Get Windows XP Styled Classic “Alt+Tab” Switcher Screen in Windows Vista and 7

1. Type regedit in RUN or startmenu search box and press Enter. It'll open Registry Editor.

2. Now go to:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer

3. In right-side pane, create a new DWORD value AltTabSettings and set its value to 1

4. That's it. Now whenever you'll press "Alt+Tab" keys together, it'll show Windows XP styled classic "Alt+Tab" Switcher screen instead of the new screen.

5. To restore default Aero enabled "Alt+Tab" Switcher screen, simply delete the AltTabSettings DWORD value created in step 3. Log off and login again to take effect.
