This is strange issue J'ai observed. J'ai installé Active Python 2.7 on Windows 10 (version 1903).
On typing “python” from search, opens the Python 2.7 prompt but when I type from invite de commandes window, it triggers the Microsoft Store.
Don't know how to fix it and this never happened on previous versions of Windows (RS5, RS4…)
Edit 2: Please suggest the solution to turn this off: either via invite de commandes or using answer file to get this after unattended installation.
