Find Windows 10 License Number
Posted : admin On 5/22/2019
If you're preparing to reinstall a program or an operating system (like a clean install of Windows), you'll need to find your unique product key (CD key) or serial number before continuing.
Normally this product key is located on the original install disc, or maybe in your order confirmation email. If you've lost your product key, you can often find it in the Windows Registry but this can be difficult, or sometimes even impossible, to do. Fortunately, there are many free key finder programs available to help.
Please read our Key Finder Programs FAQ for lots of helpful information. This isn't an easy topic, especially if you're new to it.

Secret games movie 1992. Honestly, I didn't care much for Product Key Informer. I think it was the baked-in fields for specific product keys that bothered me. It's a waste of screen real estate and confirms that the program's product key finding abilities are very limited.

Important Product Key Finder Information (Windows Product Keys)
If your system was purchased with Microsoft Windows pre-installed and you have not reinstalled it or upgraded it yourself, a key finder may only find the generic product key that your PC manufacturer used to install Windows. This product key may not work when attempting to reinstall Windows. In this case, you must use the unique product key that is on the sticker attached to your computer case.
If you can't locate your product key sticker you'll need to request a new Windows product key.
At the recent Microsoft Cloud Roadshow here in Toronto, team CANITPRO was provided the opportunity to present best practices surrounding Windows 10 security, manageability and deployment.
During the session entitled Taking Advantage of the New Deployment Features in Windows 10 the following question was asked:
'How do you find the Windows 10 product key once the upgrade from Windows 7, 8 or 8.1 is completed.'
Now traditionally, all that is required to retrieve this information is using the inventory capability via the Mobile Device Management software of choice. Another option has been made available via third party applications. Be careful when pursuing this route as reports have come forward that some third party applications install adware/malware during the installation of the tool. In either case, what has been discovered in some cases using both methods is the key provided is actually a generic key akin to one of the following:
- Windows 10 Enterprise: NPPR9-FWDCX-D2C8J-H872K-2YT43
- Windows 10 Pro: VK7JG-NPHTM-C97JM-9MPGT-3V66T
- Windows 10 Home: TX9XD-98N7V-6WMQ6-BX7FG-H8Q99
The trouble with using these keys, should you need to re-enter said key in future, is that it enrolls said Windows 10 installation into Insider Preview. While ok in a lab environment, Insider Preview could be troublesome in a production environment.
Enter Chris Goulard, IT Analyst and member of the #CANITPRO community on Twitter, with a solution via script to provide the actual Windows 10 key provide after upgrade. The script is as follows:
Set WshShell = CreateObject('WScript.Shell')
MsgBox ConvertToKey(WshShell.RegRead('HKLMSOFTWAREMicrosoftWindows NTCurrentVersionDigitalProductId'))
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
Simply copy and paste the above script into a new notepad file. Name the notepad file what you wish, however change the extension from .txt to .vbs. Save and run the newly created Key Catcher on a toolset USB key or right on the newly upgraded machine itself and the true key will be provided.
Thank you Chris for the share.
