Microsoft Store is not supported on Windows 7. It is only available on supported versions of Windows (such as Windows 10 and Windows 11). Because of this, Microsoft Store itself cannot be installed or used to download apps and games on a Windows 7 Dell laptop.
The troubleshooting steps in the provided materials (resetting Microsoft Store with wsreset.exe, using the Store troubleshooter, reinstalling apps from My Library, using winget, checking Store policies, etc.) all apply only when Microsoft Store is already present on a supported Windows version. They do not apply to Windows 7.
To use Microsoft Store and install apps and games from it, the device must be running a supported Windows version that includes Microsoft Store (for example, Windows 10 or Windows 11). On Windows 7, Microsoft Store cannot be added or made to work through downloads from a browser or other tools.
