Windows 8 Start Screen Launcher v1.1This simple executable will launch the Start Screen on Windows 8, so you just need to pin it to your taskbar and no need to install those other applications that mimic the old StartMenu since you only need a button lo launch StartScreen.
This will just trigger a message to Windows that will launch the Start Screen.
USAGE:• Execute Deploy.cmd, it will rename the executable to .EXE for you.
(Win8StartScreenLauncher.ex_ ~> Win8StartScreenLauncher.exe)
• Just pint Win8StartScreenLauncher.exe to your Taskbar
(drag and drop in an empty area), and that's all.
• Don't like the default icon? Customize it:
If you don't like the default icon, you can download any other icons from IconArchive.com or other free icons library site. Once downloaded those icons, just drag and drop over this application, it will create a new link that will be using that icon. Finally, pin that new shortcut to your Windows taskbar.
Worried about your memory usage?This executable just launches the StartScreen, after that it kills itself
, i.e. this application won't stay in memory.

[link]There is also another executable "Win8StartScreenLauncherNoStartMenu" that will handle those third party StartMenu applications that hooks messages that Windows 8 listens to launch the StartScreen.

Bottom left hot corner disable due of using Start8. This app are use on WinX menu. WinX Menu editor lack of not have parameter add support for app. And making batch file not working on WinX menu. Thx for this app, i can launch start screen without use keyboard but have to make 2 click on mouse.
Thanks for your observation.
Rename to whatevernameyoulike.7z and uncompress, there you will find the executable for the following source code compiled with Flatassembler.
include 'win32ax.inc'
.code
start:
invoke MapVirtualKey,91,0
invoke keybd_event,91,eax,0,0
invoke Sleep,10
invoke MapVirtualKey,67,0
invoke keybd_event,67,eax,0,0
invoke Sleep,10
invoke MapVirtualKey,67,0
invoke keybd_event,67,eax,2,0
invoke Sleep,10
invoke MapVirtualKey,91,0
invoke keybd_event,91,eax,2,0
invoke Sleep,10
invoke MapVirtualKey,13,0
invoke keybd_event,13,eax,0,0
invoke Sleep,10
invoke MapVirtualKey,13,0
invoke keybd_event,13,eax,2,0
invoke Sleep,10
invoke ExitProcess, 0
.end start
It is faster than a vbs script. Just create a shortcut for that executable and customize that shorcut's icon and pin it onto your taskbar.
A shorter one without MapVirtualKey and EAX changed to 0
