Why don't I have the app and features in settings?

thank you

Fixed it.

You need to switch out of S Mode.

This works when you know you are NOT in S mode and the Option in settings to "Choose where to get apps from" is missing.

Start regedit with administrative privileges.

Go to this location in registry. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer .

Find this in the center panel and double click
AicEnabled 

In the box that just appeared replace the line that spells StoreOnly or any of the other 2 words listed below with the word Anywhere.

Hit OK

Anywhere = Anywhere
Recommendations = Anywhere, but let me know if there's a comparable app in the Microsoft Store
PreferStore = Anywhere, but warn me before installing an app that's not from the Microsoft Store
StoreOnly = The Microsoft Store only

Close regedit

Restart PC

Fixed!!!!!!!!!!!

I tried all the suggestions including S mode to no avail. I stumbled on a link and voila, I was able to actually deactivate the permissions; albeit permanently. However, I can now download and install any applications I want. http://www.techbout.com/switch-off-S-mode-windows-11-71395/
