How to change Visual Studio 2012,2013 or 2015 License Key?


I have a Copy of Visual Studio 2012 Pro on my machine with a Serial key that i'm no longer suppose to use because i have to use another one. My problem is i keep Uninstalling Visual studio but the Registration information is still there after re-install and i cannot figure out which registry path i have to delete (i deleted a few) with no luck.

Is there a easy way to remove tha reg info or swap my keys?

The Best Answer is


I had the same problem and wanted to change the product key to another. Unfortunate it's not as easy as it was on VS2010.

The following steps work:

  • Remove the registry key containing the license information: HKEY_CLASSES_ROOT\Licenses\77550D6B-6352-4E77-9DA3-537419DF564B

  • If you can't find the key, use sysinternals ProcessMonitor to check the registry access of VS2012 to locate the correct key which is always in HKEY_CLASSES_ROOT\Licenses

  • After you remove this key, VS2012 will tell you that it's license information is incorrect. Go to "Programs and features" and repair VS2012.

  • After the repair, VS2012 is reverted to a 30 day trial and you can enter a new product key. This could also be used to stay in a trial version loop and never enter a producy key.

For those who will need to remove product key from Visual Studio 2015:

  1. remove registry key HKCR\Licenses\4D8CFBCB-2F6A-4AD2-BABF-10E28F6F2C8F
  2. repair Visual Studio installation

That's it, now you can change the product key if necessary.
