Tytn Tweaks

from XDA Developers


Mobile Media Player - storage card unrecognised

Delete MSMETADATA and WMDRM folders from storage card. Soft reset. Update media library.


Today Soft Keys

Left soft key app:
HKCU\Software\Microsoft\Today\Keys\112\Open = "\Windows\Calendar.exe" (REG_SZ string, including quotes) or
"\Program Files\Agenda One\Agenda One-month.lnk"
Left soft key title:
HKCU\Software\Microsoft\Today\Keys\112\(Default) = "Calendar" (REG_SZ string, no quotes)
Right soft key app:
HKCU\Software\Microsoft\Today\Keys\113\Open = "\Windows\Start Menu\Programs\Contacts.lnk" (REG_SZ string, including quotes)
Right soft key title:
HKCU\Software\Microsoft\Today\Keys\113\(Default) = "Contacts" (REG_SZ string, no quotes)

Note that 113 normally doesn't exist by default, and probably needs to be created

Also note that there is at least one application that allows you to set these through a GUI, developed by FdcSoft called SoftKeyAppletEx.


Taskbar Icons

HKLM\services\power\?ShowIcon = change from 1 to 0 (remove)
Wireless connection manager:
HKEY_LOCAL_MACHINE\Services\?WirelessMgr\keep and change the DWORD Keep to 0, (remove) soft-reset
Screen Rotation:
HKLM\services\screenrotate\?ShowIcon = change from 1 to 0 (remove)

If you remove all three icons, taskbar will be removed and more space on today screen.


ClearType in Landscape

HKLM\System\GDI\ClearTypeSettings\OffOnRotation = 0 (DWORD decimal) (1=disable)

Note that your PocketPC screen's LCD red/green/blue ordering required for proper ClearType display is only correct for portrait display.


Keyboard Backlight Duration

HKCU\ControlPanel\Backlight\QKeyLedTimeout = 30 (DWORD decimal) seconds


Taskbar Clock

HKLM\Software\Microsoft\Shell\TBOpt = 0 (DWORD decimal)
HKLM\Software\Microsoft\Shell\TBOpt = 1 (DWORD decimal)
HKLM\Software\Microsoft\Shell\TBOpt = 2 (DWORD decimal)
Date and Clock:
HKLM\Software\Microsoft\Shell\TBOpt = 3 (DWORD decimal)

Note 1: If you switch to the Analog clock display, the date will remain visible -through- the Analog clock

Note 2: Setting the clock to show 'nothing' will still keep the reserved space, showing the taskbar background, and obscure any icons that will shift to the right.

Note 3: Your date may get obscured by the space reserved for the OK/Close button in the top-right. You can fix this my adding spaces at the end of your 'Short Date Format'. See also the tweak on 'Change the Short Date Format'


Today Custom Text

HKLM\Software\Microsoft\Shell\DeviceBeta\Today = "Beersville" (REG_SZ string, no quotes)

Please note that this text won't take up today item text. It will be obscured by today items.


Today Network Operator

including WiFi and Bluetooth


Create "Wireless" use Key







Enable by clicking on the today plug-in above to open Comm Manager, (this mucks up the Connectivity icon pop-up window).


Create String Value "Redirect" = "\Windows\CommManager.exe"


Operator's Name Customisation

HKLM\SOFTWARE\OEM\PhoneSetting\ONSDisplayRule=0 (DWORD decimal)

Then at HKLM\SOFTWARE\Microsoft\RIL\Operator Names

add the code and the name to display. The value is 5 digits "CCCOO", where CCC is 3-digit country code, and OO is 2-digits operator's code. For example: "23433" = "Orange UK". See Wikipidea for country and network codes.

To show operator name based on the SIM card used (eg. for cases where dual SIM adapter used), set HKLM\SOFTWARE\OEM\PhoneSetting\ONSDisplayRule=1 (DWORD decimal)


Phone Dialler Skin Background(s)

HKLM\Security\Phone\Skin\PROGRESS\portrait\other HKLM\Security\Phone\Skin\PROGRESS\landscape\other

HKLM\Security\Phone\Skin\DIALER\portrait\other HKLM\Security\Phone\Skin\DIALER\landscape\other

value bmpNormal \Windows\BKGND_Port.bmp value bmpNormal \Windows\Bkgnd_Land.bmp

I resized the picture to the correct size and changed the keys to BKGND_Port1.bmp and rebooted.


Pocket IE up/down navigation with four-way pad

Rather than jumping between hyperlinks and form fields.

HKLM\Software\Microsoft\Internet Explorer\Navigation\4-Way Nav = 0 (DWORD decimal)

Note that you may still jump between links using Tab and Shift-Tab if your Device has a built-in hardware keyboard.
