In this case, clear the system partition. If you don’t have enough disk space, this could be the reason why the Microsoft Store doesn’t start.
Your computer then checks for updates that it finds, downloads and installs. Therefore, it is important to check for updates and install them if they are detected. Windows has received many updates recently. Since the Store is a Windows component, the Windows 10 Update Center will update your version of the Store.
If it still does not work, restart your computer and try again. I suggest you restart your shop and see if it opens. If you can’t open your shop the first time, don’t panic, it may only be temporary. Get the best apps from the Microsoft Store for Windows.
