Hi, you can locate the Software Center by clicking your Start menu and typing Software Center directly into the search bar.
If the shortcut is missing from your search results, you should try to trigger the application by go to C:\Windows\CCM\SCClient.exe in File Explorer. This utility is the client-side interface for Microsoft Endpoint Configuration Manager, which your organization might use to deploy Amazon Enterprise Access. If your system has transitioned to modern management, you may need to look for the Company Portal app instead.
