I want to know the uninstallation process as my PC comes with several apps from the Microsoft Store installed out of the box, so tidying up my PC involves pruning those.
The apps in the start menu you can right click and uninstall. The others that don't give you an uninstall option you can unpin. Some things you chose to uninstall via the apps settings panel or in the Windows Store Windows will sometimes reinstall them later.
There is a program that can remove all windows apps & reinstall them if you regret it.
I can not remember its name but I saw it on Majorgeeks, months ago.
You should try to Google it, sorry I could not be more helpful.
I use Ccleaner which gets rid of most of the crap that Microsoft forces on you. https://www.ccleaner.com/ Firefox throws up a security warning when you go there for some reason but I have used Ccleaner for years without any problems. It is free although you can pay if you want.
