In Windows 10, and 11 (I think but haven't tried) if you mouse over the top bar of any window then right click you will get a little pop up that gives you 5 options, the last being " x Close   Alt+F4" and if you left click on that last item the window will close. You can tryu it on your browser, or on any open window. Nothing to it.

As for Intuit, they are simply trying to force all users into their cloud based subscription service. No amount of complaining is going to change their position. In my humble opinion.
