Hi there,
I'm Cherrelyn and I’m happy to help you with this. To install Windows Maps (Microsoft Maps) on Windows 10 64-bit just open Microsoft Store from the Start menu. In the search bar, type “Windows Maps” and select from the results and click Install. Once installed, you can launch it directly from the Start menu.
Let me know if you don’t see the app in the Store and I can guide you through an alternative method.
Warm regards,
Cherrelyn
