I noticed today when installing an app from the Microsoft store on my computer running Windows 10 that the app did not need administrator permission to install.
Normally when installing apps/programs from downloaded executables or installers the UAC window pops up to request my admin password before it is allowed to proceed. Even program updates often involve the UAC pop-up. I prefer things this way since my computer is occasionally used by people who I trust enough to use it, but not enough to install things or change important settings.
This question covers how to prevent users from installing apps from the store, but that's not what I'm wondering.
What is different about installing an app from the Microsoft store versus other methods that allows the app to install without admin permission? Is it that the installation process is different for those apps, or does the Store itself has special permissions?
