To change Windows to suit a Mac user, see this article : Key Remapping in Windows.
It contains an Autohotkey script that maps many Windows keys to their Mac equivalents.
To build a new keyboard layout, see The Microsoft Keyboard Layout Creator, which lets you manipulate all keys and their combinations.
As the original article has disappeared from the Web, I copy below the
Autohotkey script:

;following section remaps alt-delete keys to mimic OSX
;command-delete deletes whole line
#BS::Send {LShift down}{Home}{LShift Up}{Del}
;alt-function-delete deletes next word
!Delete::Send {LShift down}{LCtrl down}{Right}{LShift Up}{Lctrl up}{Del}
;alt-delete deletes previous word

4Alt+F4 closes windows, not programs. You can probably cook something up in AutoHotkey, but since Windows program commands don't always show up in menus, you might lose some commands that are executed using Ctrl/Alt+Q – Daniel Beck – 2011-02-25T20:19:11.077
1Alt+F4 will close a program for me. I just checked the 'Quit' command in Word and it's Alt+F4. Perhaps a registry edit? Not sure where to look though. – v15 – 2011-02-25T20:20:25.130
4If programs close when their last window is closed, then yes, Alt+F4 closes programs if you use it to close their last open window. But it's not generally a "quit program" shortcut. There's no such thing as the Keyboard Shortcuts preferences pane in OS X on Windows. Your only hope is input redirection (like I suggested) or a third-party tool. – Daniel Beck – 2011-02-25T20:40:07.823
1In my Windows, ALT+F4 also closes the whole program, even if it has more than one document/window opened. STRG+F4, however, closes a single document window. This is applicable to most, if not any, programs I use on Windows. – Martin – 2011-04-26T14:07:20.347
