windows 7 - Maximize All on a PC

I know that WinKey+M and Winkey+D will essentially minimize all windows and show me my desktop. However, I have been unable to locate a similar shortcut key that either maximizes or restores all windows. Is there a pre-existing way to do this in Windows 7? I'd rather not mess with the BiOS if I don't have to.

Answer

Well, I doubt that it is really the answer that you are looking for, but on Windows 7, you could save this as a powershell script somewhere:

$dllInfo = '[DllImport("user32.dll")] public static extern bool ShowWindowAsync(IntPtr hWnd, int nCmdShow);'
Add-Type -MemberDefinition $dllInfo -name NativeMethods -namespace Win32
foreach($proc in Get-Process){
    $hwnd = $proc.MainWindowHandle
    # Restore window
    [Win32.NativeMethods]::ShowWindowAsync($hwnd, 4) | Out-Null
}

Then bind a key to run that script.
