How To Find Windows Server Product Keys

Find Lost Product Keys in Windows Server 2012, 2008, & More.

If you find yourself here, I’m guessing that you’re an IT expert, a computer Engineer or an administrator in charge of the Windows Server environment at your company.

I’m also guessing that you need to reinstall Windows Server but you can’t find the product key. Don’t be afraid, my tech friend. As long as Windows Server is still installed, even if it’s not working but still on a network accessible drive, you’re probably in luck.

There are numerous special tools, called “key finder programs”, which are basically designed to extract the encrypted Windows Server product key that is stored in the Windows Registry, very few of these programs can even do so remotely.

These procedures below should only take a few minutes and it works well in finding lost product keys from installations of Windows 8 & 8.1, Windows 7, Windows Vista, Windows Server 2012/2008/2003, including R2 versions, Windows XP.  These steps also work for Windows 2000, Windows NT, Windows ME, Windows 98, and Windows 95, which I basically think they are outdated.

How to Find Windows Server Product Keys

1. Download Belarc Advisor: Belar works similarly to system audit/information tool if you have ever used it before. If not, don’t worry, it’s not complicated.

   Note: Other key finders may work very fine for your Server version of Windows as well, but We have tested Belarc very well in Windows Server environments.
    

2. Install Belarc Advisor. It’s a small program, user friendly; it doesn’t interrupt any other programs or services running on your Window Server computer.
    
3. Launch Belarc Advisor and wait while it completes the analysis. This might take some minutes or more, especially if you have a computer that is slow.
    
4. Locate the Windows Server product key in the Software Licenses area of the results that Belarc displays, which you may have noticed is inside a browser window.
    
5. Your Windows Server key must be a 25-character, alphanumeric code, in 5 sections of 5 characters, as in xxxxx-xxxxx-xxxxx-xxxxx-xxxxx format.

   Note: The only exception to this is the Windows NT product key, which is only 20 characters long and looks like xxxxx-xxx-xxxxxxx-xxxxx.
    

6. Record your valid Windows Server product key in your existing technology audit documentation or somewhere else where you and your team won’t lose it.
