Make Windows Phone 7 Faster By Enabling Instant Resume [Hack]

Advertisement

Windows Phone 7Windows Phone 7 is a pretty competitive platform when it comes to speed. You can load a multitude of apps and still keep rolling without any significant performance degradation. But imagine this. You are playing a game on your WP7 device and all at once press the Home button to navigate to some other app or even text messages. When you come back to your game, it will take a while to reload it all over again. This is because of a feature in WP7 known as dehydration. Dehydration provides a buffer time when coming back to a running app from someplace else in the OS. This cushions the kernel for a while and allows it to resume the paused functionality at a leisurely pace. If you are following this train of thought, then you might already have guessed what’s coming next.

The trick is to find a way to disable dehydration for your task hosts. But this is by no means a simple endeavor. You will have to tinker a little with registry values and that is always risky business.

Disclaimer: Please follow this guide at your own risk. AddictiveTips will not be liable if your device gets damaged or bricked during the process.

However if you are still desperate for a faster OS, then here are the instructions.

instructions:

  1. Your device must be developer unlocked. If it is not, don’t despair, read our article about WP7 unlocking.
  2. Once you are sure that your device is unlocked, check for a registry editor. If you are not sure what is a registry editor and how to get it for your phone then you can read our article on registry editor for HTC.
  3. Open the registry editor and input the following path
    HKLM\Software\Microsoft\TaskHost
  4. This will open up some new options in a list. Look for DehydrateOnPause which will have a value of 3 against it. Change the value to 0.
  5. Save your changes and exit the editor.

Without even the need to reboot your phone you have made the changes to allow instant resuming of apps on your WP7. But unfortunately there are a few possible bugs which arise as the result of this app making life a little inconvenient. You can always revert back to your original settings by simply changing the registry values again though.

The hack has been proposed by Jaxbot on Windows Phone Hacker and all credit goes to him.
