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?
Thanks

Go to "Programs and features" and repair visual studio 2015. After the repair, visual studio 2015 is reverted to a 30-day trial and you can enter a new product key.
Please check this doc: How to: Locate the Visual Studio Product Key and usually we can look for the product key from the installation media (if applicable), on the My.VisualStudio.com website or Documentation or other communication from the vendor from whom you purchased the software.
Look in the registry under key: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\VERSION\Registration\SOMETHING . The key should be located inside the value named PIDKEY or ProductID .
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.
