MCE05 tricky key combination

I'm trying to write up a quick little script that sends the key combination for the "green button" in all Windows Media Center Edition setups.

The combination is, interestingly enough, [WIN] + [ALT] + [ENTER].

I tried using SendKeys(), but had no luck locating the windows key... is this key combination even possible to perform using a script? Basically I was trying this code in hopes that it can be done painlessly, but had no such luck.

Code:

---

dim oShell
set oShell= Wscript.CreateObject("Wscript.shell")
oShell.SendKeys "{ ......................? }"
WScript.Sleep 100

---

The keycode for the Win key is 91. It's 18 for the ALT key and 13 for ENTER.

Hope this helps? I'm not really familiar with what you want to achieve.
