Windows 10 how to clear apps that have not been installed in the app store

We know that the Win10 system also has an application store controlled by Microsoft, but there is a problem: in the case of purchasing an application but not installing it, these applications will always appear in the un-installed list. This problem has not been solved by Microsoft, but we can adopt a more compromise approach.

Solutions
For the Microsoft account login system, there is no longer a list of un-apped apps, because you have changed one account. But as long as you log in to the system using your original account, the list exists. Fortunately, the installation files that appear as unmounted applications are not stored on your computer.
The above is a trick to let the Win10 system app store have purchased un-installed apps disappear, mainly to meet the needs of users with obsessive-compulsive disorder. Of course, I hope that Microsoft can solve this problem as soon as possible.
