Disable MRU in Alt+Tab task switch

Solution 1:

For Win7, the tool 7+ Taskbar Tweaker can assign a keyboard shortcut to cycle back and forward in visual taskbar order. See the help file under section Advanced>Keyboard Shortcuts. It lets you assign key codes to actions 101 and 102:

101 - Switch to the window which is located on the left to the active window on the taskbar. 
102 - Switch to the window which is located on the right to the active window on the taskbar. 

For Windows XP, which is still a preferred OS to me due to superior responsiveness of UI - TaskbarNavigation seems to be the only currently available solution. There were previously some quirks with Windows not allowing applications to steal focus causing the window to not come to focus but only flash on taskbar. See SetForegroundWindow restrictions problem for which TaskbarNavigation implements some hackish Dllcalls.

However with recent investigation, there may be better methods with SystemParametersInfo(win32con.SPI_SETFOREGROUNDLOCKTIMEOUT or emulating the Alt key before switching or DllCall to RegisterHotKey.

If you want to provide some more feedback on the AutoHotkey forum regarding where performance is to be desired, perhaps it can be improved/fixed/perfected. Adding "#UseHook, Off" may also fix problems.
