Windows 10: cannot trade to another interface
Alt tab only switches to open windows–those running in the taskbar. Shortcut keys are really not used as much in win 10. Just click on the running app in the taskbar. Pin shortcuts to favorite programs on the taskbar and/or the Desktop–Explorer is the
file folder icon on the left of the bar for instance and you can add any program by right clicking on the executable. Whatever you do–do not reinstall windows for this minor problem. That will do nothing to correct the shortcut keys and could cause major
problems. See this
“win 10 shortcuts” to see what you can do.
