There are some possible ways to display the Windows product key yourself. If you are using Windows 7 or earlier, the system is activated through a single product key stored in the Windows registry. You can easily extract this key using third-party software or simple scripts. You can then use this key to install Windows again on the same computer, or you can use it to install Windows on another computer. If you get lost or cannot find your product key, use these following ways to find your Windows 7 Product Key:
- Method 1: Check the Certificate of Authenticity (COA) sticker
- Method 2: Use a simple VB Script
- Method 3: Use a Product Key Finder software
Method 1: Check the Certificate of Authenticity (COA) sticker
Generally, if you purchased a physical copy of Windows, the product key should be on a label or card in the box that came with Windows. If Windows is pre-installed on your PC, the product key should appear on a label on the device’s Certificate of Authenticity (COA) label.
Microsoft product keys are often located on a product key sticker on your computer, as shown in the following example:
If the label does not exist or is damaged, the product key can still be retrieved. Try the following methods.
Method 2: Find Windows 7 Product Key using a simple script
Step 1: Launch Notepad. Click Start and type Notepad, then open it.
Step 2: Copy and paste the following into a Notepad window:
Copy and paste this code into Notepad:
Set WshShell = CreateObject("WScript.Shell") MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId")) Function ConvertToKey(Key) Const KeyOffset = 52 i = 28 Chars = "BCDFGHJKMPQRTVWXY2346789" Do Cur = 0 x = 14 Do 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
Step 3: Select File > Save As. Change the “Save as type” to All Files.
Step 4: Name the file productkey.vbs and click Save. It is recommended to save to the desktop for easy access.
Step 5: Once the file has been saved, double-click the file, and the popup window will show the product key.
When the popup is active, use Ctrl + C, it will copy the contents of the window to the clipboard, and then you can paste it into Notepad or elsewhere.
Warning: This method is not very accurate, which means that the script may sometimes show the wrong product. Therefore, we recommend that you use the Product Key Finder instead of this script method.
