How to unload the Desktop code in Windows 8 Developer Preview?

    Question

  • How to unload the Desktop code in Windows 8 Developer Preview? I'm hoping to increase the battery life of my laptop so I can spend more time in the metro IE (with hardware acceleration so I can still play some HTML5 games).

    When you login you go straight to the start screen. As long as you never switch to the desktop a good chunk of code is never executed. This includes stuff like loading the desktop wallpaper, taskbar icons, desktop icons and a handfull of other things necessary to get the desktop into a working state. They simply aren't needed until it is time to venture into desktop land.

  • The desktop and Metro UI are running as "one" on your system. You can quickly switch between them, but you cannot disable either of them. Tablets only use Metro UI, Pc's and laptops use both. There is no way around this (yet).

    If you're asking how you can remove the Desktop stuff from Windows 8, you
    cannot. If that's not what you're trying to do then can clarify your
    question?

  • Hi,

     

    I don't necessarily need to uninstall the "Desktop" in Windows. "... And if you want to stay permanently immersed in that Metro world, you will never see the desktop—we won’t even load it (literally the code will not be loaded) unless you explicitly choose to go there!" (src: http://blogs.msdn.com/b/b8/archive/2011/08/31/designing-for-metro-style-and-the-desktop.aspx) Does that mean that the entire Desktop code is unloaded until I click the Desktop tile? Also, if I intentially or accidentally launched the Desktop app from the Start screen but later I decided to only use the Metro apps, would I be able to unload the Desktop code that was still running on my PC (to gain some battery life, maybe much)? Is it possible in the DP build anyway?

     

    Cheers,

    Michael

  • Hi Dylan,

     

    Thanks for your reply. But then can you explain the quote I mentioned above?

     

    Cheers,

    Michael

  • You won't see it but that won't mean it's not there. Am I missing something here? :O
