Make Function Keys and Power User Menu Shortcut using AutoHotKey Script

I recently bought a Filco Majestouch Ninja mechanical keyboard. It doesn't come with all the fancy function keys, therefore I decided to create some function keys myself. I installed the AutoHotKey (AHK) tool and wrote an AHK script. I use the Windows key as a replacement for the Function (Fn) key typically found on laptop keyboards. Here is a list of my function key mappings.

Shortcut Functions
Win + Esc Put computer to sleep
Win + F6 Toggle volume mute
Win + F7 Turn master volume down
Win + F8 Turn master volume up
Win + F9 Skip to previous song
Win + F10 Play or pause song
Win + F11 Skip to next song
Win + F12 Open Network And Sharing Center

I use a Windows 7 on my desktop, but I found the Power User Menu shortcuts in Windows 8 come in handy, so I created them too. The Power User Menu is the pop-up menu which is displayed on the bottom left corner when you press Win + X on a Windows 8 computer. The script will not display the menu, so you need to remember the shortcut keys.

Shortcut Functions
Win + X, F Program and Features
Win + X, B Mobility Center
Win + X, O Power Pptions
Win + X, V Event Viewer
Win + X, Y System
Win + X, M Device Manager
Win + X, K Disk Management
Win + X, G Computer Management
Win + X, C Command Prompt
Win + X, A Command Prompt (Admin)
Win + X, T Task Manager
Win + X, P Control Panel
Win + X, E Explorer
Win + X, S Search
Win + X, R Run
Win + X, D Desktop

Here goes the script.
