Alt + Tab behavior is controlled by the Multitasking settings in Windows. The change described matches when Windows is set to show the Alt + Tab “switcher” UI (with thumbnails/tabs) instead of instantly toggling to the last window.
To restore the previous, faster behavior as much as possible:
- Open Multitasking settings:
- Select Start > Settings > System > Multitasking.
- Adjust Alt + Tab tab-display options:
- In Windows 11: Under Multitasking, find Display tabs from apps when snapping or pressing Alt+Tab and choose Don’t show tabs.
- In Windows 10 (recent builds): Under Multitasking, use the dropdown for Display tabs from apps when snapping or pressing Alt+Tab and select Don’t show tabs (instead of “20 most recent tabs”, “5 most recent tabs”, or “3 most recent tabs”).
This removes Edge browser tabs from the Alt + Tab view and simplifies the switcher, making it closer to the classic “last window toggle” experience.
- If using multiple desktops, verify Alt + Tab scope:
- In the same Multitasking page, under Desktops (or Virtual desktops), set Pressing Alt+Tab shows windows that are open on to Only on the desktop I'm using if the goal is to switch only among windows on the current desktop.
- Use the classic quick-toggle pattern:
- Press and release Alt + Tab once to switch to the last used window.
- Holding Alt and repeatedly pressing Tab cycles through open windows; releasing Alt activates the selected one.
If the setting was changed (for example by an update or by enabling Edge tab integration), reverting it as above restores the simpler Alt + Tab behavior.
