If you are encountering this problem, then you are in the right place. It could get very frustrating when the Microsoft Store closes immediately after opening, especially for users who use it on a daily basis.
Products found in the Microsoft Store must be certified by Microsoft, so users trust the Store more and often get their apps here rather than downloading them from unknown sites. It became the common distribution center for apps, digital music, digital video, and e-books. However, with Windows 10, Microsoft combined the app store with the Windows Marketplace, Xbox Video, Windows Phone Store, and Xbox music, calling them the Microsoft Store. It was introduced in Windows 8 and Windows Server 2012 as the app store where users could download Microsoft apps. The Store became a core component of Windows. The Microsoft Windows Store was one of the most significant additions Microsoft made during the transition from Windows 7 to Windows 8.
