yep this problem has been solved on Android and iOS where the only place to install software is the App Store.

Windows did try to incite devs to use the windows store but it did not catch on. Restraining third-party installation only from the Store is a good way to remove adwares and co.

Honestly Microsoft did shat the bed with their app store, it has no right to be as difficult to use (both as user and developer) as it is.

One of the big reasons that the Microsoft store failed so hard was the absurd cut Microsoft wanted (30%).

Windows developers were and are already doing app distribution. 30% for something dev's were already doing...

Numerous android apps were found to be doing dodgy things after the fact. Probably ios ones too. It's not foolproof.
