Sometimes it can be convenient to be able to retrieve the Windows Product key from an active Windows installation e.g. if you have lost your Windows COA Sticker or if you can’t read the sticker anymore because it has been damage. I have developed a little tool in Visual Basic that can help you to retrieve your Windows Product key from the registry on an active Windows installation. With this tool you can find your Product Key before you reinstall your system to be sure that you are able to reactivate your Windows license. No installation is required and there is no catch like in form of toolbars or hidden ads. It is just a single .exe file that you can put on a USB stick and bring with you wherever you go.
The format of a Windows Product key is in most cases a 25 characters looking like this:
XXXXX-XXXXX-XXXXX-XXXXX-XXXXX
Download GetWinKey
You can download GetWinKey from my download section *
*.Net Framework 3.5 is required to run this tool.
Supported platform:
- Windows 7
- Windows 8
- Windows 10
- Windows Server 2008
- Windows Server 2008 R2
- Windows Server 2012
- Windows Server 2012 R2
- Windows Server 2016
Both x86 and x64 platform is supported

It is really helpful for me. Now I can easily retrieve my windows key. Thanks to you for that.
I can’t explain how helpful this article was to me. Though it doesn’t matter, I just wanted to ensure whether this trick is legit. I mean will I have to face other problems in future? Anyway thanks for sharing.
Hi
This trick is totally legit. All this tool does is to read your key out of the registry where it is stored encrypted. It is the same key as the one you entered when you installed Windows.
Thanks Thomas you saved my day. I have laptop which comes with Windows 7. I always wanted to fresh install Windows on it but I feared the key. Now I will retrieve the key using your method. Thanks a lot again.
I was thinking that retrieving Windows Product Key from Registry is quite impossible for me.
