Agreed. One day I realized my computer was completely out of space, was barely still running. Turns out Microsoft store had dutifully downloaded many copies of a game until the entire drive was full. Uninstalling got rid of only one copy of the files. Store said it was no longer installed even though all the files of many copies were still there. Deleting them manually was a horrible mess of permissions issues, involving the need to edit the registry and things too. I think I ended up needing to boot into Linux from a usb stick to finally fix everything up. Anyways, steam for me if I have the choice. Let me just delete files if I need to Microsoft, geeze.
