There is Windows S Mode where you can only run Windows Store apps and only use Microsoft Edge. That should qualify for "proper sandboxing", shouldn't it?

Then again, no one who needs an actually useful computer runs Windows in S mode.

That's because of all useful apps for Windows are not sandboxed. This is where the apps vendor have to do the required work but they are too lazy to do that.

Sandboxing itself makes the apps not useful.
