Windows Phone 7 "Instant Resuming" hack makes the OS even faster [Homebrew]

Over at Windows Phone Hacker, developer Jaxbot has figured out a way to enable "instant resuming" on Windows Phone 7.

Of course, you'll need a developer unlocked device and as they state there are some "unintended consequences" (though we don't know what those are exactly, we imagine it's memory/resource related). By using a registry editor, you can navigate to:

HKLM\Software\Microsoft\TaskHost

and set "DehydrateOnPause" to 0 (defaults to 3)

The hack takes effect immediately and as can be seen above, it makes starting/resuming any task or game nearly instant as it disables 'Tombstoning'. In fact, this feels like multi-tasking, allowing you to "go back" to the last few apps, having instant access to them. Of course the downside is you can't shut down any app either--we imagine eventually the system will force close something. Anyways, it's easily undone if something goes awry, till then, we'll leave it on and see what happens.

Already rocking the hack, and loving it. Since I don't care about copy/paste, the only feature that really intrigued me was faster app loading / resuming. With this instant resume... and with the potential that all my hacks and side-loaded software will disappear with No-Do... I'm starting to hope the update gets pushed back another month! *GASP* lolll

Could you load a bunch of apps and note the performance? Does something inevitably get killed? I unlocked my phone last night and I'll probably try this when I get home, but I wanted to some feedback on potential cons.

I'll also wait with the update until there is a way to sideload apps after NoDo.Really great hack, btw. :)

So this wont be available on the Arrive which contains the update?

Disabling tombstonig is not always an advantage!Because many live tiles doesn't work anymore then.If that issue wouldn't be there it would be a very very nice hack!

So why did Microsoft set "DehydrateOnPause" to 3? Just to piss us off and slow us down. I don't think so. Interested to see what the battery hit will be like. I have the highest respect for the geniuses at XDA-Developers but I purchased a WP7 phone so I wouldn't have to spend two or three hours there every night. Enjoy the hack.

That is interesting, no doubt staging the arrival for "multi-tasking" .. all they need to do is build the memory clean up agents to auto shutdown apps and offer a "task manager" to close apps at will or configurable parameter via settings and you're done. Apple didn't implement multi-tasking for the same reason, concerns over battery life, remember? Keeping applications memory resident has to take a toll, but like others I wonder precisely what kind of toll... cool! Thanks for the information! I bet you NoDo leverages this setting to some extent haha.
