How to change Visual Studio 2017 License Key?

I want to remove my license key in visual studio 2017. how can i do it? I am trying to change the product key but I cant.

Well I found two possible solutions.

1. Setting new product key with StorePID.exe (MS Docs).

navigate to VS 2017 installation directory (C:\Program Files (x86)\Microsoft Visual Studio\2017\Enterprise\Common7\IDE)
start cmd as admin
execute StorePID.exe <your_new_product_key> <MPC>
maybe a restart

Possible Microsoft Product Codes (MPC) are:

2. Removing product key first and set new one.

open register editor
navigate to HKEY_CLASSES_ROOT\Licenses\5C505A59-E312-4B89-9508-E162F8150517 and delete it
exeute a repair installation of VS 2017
enter your new product key under Help > Register Product

It's not the best way to solve it, but faster than deinstall and install the complete IDE.

For VS 2015, a key is

HKEY_CLASSES_ROOT\Licenses\4D8CFBCB-2F6A-4AD2-BABF-10E28F6F2C8F

for what it's worth...

For VS 2019 the registry key is: HKEY_CLASSES_ROOT\Licenses\41717607-F34E-432C-A138-A3CFD7E25CDA

MPCs for VS 2019.

Visual Studio Enterprise 2019 09260
