Right Tweaker is a free PC-based Smartphone tweaker which will help you with right softkey tweaking. By default, the phone opens Contacts program when you click the right softkey at the homescreen area. With right soft key tweaking, you can assign a new name and a new program to launch. Tweaking can be done on the phone using a registry editor or on the PC using PC-based registry editor.

HOW TO USE
 
To tweak
1. Dock phone to computer
2. Launch program
3. Type a name you wish to appear on the phone’s right menu
4. Type the full path of the file you wish to link or launch. Begin with a backslash when typing the path. Tested only on LNKs and EXEs. Do not type path to non-existent files.

For example: \Storage\windows\Start Menu\WMPlayer.lnk OR \Storage\windows\Start Menu\Accessories\Quickreset.exe

5. Wait for confirmation
6. Check mobile device
 
To revert to default settings
Just click on the Default button. Utility will revert to Contacts as default program launched (check image below).

 
 
If youd like to have the right soft key launch Start Menu (in case you have a problematic left soft key)

1. Open Notepad in PC then paste this code:
00#\Windows\appman.exe -s BootApps :MSStart tpcutil.dll AMStart

2. Save the file as Start.lnk (not in TXT extension). Transfer the LNK to phone (for example \Storage\windows\Start Menu).

3. Open Right Tweaker then type this as path:
\Storage\windows\Start Menu\Start.lnk

Do not type appman.exe -s BootApps :MSStart tpcutil.dll AMStart. It will not work.
