28
        Chars = "BCDFGHJKMPQRTVWXY2346789"
            Cur = 0
            X = 14
                Cur = Cur * 256
                Cur = Key(X + KeyOffset) + Cur
                Key(X + KeyOffset) = (Cur  24) And 255
                Cur = Cur Mod 24
                X = X - 1
            Loop While X >= 0
            i = i -1
            KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
            If (((29 - i) Mod 6) = 0) And (i <> -1) Then
                i = i -1
                KeyOutput = "-" & KeyOutput
            End If
        Loop While i >= 0
        ConvertToKey = KeyOutput
    End Function

Copy the code above and save it as a .vbs file. Then, double-click the file to run the script, and a message box will display your Windows 7 product key.

3. Use Free Windows 7 Product Key Lists

There are websites and forums that provide lists of free Windows 7 product keys. These keys might work temporarily, but they are not recommended as Microsoft may block them, and your Windows 7 installation might be flagged as non-genuine.

4. Upgrade to Windows 10 for Free

If you are using an older version of Windows, you can still upgrade to Windows 10 for free. Although the official free upgrade offer ended in 2016, the process still works for many users. To upgrade to Windows 10, follow these steps:

  1. Visit the Windows 10 download page.
  2. Click on Download tool now.
  3. Run the Media Creation Tool and accept the license terms.
  4. Select Upgrade this PC now and follow the on-screen instructions.

Your PC will upgrade to Windows 10, and your Windows 7 product key will be converted into a digital license for Windows 10.


It is essential to have a valid Windows product key to use all the features of the operating system without any restrictions. Remember that using cracked or non-genuine product keys can lead to performance issues, and you may not receive essential updates and support from Microsoft. The methods mentioned above can help you get a Windows 7 product key for free, or you can consider upgrading to Windows 10 for better security and features.
