-Having to move the mouse all the way into the last 1 or 2 pixels of the corner to active the Start screen, and worse yet activate the charms bar is very annoying. I would rather there be a visible button to click for each corner, yes a return of the Start button would not be out of the question so long as it just brough up the Start screen and not a menu.
Relatively easily fixed. I've done it - I found myself moving mouse to start button area on auto pilot and launching IE so often...
Create a file startscreen.vbs (yeah I know, powershell nicer but too slow to start up). Contents:
set oShell = CreateObject("WScript.Shell")
set oShell = Nothing
Create a shortcut to startscreen.vbs on the desktop.
Open properties on the shortcut and change the target property to:
C:\Windows\System32\wscript.exe C:\Users\[[my user name]]\Desktop\startscreen.vbs
Change the drive location & path to script as required.
Still in shortcut properties, change the icon. %SystemRoot%\System32\imageres.dll has a windows icon in it. Close properties.
Right click the shortcut and "pin to taskbar". Move it to left hand side. Job done.
