Find your Visual Studio Product Key through the Registry

Posted: December 16, 2010 by phenom97 in Uncategorized

Hey all. I was looking through my registry yesterday when I stumbled upon how to find Visual Studio product keys using the Windows Registry. This should work for any Visual Studio edition (2008, 2010 etc), so here is the registry key you need.

HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432Node -> Microsoft -> VisualStudio -> 10.0 -> Registration -> 2000.0×0000 -> PIDKEY

The above path will take you to the Visual Studio 2010 Product key. For Visual Studio 2008, simply change 10.0 to 9.0 and then you’re done. In the 2000×0000 key, click on the string “PIDKEY” and there is your product key for Visual Studio.

For Visual Studio 2008

HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432Node -> Microsoft -> VisualStudio -> 9.0 -> Registration -> 2000.0×0000 -> PIDKEY

For Visual Studio 2005

HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432Node -> Microsoft -> VisualStudio -> 8.0 -> Registration -> 2000.0×0000 -> PIDKEY

For Visual Studio.NET

HKEY_LOCAL_MACHINE -> SOFTWARE -> Wow6432Node -> Microsoft -> VisualStudio -> 7.0 -> Registration -> 2000.0×0000 -> PIDKEY

This is really handy if you lost your Visual Studio product key and you need to reinstall or reactivate your copy of Visual Studio.

…or you could just use a keyfinder, like LicenseCrawler of the Magical Jellybean Keyfinder which comes in a Free version.
