Why didn’t Microsoft include The store in windows 7? I can see that there is no store app on win7. Why didn’t Microsoft include this??? It will be useful because of security. (Maybe)
Support has long ended for Windows 7.
And when later operating systems ended their support, Windows 8, Windows 8.1, their access to the Store ended, too.
And as we do not work for Microsoft, we have no connection to what Microsoft does in relation to release dates of anything.
If you really want to find our why, I suggest that you ask Microsoft:
"Microsoft office locations around the world"
https://www.microsoft.com/en-us/worldwide.aspx
"Global Customer Service phone numbers"
