Registry Tweaks
Like previous Windows Mobile devices, Windows Phone 7 devices have a registry that handles much of the system related values. "Registry tweaks" allow the user to optimize settings or enable previously disabled features, customize themes, etc., through a registry editor. Such tweaks will require that a device is interop unlocked.

Instant resuming/Jaxbot's Dehydration Hack
Enables instant resuming (see demonstration)
[HKEY_LOCAL_MACHINE\Software\Microsoft\TaskHost] "DehydrateOnPause"=dword:0
Change max unsigned apps/Interop unlock
This hack has become somewhat redundant, as it typically requires interop unlock to be changed, but it is used in all exploits that enable interop unlock.
[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg\Install] "MaxUnsignedApp"=dword:300 (default for unlocked: 10)
Recall that interop unlock is enabled once this value is set to 300 or above.
Prevent Relock
[HKEY_LOCAL_MACHINE\Software\Microsoft\DeviceReg]
"PortalUrlProd"=""
"PortalUrlInt"=""
Enable "never" screen time-out
[HKEY_LOCAL_MACHINE\ControlPanel\Lock] "DisableNever"=dword:0
Customize sounds
This requires custom sound files to be copied onto the device. The location of the sound keys are:
[HKEY_CURRENT_USER\ControlPanel\Sounds]
Where setting "Sound" changes the path for the sound file. For example:
[HKEY_CURRENT_USER\ControlPanel\Sounds\SMS] "Sound" = "\My Documents\Test.wma"
Would change the SMS sound to Test.wma.
Customize colors
The location for color settings is:
[HKEY_LOCAL_MACHINE\ControlPanel\Themes]
The corresponding names and numbers are listed as:
[HKEY_LOCAL_MACHINE\ControlPanel\Themes\0] Light theme [HKEY_LOCAL_MACHINE\ControlPanel\Themes\1] Dark theme [HKEY_LOCAL_MACHINE\ControlPanel\Themes\AccentsDisplayName] 0 = Green 1 = Red 2 = Blue 3 = Mango 4 = (OEM, e.g. HTC) 5 = Pink 6 = Brown 7 = Lime 8 = Teal 9 = Purple 10 = Magenta
The customizable colors are:
[HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\Accents\[accent number]] # The various accent colors [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\BaseThemeColor] # The background color [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\ChromeColor] # The color of context menus, etc [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\ContrastColor] # The color opposite, e.g. for white text [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\KeyPadBackground] # Keyboard background color [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\ListPickerBackground] # Self explanatory [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\ListPickerBackgroundPressed] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\PageBackgroundColor] # Silverlight background color [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\ProgressBarBackground] # Self explanatory [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\ProgressBarDisabledBackground] # Self explanatory [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\SysTrayBackgroundColor] # Background color of the top bar (with time, carrier icons, etc) [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextHighContrast] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextNeutralColor] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextNeutralColor20] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextNeutralColor30] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextNeutralColor60] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextNeutralColor75] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TextNeutralColor80] # ? [HKEY_LOCAL_MACHINE\ControlPanel\Themes\[0 or 1]\TransparentBackgroundColor] # The color displayed when the screen dims for a popup, e.g. when the Speech popup is opened
Disable Accelerometer
This requires a reboot, so it's not particularly useful for, say, orientation lock. It's fun to play with, though.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Accelerometer] "Pdd" = "" # it's probably better to set this to, say, accpdd.dll_, so you will be able to easily revert back
